Author Topic: 410 to 45 colt reaming question (Read 1640 times)

Is it possible to ream an older .410 to make it a .45 Colt or have I lost my mind?

RPRNY · « **Reply #1 on:** March 16, 2013, 03:15:01 PM »

Can you shoot cowboy load 45s down a .410 smooth bore barrel without it blowing up? Maybe. Maybe only the choke will split. But it will be an ever present danger forcing a .454 projectile down a .410 bore? Yes. It would have no accuracy and it will fail eventually, perhaps quite spectacularly.

BAD idea.

Well, that's not exactly my question but maybe I am not clear. Can you rechamber and rifle a shotgun barrel that is chambered for .410? Not shoot a 45 colt down a 410 cahmber.

+1 bad idea

but fi you had to..........
cut off the choke and slug the bore first....then decide
too much to loose with too little to gain

i prefer OOO buck in a 410....or #4 shot

ousooners1baby · « **Reply #4 on:** March 16, 2013, 03:28:44 PM »

NVMND. You would need a lathe and someway to bore chamber to specs. Then be able to rifle it. Stupid question I guess. Buy a barrel already made. My point was as if you bought a green mountain blank(my current 2000 .410 barrel) how do you make it chambered for what you want(.45)?

too much free bore....but sure it could be done

jeepmann1948 · « **Reply #6 on:** March 16, 2013, 03:51:46 PM »

Best way would be to stub the 410 barrel with a 45 caliber barrel and fit it to a SB2 frame.
Low pressure loads, ie. "Cowboy Black Powder level" loads could be used on the shotgun frame but you are asking for trouble with the Ruger level loads!
Good Luck

start with a 44 mag
or just buy a 45 lc
there is one on the clasifiedes he wants too much
but still better and cheaper than converting a 410
i just sold 2 on gunbroker....i reamed them to 454 cassul

You would be much farther ahead to get a different barrel. I originally thought I would only fire cowboy action loads from mine, but settled on a great shooting load that would turn a SAA inside out.

Thanks, Dinny

Dinny. If I send it in, to be fit to an sb2, for the 45/410 barrel and cut off 2 inches can I shoot Ruger loads?

colt1960 · « **Reply #10 on:** March 16, 2013, 04:58:18 PM »

I thought the new fitted barrels from H&R were made for both. Ive heard you just remove the choke to shoot the 45lc. they come rifled also ive heard. I would just have one fitted to the receiver.

bikerbeans · « **Reply #11 on:** March 16, 2013, 04:59:18 PM »

You probably could have a 410 barrel rebored and rifled to .452. It would be expensive and you would have a shotgun steel barrel so you would have to keep the pressures down to 45 Colt levels. Also, a 45 colt reamer wouldn't cleanup the 410 chamber as the 410 is much longer, so as mentioned you would have a big freebore jump to the rifling. If you bought a GM barrel blank then you might as well buy a .452 rifled blank and save the reboring cost, which ain't cheap. Unless you have the knowledge and access to a lathe & mill you would be much better off to wait and find a 45LC Handi.

Thanks Beans. Your answer was easy to understand and precise. I appreciate that. I will send it it.

45-70.gov · « **Reply #13 on:** March 16, 2013, 05:21:17 PM »

everything mentioned is expendive or dangerous
just to salvage a barrel and ammo you already have?

?...what is an eye worth?

xpensive but the best way to go
http://www.gunbroker.com/Auction/ViewItem.aspx?Item=332790241

or just
buy some 410 slugs
or buy another calibre
or forget it

Yes, but you will not be real happy with the accuracy. There are many posts archived in the basement of GBO regarding loads for the 45/410 barrel.

So, the combo barrel does not shoot the Colt loads well?

No, not really. Some have modified their loads for decent accuracy. I don't know the specifics, as I have never owned one, but it's here somewhere.

Thanks, Dinny

gcrank1 · « **Reply #17 on:** March 17, 2013, 03:53:02 AM »

Some have developed accuracy loads, but you have to have some experience messing about with oddball stuff, its not as user friendly as the proper barrel/chamber to start with.
I guess a good way to put it is,"advanced techniques required".

LaOtto222 · « **Reply #18 on:** March 17, 2013, 04:25:11 AM »

For the cost of reaming/rifling a 410 barrel, you can buy a whole gun in 44 Magnum. I do not think they are making the 45 colt barrels any more. You could always buy one used, but by the time you pays your money and shipping and such you will not be that much short of a whole gun. If a 44 Magnum is too weak for you, then you could ream it to 445 Super Magnum or buy a 500 S&W gun. 44 Magnums can be very accurate.

That was with a 1.3X scout scope where the cross hairs were covering the 2" target. These were shot at 50 Yards. With a higher resolution scope, I could make this rifle group closer.

The rifle

Good Luck and Good Shooting

Or a 444 Marlin that you can handload from 44Spl. on up to full 444 loads (and those long cases are just cool).

a4beltfed2000 · « **Reply #20 on:** March 17, 2013, 12:33:20 PM »

I have one of the .410/45lc barrels, and as stated they are not the most accuriate. mine using cowboy loads, shoots about 3-4 inch groups at 30 yards, using just the bead sight. not clover leafs by any means but somewhat close enough if need be.

Now this post got me thinking a little. If the 45lc/410 barrel was made of 41xx series steel such as with high powered rifle barrels and it was used on a SB2 frame, could you in use 454, 460 rounds in the barrel as well, or maybe even a 45/70 round and still be able to shoot .410 with the removeable scope?

quickdtoo · « **Reply #21 on:** March 17, 2013, 12:50:57 PM »

The 45-410 barrel isn't 4140, it's 1137, confirmed by Tim Looney at H&R/Marlin a long time ago.

Thanks for the correction, I didn't realize they used different steels. Where is the money saved in using different barrels steels? One would think it would save in liability to use one steel capable of handling the pressures of any cartridge they chamber. Just think what would happen if one of those 1137 barrels got thrown onto the 270 Win pile.

Thanks, Dinny

Let's sum this up!

Only shoot Cowbuy loads in the combo barrel. The barrel is not hard enuff to support heavy loads.
If'n you want to shoot Ruger level loads in a buy an old carbine 45.

Don't believe everything you read my friend.

The 45/410 can be just as accurate as any of them but it needs a little work.
First it needs some real sights or some kind of optics on it. A bead is fine for a shotgun but not so good for rifle accuracy. Just like anything else you have to find a good load for it. My 45/410 shoots best with stiff loads and jacketed bullets if I'm using 45LC brass. If I'm using 460 brass I stick with Trailboss and cast bullets.
This barrel doesn't really deserve all the bad press it gets... what it needs is an owner who's willing to tinker with it... and some sights.

you didn't state your reason to do this

1-cause you already have bullets and barrel.....just forget the bullets and buy some slugs
2- you want to shoot this power level as chaep as possable......buy a 44 mag
3- want to shoot same round as handgun [and load for]...find an old 45cl carbine..
.still probly cheaper than any modifications
4-you ask if you lost you mind........no comment.......i have tried dumber...
5-can i load 54cal muzzle loaders slugs in my 28GA...or have i lost my mind too?

??

Ease up 45-70... it sounds like he's got a project in mind and is looking for guidance... not redirection.

Heck we've all got some kind of project in our heads don't we?? I've been trying to figure out a breechplug for a 12ga. Pardner to make it a muzzleloader. So far I've found some good info on the web... even here on GBO.
It's all part of the fun far as I'm concerned.

I've already got a 45/410 but I'd like to have a rifled 410 barrel myownself... It'd be fun to work up some brass cased cast bullet loads for it.

Keep at it ousooners... you'll get there.

ousooners1baby · « **Reply #28 on:** March 19, 2013, 07:02:35 AM »

Since this is so important!

1. Bought a .410. Have a Ruger 45 colt. wanted a matching rifle. I just do!
2. Don't want a mag to reload.
3.Yes I do as per question 1. looking for part 2
4.I ask because I am ignorant
5.Don't have any idea, never checked diameter of these. If you are being a smart aleck I don't understand the need to be!

Maybe we should just trade Spanky!

gcrank1 · « **Reply #29 on:** March 19, 2013, 07:09:25 AM »

A cheap 410 with no choke, equiped with sights or a RedDot or low power scope and the right sized roundball for the bore would not be too bad for small to med game and still shoot shot to cyl. bore capabilities (and, of course, the lowly 410 slugs). Stick 2 or 3 of those RB's in and it would be 'formidable'. No, it would not be a long range proposition, but at stalking ranges for pot & pan it would equal or better the old 'trade guns' of centuries past (the gun that REALLY won the west).
