[QUOTE="4xforfun, post: 423810, member: 9172"] I just re-inspected my brass with a magnifying glass....there is a very slight cratering of the primer at 88 grains which was not evident with the 87 and 86 gr loads. I can just feel it whith my fingernail if I concentrait. Now obviously the primers are flattend some, but they are all the same from my starting loads on up...identical. Like I said...I think I am getting close to the end of the line, speed wise...and with 1/2 moa 5 shot groups before the final "tweaking" I should be ok, accuracy wise. I will do some final testing when it gets colder, although the gun is in my heated "blind" (for lack of a better word) so extream cold temps probobly won't be an issue. [/QUOTE]
