Guys, I am thinking about building a 22-6mmAI. I am thinking a bartlein 1-8 twist barrel at 26-27". I know you can use 6mm cases to get there. What about the 224 TTH? Would that not be a better case to start with? Already necked down, just have to blow the shoulders out to 40 degrees. Also I have searched here and elsewhere for load info. Most is for standard 22-6mm, not the AI. Looking at the big Bergers 80-90grain for this rig. I like the bigger bullets for long range shooting. Any help/advise would be appreciated. Mark

Might be a little overbore...

What about a .22 caliber on a 243 case? Quality brass is very easy to acquire.

Might be a little overbore... Only in a short action. Personally, I wouldn't think of anything more than a 22-30mmAI, full length of course, to avoid that overbore issue. Ed

About 20 years ago me and my nephew tried about every 22cal possible. we tried a 22-284 that is just slightly larger capacity than a 22-6mmAI........you will never get the speeds you think you will and the barrel will be half shot out by the time you work up a load. Biggest I will go ever again is a 22-250AI with 1-8" twist. about 5 times the barrel life and you give up very little velocity.

I always wondered if the 22-6mm would be almost the same as the 220 Swift.

If you have access to Wildcat Cartridges Vol. II from Wolfe publishing, check the data for the .224 Clark. Dimension drawings show it is a little longer to the neck/shoulder junction (11.933") and a little fatter at the shoulder (.455) than Hornady's drawings for the standard .22/6mm; it has a 30 degree shoulder. I don't know the dimensions for the .22/6mm AI, but I'd suspect they are close enough for starting loads.

They have a 5.6x57 in Europe! Be about the same thing.

The .223 WSSM has just about exactly the same powder capacity as the .22/6mm, and I've used .223 WSSM data in a .22/6mm with just about identical results, though obviously that would depend on the throat length in the .22/6mm, plus throat wear in either rifle. But the main point is that .223 WSSM data is a good starting point for the .22/6mm AI.

Thanks for all the info. I will be sending a long range Remington to Pac Nor for a new barrel next year. Always like the oddball stuff. Have a Merry Christmas all.

I had a .22-6mm made up in a 26" barrel, and my experimenting has lead me to using Norma MRP with 75 grain bullets. I still cannot manage less than 1" groups at 100 yds, though...not impressed thus far.

My .22/6mm had 24" 1-8 Brux barrel, in a heavy sporter contour. It was easy to get to get 5-shot groups inan inch with several bullets, and much smaller with some. But it absolutely hated 75-grain A-Maxes!
