I would caution anyone who used up their supply of 200 gr accubonds that they acquired several years ago, that a new bullet might be different than the one they used in the past.
This happened to me. Pet load with newer bullets was terrible. Went through rifle thinking it was scope, bedding, crown etc. Called Nosler and they said OH YEA WE CHANGED THE DESIGN OF THAT BULLET.
It has happened to me with Nosler THREE times and Barnes so many times I quit using Barnes bullets. FYI Sierra never changes their design if they do they will assign an different product number. Berger has changed very few of their bullets when they first came out. To be honest the only one I know of is the 338 cal 300 gr due to jacket distortion but to my knowledge once redesigned it never changed.
Thought I'd share.....
