22-06

[ksp500]

I am wanting to have a 22-06 built. Does anyone have any data or experience with this round? Would a 6mm-06 be a better choice?

[cwlongshot]

First and foremost, WELCOME!!!

 The 22/06 is serious overbore and I look at it as highly specialized and near worthless to the average shooter. Barrel life would be short and if you loaded it back why have it?

The 6mm/06 is still overbore but more common. It would in essence duplicate what you get form the 240Weatherby. I have repeatedly herd that the weatherby data could be used for the 6mm/06.  PLEASE CHECK and confirm that before loading!!

 What is your platform& intended purpose?

I have thought about the 6mm-06 but they say the barrel life is about 1000-1500
rounds.
I would think the 22-06 would be much worse than that.

Barrel Life: This is a gray area that I won’t spend too much time on. The 6mm-06 is an ultra-fast cartridge with a lot of powder going down a little hole. I’ve always said it takes about 2.5 seconds to burn out a good barrel, and with a 6mm-06 I think I’m right. (.0025 seconds X 1000 rounds = 2.5 seconds)! A lot of varmint hunter and wildcaters view a barrel as a temporary attachment and to me the performance is well worth it. You’ll have to decide that for yourself. My experience is that with proper cleaning and shooting techniques a 6mm-06 barrel will last somewhere between 1200 and 1300 rounds.

I am looking at a remington 721 for the action. I am wanting a really fast coyote popper. I realalize bbl life might be 7-800 rounds if properly taken care of. What kind of velocity with 75-80gr bullets??   ksp500

[Kurt L]

with the 6mm-06 he shows 3800fps for 65 v max

I always thought the 22-08 was the 22-250 and the 22-06 was the 220 swift. Is this incorrect?

Ed Panzella

Nope,

The 22-250 uses the 250 savage case necked down and the 220 swift the defunkt 6mm lee case again necked down.

[ksp500]

What do you think the best bbl length would be for a 22-06? 24", 26" or 28"??  Is the 22-06 Easling the same as the 22-06?   ksp500

Sorry I do not have any info on that.

Thanks for all of the info. I'm gonna do some more research on the the 22-06. Something about it just says build it. I know it won't be practical but I think it would be a lot of fun to shoot and maybe bragging rights at the range. thanks again for the info  ksp500

What about a 223 wssm. Current factory production so no stepping down brass. I'm running it at just over 4000 fps with 55 gr. Has benchrest accuracy, wich the 06 wildcat does not. Also a 243 wssm is available. I have about 1200 rounds through an ar, still holding one hole groups. Just finished a 243 wssm will be about a week before I get the optics mounted.

[trotterlg]

I was considering a 20-06, I have a Remington 204 take off barrel to play with, and a 25-06 S&W I-Bolt to put it on.  I was thinking about 35gr bullets at about 5,500fps.  Larry

Are there any thick jacketed bullets in the .20? My 223 wssm shreds the jackets on varmint rounds. Have to use sierra gamekings or it is a mini shotgun. Same thing on 223, varmint grenades and 1-7 twist.

[trotterlg]

The barrel I have is a 1 in 12 twist and 24 inches.  I would think there would be the same type of problems with a 22-06 also, except you should shoot solids i it and eleminate the problem.  Larry

I talked with one of the experts at Hornaday when starting to develop loads for my 6MM-06. He recommended using VihtaVuori powder. He said it would get better velocity with less pressure and that seemed to be my experience. I now have two 6MM-06 barrels to fit my Thompson Center TCR-87 rifles. For my 29-inch slow twist-barrel, 61.0 grains of N560 gives slightly over 3,900 fps with the Nosler 70-grain Ballistic Tip. For my 26-inch fast-twist barrel, 54.5 grains of N560 gives 3,300 fps with the Berger 105-grain VLD bullet. I could get around the same velocity with the 105-grain bullet with IMR 7828, but accuracy was bad and velocity was inconsistant.

'06 is old. 1903 first standardization. Redone in 1906. Since there has been tons of "improvements." Changes that seem to contribute to better accuracy/performance. If you think you have to go this far "over bore" then necking down the .284 case ... it has the short powder column, same size as '06 approx; and the sharper shoulder... Most of these rounds got started from all the free brass that uncle sam left lying around... If you happen to have a couple thousand left around... (When I was young, I had to pay $0.05 per round for surplus... awwww).

The .240 Weatherby Mag is just the '06 case with a belt necked down to 6mm. (Double radius shoulder, of course...). It is in most of the books for comparison. 6mm gives you a slightly heavier and more ballistic efficient bullet... Important.

.22/250, as said, made from .250 Savage case. 6mm version called 6mm International.

.22/.308 is done again and again. Dashers, shortened .243 case, one popular now. Google it. Yes current "hot number" is 6.5x47 Lapua. Compare it to the .250 Savage Improved in either .22, or .24 or 6.5... Not a dimes worth of difference. No doubt Lapua makes fine brass. Happy new year. Luck.

Hi
I have a 22-06 and a 6mm-06 both shoot nice groups. But I have flash tubes in the 6mm, which lights the powder from the front and which burns back into the case. The 22-06 I use a slow ball powder (H870,I think) I shoot both, they are built on 03's. I do not shoot them with a hot load, just where they grouped. The local gunsmith built 3 of the 22-06's and Shilen built the 6mm.

[hillbill]

jimann, please explain the flash tubes yu speak of for those of us less knowledgeable?i realize it is probably a way of igniteing a large charge of powder more evenly but i am not familiar.thanks!

[jimann]

Hi
     I will try! I did not invent it. You start with a fired case, you drill out the flash hole and tap it from the front. It takes a weird tool to keep the tap centered to the neck. Then you take a thin tube ( I bought mine from the guy that showed me how to do it) so, I do not know what size tube. You cut the tube 2/3 the length of the inside (they should all be the same length) and then you thread the end of the flash tube. Next you cut a slot in the other end for a fine screw driver. To install the tube you need a tool (another slightly larger tube) the flash tube goes into the tool (tube) and the screw driver into the other end of the tool (tube), Put a little locktite on the threads and screw it in to the threaded flash hole. Let the locktite set up and use a primer pocket uniformer to square the bottom of the tube and prime pocket. You now have the case but once you shoot it you need a tool to get the primer out. It is another tube that slides over the flash tube, but it has a length of spring steel wire sticking out the end, to deprime the case. I have yet to figure out how to clean the case. The flash tube fills with the cleaning media and is tought to remove.
     Lots of work but it really helps an over bore case. It also made both of my rifles shoot better! The only problem I have had is picking up a freshly fired case...They are hotter as most of the powder burned inside the case.
     There are several reasons for flash tubes. The main one being Overbore, rather then shoving burning powder down the barrel. Most of the powder stays in the case and gas goes down the barrel. But it does help with the accuracy, in both of my rifles, rather then burning the thin column of powder(diameter of barrel) you burn the powder in the large case. And it keeps you of the streets working on the brass.
     PM me your address and I could mail you a case to look at, I tried it first in a 30-06, to see if I could do it, so I have those that I do not use. It didn't really help. At least I couldn't see it.

[Totenkopf]

Jim, this is a neat concept. Even though I wouldn't take the time to go through all of that personally, I like it. It is perplexing to me though. Let me see if I get this straight. The tube would have powder in it too right? So it would ignite the thin tube but leave the majority of the powder colum unburned at the base. So it would light the 1/4 towards the bullet first initially. Then run back towards the primer to completly burn the volume. So in essence instead of an explosion, from the primer forward. It is performing and implosion from the bullet back? At least close to the bullet anyways. Are there any links to these setups or pictures online? It just boggles my mind to try and comprehend the concept. I really don't like magnum calibers or overbores. So no need for me to build a setup like that. I'm just a gun nut and interested in the topic.
Thanks

The flash tube described is old school to the max, dating from the 1860s (http://www.google.com/patents?vid=USPAT5090327).  Even wildcat experimenter Elmer Keith used the technique until he confirmed that it was not needed with modern powders, especially considering all the trouble.  Every decade or so someone re-discovers the flash tube and goes to all the trouble to mod his cases - for minimal if any real gain.

How it works:  the tube is empty of powder and does nothing but transfer the primer flash to the front of the case - hense the term front ignition.  The theory was that the powder burns better if ignited in that way. But in normally-ignited cases all the powder burns before the bullet travels more than 2 inches anyway.    Most (but not all) modern ballisticians discount flash tube use for these reasons:

- the tube takes up valuable space in the case, reducing its capacity
- the tube changes the shape of the powder charge, not to the better
- the tube absorbs heat from the primer flash, reducing its effectiveness in igniting the powder

Net gain zero at best.   But if it floats your boat I say fine - it's another thing to tinker with.

I do not have a .22-06, but have a .22-6mm so I am close. Mine has around 1,000 rounds down the tube and I have not had to start setting out the bullet yet. It has an 8 twist and is a tack driver with eather 80 gr. Sierra`s or 80 gr. Bergers. Don`t worry about burning out the barrel hunting coyote or similar. It would not last long shooting PD`s or punching alot of paper in a short while though. In the .22-6mm my present load pushes an 80 gr. bullet at 3,250 fps. I can push them to 3,550 fps. but have not been able to get tack driveing accuracy above 3,250. With the .22-06 you might want to go with a 7 twist and shoot the 90 gr. Sierra`s.

25 yrs. or so ago I built a 6mm Gibbs, blown out 06 case with sharp shoulder and short neck.  Tried to get the velocities that the inventor, Rocky Gibbs, claimed but never did
and after not more than 500 rnds. there was only a trace of rifling for 2 or 3" in front of the chamber.  My advice is get a 22-250, it'll be more accurate, no $150 dies and it'll kill coyotes as far as any .22 you'll design and far a lot longer time.

Have you looked at the 22-243 middlestead. It is a 243 win necked down to 22 cal. I am a 22-250 fan or this would be in my safe. http://www.reloadbench.com/cartridges/w22243m.html

Have you thought about a 224 Texas Trophy Hunter? It is based on a 6mm rem case which would not be quite as overbore and would increase tube life a bit.  You could form brass from 6mm rem or 7x57 or 257 Roberts. A buddy of mine has one that has had almost 1000 rounds down the tube with no loss of accuracy yet.

[Steve P]

20 and 22 bore with 06 brass.  Extruded powders.  I can only imagine how long it takes to get the powder down in the case.  Guess you wont be shooting 100s of those in one sitting, unless you have lots and lots of time to reload.

Here is the results of my choice in a max bore .224 wildcat. Velocity is 3,670 ft/sec. Bullet was moly coated.

[jelsr]

Not throwing rocks but this sounds like my 17 Flintstone (22-250 necked to 17) It was a hoot to shoot, prairie dogs would drop just before I pulled the trigger. 38 gr of H870 for a 25gr bullet just isn't practical when they have cartridges that will virtually duplicate the performance with far less powder. Cool for bragging rights but otherwise it's like a 10 lb yo-yo.

i think it is called a 224 Clark
I met guys in Idaho that hunted bear with them and swore that bears dropped like rocks
I was dropping them with a .41 mag revolver back in those days
