Fixing to build another rifle in 22-6mm Remington and wanted to know what everyones thoughts were about this cartridge ...Going with a Shilen #5 SS-14 twist barrel. Going to be used mostly out the window of my pickup on Coyotes and other Varmints. Not really worried about the length, But open to suggestions. I know...Barrel Burner...I'm fixing to turn 56 in August and am not worried about this being a problem. 50 Grainers are the Go To with everything I shoot. Lets hear your input. Thanks, Todd

I went with the 22-243 and a 1-8", after a point you can throw a blanket over the lot, 100-150fps is just not enough to make a difference. You can use a short action, brass is everywhere and cheap. If you want Lapua is available, feeds great from a magazine, etc. Unless I had a LA I had to use........
Todd -
Howdy !
For info:
- You can run a .22-6mm reamer in "short " , to make a new .224" cal wildcat of more-sensible case capacity.
The reamer can be rented, if you don't already know a 'smith that has one.
- Base diam .466"
- Uses 7X64 Brenneke brass ( Norman, RWS , Hornady; Speer )
NOBODY that normally carries 7X64 brass....is out of these !
- .308 bolt face
- Utilizes 6.5X55 FL die as the " case forming " die. Expander ball and mandrel removed... to make the die
open-topped.
- Brass to be formed sits atop a " perch", made out of a .308 shell holder, a flat head machine screw w/ < .466" diameter; and two
jam nuts.
- In use, extra screw thread length is positioned in the press' primer arm slot in the ram ( example: "ROCKCHUCKER" ).
- With brass sitting on the perch.....press ram is operated, to advance brass up-into the forming die
- As shoulder is shoved down on the cases, excess brass extrudes out the top of the open-topped die ( example: LEE )
- Cases are first rough-cutoff, then detail trimmed.... to final case oal desired
- *** Cases emerge from the forming die w/ a nominal .224" neck ID . ****
- A .22 cal arbor is inserted into the case, and necks given an outside neck turn... to final neck wall thickness & OD desired.
This wildcat case ( off fore-shortened 7X64 brass ) is VERY robust, as it is formed out of the lower/thicker-walled portion of the parent
7X64 brass. Quality brass is available & at reasonable prices. I shoot a 6mm variant on 7 X64 brass, and cases have lasted 15+ firings, and primer pockets are just fine.
Non-custom dies are used for loading/re-loading, and the " perch " is NOT required ( for reloading purposes ).
In a 6mm variant that I shoot, I use a ( example ) Hornady " universal style " bullet seater die w/ micrometer top.
Neck sizing could be performed using a ( example ) LEE collet neck sizer body of correct length; and outfitting it w/ their .22calibre
" fingers", mandrel; and a suitable case holding " sleeve ".
The .224" cal wildcat described above, would have great case capacity for more-efficient use of that $$$ powder and bullets
Just a thought.

OK, I guess I need to clarify myself as to having a 22-6mm Reamer and all the equipment to build another one. I started out shooting this cartridge in the mid 80s after Rick Jamison came out with the 22-6mm CJ in Shooting Times. Now, That we have that cleared up, I am interested in anyone that has one and is shooting 50 Grain and Under Bullets. I could care less if its a Barrel Burner as I probably wont ever see that happen in my lifetime and if so, I will put another one together. I Love This Cartridge...Now, Let me hear from some people that have actually shot one or have one. PS, The other rifles I own have shot across my Pact at over 4280 out of a 28" barrel with a 14" twist just FYI...So much for the 150fps talk...Thanks!!

I just loaded up a bunch for a friend with 52 grain speer bullets, 150 fps is about what you would gain with this case over a 22-243, brass is easy to find, it probably is a barrel burner but who care's they sell barrels everyday just like bulletsTodd DuBose said:
Wayne.
I built myself a 22/244AI with an 8.5tw Bartlein blank last fall for out the window yote popping. All the yotes were insanely wild from the younger 'lets make some money this weekend' road hunters so didn't get a chance to see how well it worked! 
Shooting a 70VLD with 52.9gr of H4831SC @ 3660fps. Had it to 3740fps but groups went to almost 1" vs the 1/2"ish with the .6gr lighter charge. Haven't tried it with 50-55gr bullets but its gotta be nasty I am thinkin on a pdog or such!!! Went with the faster twist as I was looking for an out the window rig to 400yds where ranging first isn't usually an option or a running dog. Use a 6XC for the long standing shots and it is outstanding, especially if you can range prior because of drop with the 107SMK @ 3000fps being a bit more critical after 450yds or so. Not as nimble as I used to be and the pacer/defib and how I am paced makes them long unranged pokes out the window a bit more challenging as I get horizontal issues!
Also was hoping for a bit less recoil with the lighter bullet for spotting misses easier than the XC and 107's. However, my nievety didn't figure the 12.9gr extra powder charge and a bit lighter rifle along with the muzzle blast of a Hellfire making my 'rocket scientist' moment fruitless in the way of reduced recoil. So much for that brain fart.lol

So much for that brain fart.lolWayne, Thanks for the Heartfelt Reply!! I was starting to think all I was going to see and hear was 22/6mm Bashing. Like you said, They sell barrels every day and I have got to the age, If it blows up or burns up, Oh well...Do It Again!! I also have come to the realization about comparing Cartridges to women. What is better?? Short and Fat? Or Long,Lean and mean... I don't do Fat...We all have seen the WSSMs and the pros and cons on them. I for one don't have a problem with long actions and bigger cartridges. One of my main go to rifles just happens to be a 30/378 Weatherby 14 twist, 30" barrel with 125 Gr. Ballistic Tips. Best Coyote rifle going in my opinion. So, Now back to the 22-6mm....

Well there are pros and cons to everything, Like SD I have a 22-.244 ream I intend on using, same thing you have but in AI, so it's even faster, gonna do mine in a 1:7 twist and shoot 90 grain burgers in it out to a 1000 or maybe a bit further. I can't agree with you on the WSM's I have had my ass handed to me too many times by a fine tuned WSM at 1000 yards with the wind bucking capabilities of the 210 and 215 burger bullets, A friend of mine last month put 10 shots fired in probably 30 seconds or so at 1000 yards in 4.9" if I remember correctly and the winds were terrible, he did that with a .300wsm, best of luck with your new toy
Wayne
Wayne, I will agree with you on the Custom rifles but as far as I have seen with the Factory rifles the WSSMs pretty much are just that...Guess that's why we all like to go to the Lathe and redo Factory stuff huh? LOL!! I shot a 7/300 Weatherby for a Looong time before I started the 30/378 project with the light weight bullets. Around here, The longest shot at a Coyote might be 500 or so and I remember the Rams at Dietzs range at 500 meters hated the 125s. So did he!! Ha!! Couldn't knock them down because they would blow holes right through them!! I can still hear him cussing!! The thing I Love most about the 22/6mm with a 50 grainer is the Explosive part it does to whatever it finds in its path. Still looking for the loads from Rick Jamisons Shooting Times Article. If anyone knows of this, Please submit. Thanks, Todd
I am thinking of building a 22-6mm Rem. I have been playing with 53 Grains Sierra HP MatchKing in a sabot in my 308 Win and pushing them at 4669fps with 48 Gns of AR2205 also known as H4227, but I can not get better than 1.25 MOA groups. with a rifle that shoot 150 grain pills into .5 MOA. So I am looking a building something to replace my old 22-250 Sako Forester that I shot the barrel some 20 years ago. I was going to re-barrel it to 22-250 Improved, but have since given the action and stock to a friend who converted it to 308.
A freind of mine has one and loves it. The only thought I would put in your mind is that of a 1-12 barrel for the 53 grain VMax. This bullet will have a bit less drift and drop than any 50 grain bullet. They do not work in a 1-14. You will gain very little of anything by going fron a 1-12 to a 1-14, but a 1-12 will give you more flexability.
You should see a crow hit with a 53 Grain Sierra HP at 4669; I hit t in the breast muscle nothing left from the wings back and when we walked up to it it's heart was still beating. We had been deer hunting and we drove back to the camp crows were everywhere; feeding on the entrails from the previous day's kill. I poked the 308 (built on a M17 action with a Canjar trigger and a black mountain barrel) loaded with a 22 cal in a sabot out of the driver's side window and let loose on the crow that was about 40 metres away engrossed in the scraps of a chital we had shot the previous day. Wayne and Geoff yelled in excitement as it exploded, unfortunately I did not see the red mist and black feathers as the scope view did not allow it.
I just completed a build with a PacNor Barrel cut @ 27", 12 twist 3 groove, #4 contour, chambered in 22-6mm Ackley, shooting 55gr. Sierra Blitzkings, burning N150, formed the brass from Norma 7x57 brass. Several sub 1/2" groups, have some more test loads to shoot on Friday.. Another gentleman I know is shooting the 22-6mm Ackley with an MullerWorks barrel #5, 12 twist, 26", also with outstanding results.. Enjoy, Mike
I know this is an older topic, but just ran across it. I actually have the gun that Jamison built and shot in the 80's.. Haven't played with it in a while, and was browsing around for some loads that people are using these days.. Bullet and powder tech has come a long way in the last 30 years! I will report that my rifle still has the same barrel that was put on it for the article he did way back when.. it hasn't seen a ton of action since buying it. Best Original loads we shot out of it were using 4064 and 52 gr BTHPM. I just sized and worked up 100 rounds of brass last week, fixing to get it out and start shooting!
Todd - I am guessing with shooting at Dietz's you are around New Braunfels.. I have lots of family there. I have the hard copies of the original loads from that article at home in some reloading manuals.. I'll try and dig them out if you are still interested..

A day which we will live in infamy
I really liked my 22/6mm. Was an awesome rifle. Flat as all get out. Granted I shot mostly 75gr amax. I did load a few 52sierra match kings and they were about 4200fps. I only used retumbo. 49-53.5 is where I tested with both bullets
75 amax
75 amax
Hookem 74, I'm a Gonzales raised guy that enjoys living in the country. I sure would like to see a copy of the reloading for the 22-6mm. I'm in the process of trying the Gibbs effect as threading the primer pocket to accept a tube to start the powder from the front end. It really looks promising.
I have a 22/244 Ackley that is a 8 twist. I shoot Sierra 80 gr bullets at 3700-3800 fps very accurately. Have shot 1" (5) shot groups at 500 yards and 3 1/4" (3) shot groups at 1200 yards. This cartridge in my opinion is as big as you should go with heavy bullets and get much benefit. If I shot 55 gr bullets I would go no bigger than a 22-250 Ackley or 22-243 Middlestead. You receive little to no gain with mid weight bullets by going bigger.
I think the 22-284 sat a record for speed at one time. Over 5000 FPS. Matt
