Have a new A bolt on its way,along with some 180 bergers . I am having a hard time finding much load data for this . Can some of you supply what loads you are having good luck with. Thanks

Go here: 7mm Cartridge Guide within AccurateShooter.com

Go to the Berger website and email them. They will send you load data. Or you can pm me your email address and I can email what they sent me for the 140, 168 and 180 gr bergers too you.

what is the barrel twist of the A-Bolt?

 

[Enzo]

1/10 twist. I emailed berger on Sun no reply yet.

 

[HoytFlinger]

I think the 10 twist may be too slow for the 180s. Berger recommends 9 or faster. See attachment.

Does that mean bullet will not stablize , bad accuracy? Already ordered 180's but my brother has some 168 bergers for me to try also.

 

[HoytFlinger]

Yes, it could very well mean bad accuracy due to stabilization issues. Try them and see. You never know with factory barrels. I would almost lay money though that the 168s will be much better than the 180s in that rifle.
