[QUOTE="MNbogboy, post: 762955, member: 18849"] Last spring I ordered a 6.5-06 8 twist barrel that didn't arrive till Jan of this year...Also after ordering the barrel I ordered a couple hundred 140 Berger hunting VLDs to break in the new barrel and related brass.... At about 150 down the tube I seemed to be getting real close to a good load at .045 off......Recently I received a second order of two hundred more....Base to ogive measures a full .050 more on an average with OAL length averaging about .030 longer while od is almost a half a thousandth smaller on the new bullets...Needless to say Berger's die change has created a new bullet for me and my load development has been re-initiated.....I am now seeing .005 off to .005 jam working better than the old bullet at 45 off..... Obviously we sometimes see a pattern of dimensional change from order to order as the bullet dies change with age...If we only could forecast when the manufacturer is going to make a die change, then we could probably make orders better suited to our personal need....In my case I would have waited and not wasted a $100 dollars on bullets that were one of a kind.
