My brother had a 6-284. i do not know what other bullets he tried. the bergers reached the target about 60-70% of the time. Quite disappointing when you are in a match. .

    Wrong bullet for twist.

    Which Bergers are these that didn't make it to the target but 60-70% of the time???

    Has he tried the new 105 Hybrid Target because they are working very well in my dads 6-06AI and they have the best BC of all the 6mm Berger bullets. In load development he was driving them well over 3600fps and they made it to the target just fine.

    Shooting 105 vld in my 6-284 at 3250 with no problem and pushed them up to 3400 and they were all making it to the target. Same with 105 amax. And it's an 8 twist

    Thanks Z. I spoke with Hornady today and was told 300,000 rpm was the max they recommended for the Amax. 3300 fps with an 8 twist spins just under 300k. So I should be ok with the Amax, as I don't plan to run more than 3300 fps.

    The original berger VLDs, I think they call them 'hunting VLDs' now, would come apart right where folks are suggesting here. The newer 'target VLDs' have thicker jackets to address this specific issue, and apparently with success.
