a gain twist barrel is easier on jackets than constant twist rifling.
Having built alot of 338LAIs this last few years, agree with Daves observations.
Personally I have had phenomenal success with 9.4 twist Rock Creek barrels.
We use them consistently out to 2400 yards with great success when shooting 300 gr SMKs or 300 gr Scenars. If and when Berger or Hornaday get there stuff on the shelf we may have to revist the twist rate issue.
