22-6mm , and 75-80gr a-max.

Has anyone had a play with a 22-6mm,
I was thinking about getting a fast twist 22-250, but as I have a bunch of 6mm rem brass, and a spare M700 long action, am having sum thoughts, about the 22-6mm, what can I expect for barrel life, ?
what twist 1-8 ok for the 80gr or should I do 1-7

It will be built as a light weight hunting rifle, used on feral goats and smaller deer, have got onto a hunting block that is infested with goats and pigs, and has a few fallow deer, its very steep, and most shooting will be long range,300-500m, across gulley's, hence wind is a problem. thus the reason we are looking at high bc bullets.
I have been using my 2506, and my .243, but the .243 isn't really accurate, and the recoil and noise and cost, on the 2506, is excessive to cull a 100 plus game in a day.

has anyone used the 75-80 gr amax on game animals up to 120lbs on the hoof,

I am in New Zealand right now, due to the oil patch slowdown, so I don't want to hear anything about you opinion's on a .22 cal for deer, it will be a wasted effort, as I used a .222 for deer/goat culling for several years, and are well, a wear, of the benefit's and limitations.

What you are basically describing is a fast twist 224 Clarke. I have one, quite accurate. I'm not sure you'll get a lot of barrel life, but it will certainly do the job. - dan

Sounds like the 22 Express from about 100 years ago. Not sure I understand the 22-6mm compared to just staying with the 6mm.

Less recoil, cheaper bullets. - dan

The 75's will work for what you are looking to do. Case capacity in the 22-6mm will work well with the 1-8.

You won't need a 1-8 twist to use 80-90 gn bullets. I did this in my 22-284 and I'm smoking bullets at 3700 fps........puff of smoke at about 30 mtrs out and no holes in the target. After some research I found that at my velocities a 1-12 twist will stabilize 80-90 gn bullets so in the 6mm case not AI'd I would stick with 1-10. The 22-250 will use 80 gn bullets at about 3300 fps (IIRC) in a 1-10 twist, according to the article I read in Handloader.

I've got a 1 in 8" twist barrel on a Remington long action 700, chambered in 22-6mmAI. I use 75 gr A-MAX bullets and was using Ramshot Magnum powder but will have to switch to R1000 or Retumbo as I am out of Magnum. The rifle is very accurate to extreme yardage. No bullets smoking from this one.
