22BR barrel length

[SpencerC]

Well, I think I've decided to go this route, over much debate. Now, the question is, are you seeing any real velocity gain from 28" to 32" barrel length? I know the .223 doesn't really gain from going farther than 28, would the 22BR? It will only be slinging the 90gr VLD's. Will also be trying one of the variations of the "canted rifling" that claim higher MV, better cleaing, potentially longer barrel life etc... Any truth to these claims?

Was thinking mostly Broughton, just because they can do it with a 1-7" .224, shilen only does 1-8" and Kreiger doesn't go below 6 or 6.5mm.

Also, chamber dimensions, I don't want to mess around with all that neck turning s*** , so .254 should be good for a no turn neck, correct? All help appreciated.

Cheers

My 22BR is a varmint gun(14 Twist) with a 28" Krieger barrel.

I can`t help you with velocities because thats the longest barrel i`ve had in the rifle....

As for a no turn neck....make up a dummy case and measure a .254-.255 should work.....

Built quite a few of these...standard specs are 28-30" barrel (All Broughton 5C's- yes, the claims are true) running the 90 Bergers anywhere from 2800 to 3100. I am currently breaking in my new barrel on my BR rifle and I am getting 3050 to 3100 with N150 or Rl-17.
Reamer is a 0.254 for no turn...
