Author Topic: 7.62x54R Rechamber: Good or Bad Idea? (Read 4614 times)

Mainer · « **on:** August 07, 2005, 05:25:14 AM »

I've been toying with the idea of sending a Handi to the factory for a 7.62x39 barrel and then sending it to a gunsmith to be rechambered to 7.62x54R.

The 7.62x54R round fires a .311 cal. bullet. The twist rate for the Mosin-Nagant rifles for which those rounds were manufactured has a 1-in-10" twist rate. I hear that the 7.62x39 H&R barrels are .310 cal. and have a 1-in 9.45" twist rate. It seems to me that the 7.62x39 barrel would make the perfect platform for a 7.62x54R rechamber.

Here are the pros of the idea:

(1) There is a mountain of inexpensive 7.62x54R ammo out there--and at least some of it appears to be of quite good quality.

(2) The 7.62x54R appears to be ballistically very similar to the .308 Win. Therefore, it would seem to be an ideal whitetail deer cartridge (IMO) when loaded w/soft-point ammo.

(3) The potential advantage of the 7.62x54R cartridge over the .308 Win. is that the 54R is a rimmed cartridge--and, therefore, MAY eject more reliably from a Handi--especially when comparing surplus ammo to surplus ammo.

(4) A 54R Handi would be something unique--but still practical.

Here are the cons:

(1) Cost. Approx $100 for 7.62x39 barrel. Est. $200 for rechamber and ejector modification. Total $300+/-.

(2) Separation anxiety. I would have to "give up" a Handi Rifle for quite some time. First to send to H&R. Then to send to a custom gunsmith.

(3) Somewhat limited supply of reloading components (bullets for .303 Brit could be used).

(4) Limited supply of factory loaded hunting ammo.

I'm thinking of 54R instead of .303 Brit because (1) there appears to be far more 54R surplus ammo available (2) I already have a Mosin-Nagant chambered for 54R but don't have a rifle chambered for .303 Brit and (3) it appears the 54R has a power advantage over the .303 Brit (but the Brit is still a fine cartridge).

What do you guys think? Does anyone already have a .303 or 54R Handi? How difficult would it be to have a gunsmith fit an ejector for 54R?

Well...having a custom Handi is kinda fun...you get to break into new territory...but..as with any of the Handi's...I'm not so sure about using Mil-Surp ammo...NEF advises against using it...and from I've found for the 308...and others for other calibers...the ammo tends to stick in the chambers more often than not..but...this might be a problem with a new chamber that is well within specs and not sloppy...Having a limited supply of bullets to work with can be a pain..especially if your rifle doesn't like them...The $200 rechambering fee...seems excessive to me...you might want to give Wayne of Oregunsmithing a call and see what he can do for you...http://home.earthlink.net/%7Eoregunsmithing/id13.html...other than that ..If your wanting one for the uniqueness..go for it..but if your just wanting to get the performance of the 308 out of it...then just get a 308...

If I wanted .308 Win performance but didn't want the risk of having stuck brass, I'd order a .308 barrel with the extractor instead of an ejector. And as Mac has stated, milsurp in a Handi is not a good idea no matter what the caliber as those that tried to shoot 7.62x39 milsurp in theirs found out.

Well I do know that the Russians have been reloading the 7.62x54R for years. And have heard that they made some crazy wildcat stuff off of it.
I would love to have a Handi chambered in it.
At the same time you should keep in mind that a lot of the Mil. Surplus ammo is loaded very, very hot. Some think that a lot of nations loaded their ammo beyond safe levels. Even though there are tons of this ammo floating around, you have to take into consideration too that most of it is:
1-Corrosive. You would need to do some thorough cleaning afterwards. Barrel, and action.

2-Steel Jacketed/Steel Core ammo=extreme penatration=very
dangerous. And increase your chance of shooting out your barrel faster.

3-Steel cased. In which the Handi's haven't had a good track record of spiting them out of the chamber.

Mainer · « **Reply #4 on:** August 07, 2005, 07:54:52 AM »

I hear what you say about Handi's having a reputation for sticking mil-surp ammo. However, might not the 54R be different since it has a rimmed case??

Mac: If you think Wayne would due the rechamber/ejector modification for substantially less than $200 then I might not be able to pass up this project.

Mainer · « **Reply #5 on:** August 07, 2005, 08:11:41 AM »

I just sent Wayne an e-mail describing the project and asking for a quote. If he thinks it's doable, and quotes a reasonable price, then I'll probably go ahead with this project. :grin:

And if it doesn't work out and you find you don't shoot it as much as you thought you would, make sinkers for your catfish pole. :-D

If you do this shoot sellior and bellot ammo it's cheap and brass cased. It's loaded pretty hot too but should be plenty safe in a handi.

lostsniper308 · « **Reply #9 on:** August 07, 2005, 11:54:03 AM »

i think its a good idea. Albeit steel cased the Wolf and Barnaul ammo is accurate stuff for my M91-30 and no real difficulty chambering

Stan in SC · « **Reply #10 on:** August 07, 2005, 01:03:12 PM »

It is quite doable from all aspects but one.The people who have gotten 7.62X39 barrels have had problems with fail to fires due to the "hard" military primer.I would hate for you to have all this rechambering done and then it will not fire milsurp rounds.
You would almost be foreced to shoot nothing but reloads.Something to think about.

Stan

Mainer · « **Reply #11 on:** August 07, 2005, 03:01:46 PM »

Stan: Your point about hard military primers leading to missifires is a good one. I've been pondering this project this afternoon and that's my one big concern. :?

handirifle · « **Reply #12 on:** August 07, 2005, 03:43:19 PM »

Our local Big 5 sporting goods store has the MN rifles on sale for $89 ALL the time. That would be a lot easier/cheaper and better in the long run.

Diesel Man · « **Reply #13 on:** August 07, 2005, 03:50:05 PM »

I own a few of the M/Ns and found some 180gr. brass case ammo made by prvi partizan in a white box $10 for 20 not bad to shoot and fully reloadable brass case. I hope this helps.

myarmor · « **Reply #14 on:** August 07, 2005, 04:27:37 PM »

Most surplus is metal cases, but it is nice when you luck up on some decent brass ammo. All my Nagants love the brass a lot better than steel cases. They tend to stick too, and many suspect it comes from laqure build up. But that has been a source of debate.
I think it would be sweet to have a Handi chambered in the "Big Russian"
, though from an economical stand point, it's a lot cheaper to pick up a $50-100 M44, 91/30, or M38 in very good condition.
But I hate having to drill and tap my receivers for a scope, not to mention making up a new low bolt handle.

DPRinks · « **Reply #15 on:** August 07, 2005, 04:35:15 PM »

My armor;
Have you tried Darryl's scout scope mounts?
I have them on my K31 and M44, easy to install and work fine.

myarmor · « **Reply #16 on:** August 07, 2005, 04:45:17 PM »

No I sure haven't. I have seen them, but not up close.
I'm not the biggest fan of scout scope mounts, but to be fair and honest, :oops: I have yet to actually put one to the test. I would like to try it before I dis it. I have a few M44 I play with, if I found one local I would consider it. Only problem is I have too many projects going on, with a new 44Mag in the Handi family and a 30-06 UltraComp still playing with. I hope to supply a range report with the goods in a couple of weeks.

Diesel Man · « **Reply #17 on:** August 07, 2005, 04:46:28 PM »

It takes a little work but I made my own scout mount out of a steel block and an old weaver mount I had around, the only bad thing is the long eye releve scope for long range. A Handy would be cool in this chamber. If you were having a smith do the chamber take him a hand full of surplus rounds to match up with.

Mainer · « **Reply #18 on:** August 07, 2005, 04:52:00 PM »

Well, I've done some more research on this project and here's what I've found out.

(1) It seems like the problems with the mil-surp 7.62x39 ammo in the Handi is that the primers are recessed, due to the potential of some military arms to slam fire. I've inspected some Russia 54R ammo I have and the primers are flush.

(2) It appears that the 7.62x39 barrels are being produced with an extractor, not an ejector. Although in concept I would prefer an ejector, it may be that an extractor would be better for unloading sticky mil-surp cases.

Thus, this project remains in the realm of the possible!! :grin:

Diesel Man · « **Reply #19 on:** August 07, 2005, 04:58:42 PM »

I also think part of the problem with surplus ammo being boxer primed if the firing pin is not long enough it don't drive the charge into the anvil and set off the charge. This is cured by setting the pin out a little farther on surplus rifles, not able to be done on a Handy.

stiff neck · « **Reply #20 on:** August 08, 2005, 04:23:46 AM »

Sounds like a lot of work and money for a project. I searched for a year until I found the "perfect" Mosin Nagant 91/30 at Big 5. It was even on sale for $79 complete with bayo, sling, cleaning kit, etc. My gunsmith checked it over and said it had probably never been fired outside the factory. Wood was near perfect, bluing was 99%, bore was 99% and crisp. Not bad for a rifle made in 1939! It shot so well with iron sights that I added a reproduction PU sniper mount with a 4x scope and had the bolt bent. It shoots under an inch at 100 yards with S&B 174gr BTHP ammo. I've only used it for coyotes so far, and it works fine, just a little heavy. The whole project cost me about $400.

stiff neck · « **Reply #21 on:** August 08, 2005, 04:36:05 AM »

Also, you'll find that as with most <a style='text-decoration: none; border-bottom: 3px double;' href="http://www.serverlogic3.com/lm/rtl3.asp?si=31&k=military%20surplus" onmouseover="window.status='military surplus'; return true;" onmouseout="window.status=''; return true;">military surplus calibers, American ammo manufacturers load them to anemic levels to reduce liability or whatever. Military surplus ammo is always much "hotter" than modern comercial stuff. Except for European stuff. S&B is HOT, and Wolf is typically hotter than American stuff but not as hot as S&B.

A box of Remington x54 ammo is therefore weak, and is comparable to the 308. But S&B stuff is zippin closer to 30-06 levels, and Wolf is right behind.

Wow-stiffneck...that is an absolute gorgeous 91/30 :eek:
Sweet piece man, very sweet.

Longcruise · « **Reply #23 on:** August 08, 2005, 07:29:36 AM »

I found the Czech Silver tip to stick in three MN's on a very hot day last summer. Is it sticking due to hot ammo or is the lacauer melting and sticking?? :? I'm not sure but would concur that the surplus ammo is loaded hot.

The 54r is made for the reloader. It's easy to reload if you are willing to accept the limited variety of bullets for it. I loaded some 225 grain bullets in mine last year that were stepping along at about 2400 fps. That's big medicine my friends :shock: IMO, the 54Rway outclasses the .308 in performance and easily matches the '06.

There are all kinds of practical reasons not to do the rechamber, but if you read enough of the threads on this forum it is obvious we are not a practical bunch. If we were, we'd be spending all this dough on lawn care equipment :-D :-D

In addition to possibly shooting mil-surp ammo, as Longcruise indicates, the reloading possibilities with the 54R are great. Midway's website lists a number of .303-class bullets, plus Starline is offering reasonably priced brass.

Today's downside is that Wayne York (the gunsmith) said his turnaround time would be December. :cry: He seems like a good guy, though. Sounds busy. And he quoted a fair price. $50-$75 for labor plus the cost of renting a reamer.

However, the slow turnaround time makes me want to investigate whether I could do the chamber reaming myself or whether I could find a competent local smith to do it.

myarmor · « **Reply #26 on:** August 08, 2005, 02:53:01 PM »

I don't know why I didn't ask this, but do you want a 22" barrel in 7.62x54R? Nothing wrong with that. Short, yes. Maneuverable, of course.
In a Handi, I think a 26" would be awesome and still be short enough for great velocity and a nice hunting package. Not nearly as long as a 91/30 too.
Then again, I believe we all would like to see more calibers offered in a 26" barrel.

Diesel Man · « **Reply #27 on:** August 08, 2005, 03:04:59 PM »

The other day at the "W" mart I found this mag called Hand Loader and they had a whole story on the load test for the 54r they listed loads and bullets. The guy was surprised with the results as well, and from what I've found the 54 is more like the 06 on 200g and less loads than the 308.

stiff neck · « **Reply #28 on:** August 08, 2005, 03:53:22 PM »

I refinished the stock myself. It was in good shape when I got it, but the original shellac tends to flake off with use, so I refinished it so I could use it for hunting.

Fred M · « **Reply #29 on:** August 09, 2005, 07:07:24 AM »

I would not waste my money on a conversion like that, when you can get a Handi in 308 Win. Were you can get cheap milsurp brass, cheap milsurp bullets, even milsurp powder. Besides you can get the finest loaded target or hunting ammo.
