22-250 vs 22-250 ai

[remington jim]

What your OPINIONS ? RJ

 

[CranePete]

Or .22 CM ? Just a different shoulder, isn’t it?

 

[Dogleg]

Less case stretch. That's worth something if you hate trimming cases.

 

[Gatehouse]

Had a 22-250 AI

It was kinda cool, very fast-but I don’t see the point of wildcats or AIs anymore.

22CM is a better option right now.

 

[remington jim]

You Know - I'm RE Thinking this and i'm NOW thinkin the 22 CreedMoor is the way to go ! RJ

 

[Jim870]

If the barrel is a slow twist I will take a standard .22-250 if going fast twist I may stay .22-250 but am only so inclined because I already have dies and an almost free supply of once fired brass from the range and friends. The .22 creedmoor is where I would go if considering improving it.

 

[Ganderite]

The barrel life of a 22-250 is about 1000 rounds, max. I went through 3 barrels before I accepted this.

If your application involves a lot of shooting, the AI does not work.

Most that get into the AI craze get over it and move on.You rarely get back what you've invested in brass/dies /gun.........etc

NOT a concern of Mine but thks for Caring ! RJ

 

[mbogo3]

I don't actually.

Would it be safe to assume the 22cm would have similar barrel life?

 

[Ganderite]

22cm is a slightly smaller case, so i assume will have better barrel life.

Ganderite, you must have shot those barrels mighty hot several times to wash the throats in 1000 rounds.
I have washed out several barrels, using "barrel-burning" chamberings [220 Swift, 264 Win Mag, etc] and
never had any done by 1000 rounds. My First Swift made it over 2000 before any noticeable deterioration
in accuracy appeared. This was a <.4 moa rifle, I even won BR Turkey shoots with it. One of my 6mm Rem
barrels went 2500, another made it to 2800. While I always shot full-house loads in them, I never shot more
than 5 consecutive shots without letting them cool down. I'M sure careful cleaning played a part as well. D.

Is your name Richard Head ? RJ

I think the 22 CM holds SLIGHTLY more powder at 52 grs case capacity ? RJ

I was shooting 80 gr Sierra bullets. 30" barrel. I could get 3400fps, but did not load that hot. I used moly bullets, too.

Around 1000 rounds bullets would start to blow up about 40 yards in front of me. I could then down load to stop the problem, but then I was getting 223 performance. I was using quality stainless barrels. a blue barrel would be worse.

I would fully agree with this.

Interesting. Isn't that sort of behaviour caused by the rotational forces? Seems odd to me that they would be fine for a while but then start coming apart after a certain number of rounds down the pipe?

I recall Douglas having this issue with his 22baboon build (22-284 I think it was?), but it was happening with a fresh barrel.

 

[todbartell]

22cm is a slightly smaller case, so i assume will have better barrel life.

22cm holds 52.0grs H2O (Alpha) and 53.3grs h2O (Hornady)

22-250 is around 45 grains +/- depending on brass/chamber

 

[dan belisle]

have both versions of 22-250. AI is faster and the brass stretches less.I doubt there's much difference in barrel life between the two. - dan
