CritterGitter Report post Posted August 12, 2015 I was making up a batch of ammo using 180 gn accubonds last night for my 300 Win Mag. I had to open a new box of bullets and when checking measurements, noticed that the ogive on the newer box was 10/1000ths closer to the bullet tip than the previous box. Has anyone else experienced this and do you have any idea how it might affect the ballistics? i reset my dies so seating depth is where it's supposed to be, but this doesn't make me confident at longer ranges.

10Turkeys Report post Posted August 12, 2015 Common occurrence with pretty much all bullets, check the numbers on your old box and compare with the numbers on your new, probably two different lot numbers. Most competitive shooters will buy larger quantities and all the same lot numbers trying to avoid such happenings. Share this post Link to post Share on other sites
STOMP442 Report post Posted August 12, 2015 Just keep your C.B.T.O. the same so you are not jamming anything into the lands or keeping the same amount of jump. 10 thou seems pretty excessive but shouldn't change things much if it at all. Load some up and go shoot them is really the only way to know for sure. Share this post Link to post Share on other sites
