[QUOTE="Hunterjones, post: 2288608, member: 112130"] If you have a set of Hornady bullet comparator gages & case comparator gages you can check BTO on bullets and see if there is a big difference and if bullets may be “jamming” into rifling AND if rounds that load tighter are LONGER from case head to shoulder than ones that chamber easier……if you have a minimum spec chamber, the second scenario makes absolute sense to me….. On a similar note to the different powder/large velocity variation in factory ammo, I’ve been working with a 6.5 PRC Browning LR Xbolt a friend just acquired. Accuracy with the 143 ELDX has not been stellar (1/2” groups to 3” groups) and some of that is due to about .020 BTO variation and about 120 FPS velocity variation. I have not been able to compare apples to apples because I can’t find any 143 ELDX’s to hand load but a couple of other bullets I have tried have had SD’s around 12 FPS and consistent accuracy around well under 1” [/QUOTE]
