[QUOTE="swampratt, post: 3283332, member: 15054"] Yes i am saying Varget is not the group holder when temps change. May hold velocity but groups scatter. IMR4064 does not do that in my .308 or 30-06. 8208 Holds together but velocity is low. blake711 were those 62 gr Hornady bullets a flat base by chance?? Or much wider base than the other bullets you were playing with. I have found the flat base is very accurate and easier to fing a load for. Some of the boat tail high BC bullets I played with wanted to be in the upper load data area and curse me for saying this but past some book data loads the high BC bullets really tightened up. This held true for my 30-06, .308 and my .223 I never got into high BC bullets for my .243. Just stuck with Hornady 87 gr V-Max in that one. Something else along the lines of bullet shape I went to the trouble to measure bearing surface length of different bullets. The ones with long lengths would stabilize easier ,,in other words low accuracy and high accuracy nodes were easy to get and were pretty wide. The short bearing surface bullets wanted to go FAST..Those were usually high BC bullets. [/QUOTE]
