[QUOTE="MNbogboy, post: 1068306, member: 18849"] I also have found Nosler (ballistic tips) & hornady (Amax) to be very consistent from lot to lot and normally do not have to adjust...[knock on wood] Berger bullets (they are accurate) are all over the place from lot to lot and year to year... Sometimes I found base to ogive as much as .015 different and rework had to be done...Don't know if this is an actual change in the profile or their dies or die manufacturer are just that inconsistent....I have had older 130 grain 6.5 hunting bullets that were actually longer in overall length than 140gr 6.5 hunting but weight consistency was superb.... They however are usually very accurate when tuned back in.... Not only does base to ogive change but diameters also increase as the dies wear... which also affects bullet overall length which again can cause feed problems after adjusting jam/jump....Diameter changes usually small (a couple of ten thousandths up to .0005) will obviously affect velocity & pressure.... Don't know if these changes are deliberate as a marketing tool to sell more bullets because of extra load development or possibly a result of manufacturing lax and QC....I have used .243, .257, 6.5s and .308, after purchasing literally 1000s of Berger bullets and seeing some of the problems I find them very accurate once tuned in so my suggestion is to purchase as many as you can afford of one lot at a time...This goes for all bullets....
