[QUOTE="Buffalobob, post: 210251, member: 8"] I do not own a chronograph that way I can make up any velocity I want to and not be lying. Kirby chronographed it at 3340fps with 102 grains of US 869. I am now running 103 grains with fully formed cases and I believe it is about 3350fps. It is a four groove 34 inch Lilja barrel. Kirby now uses Rock 5Rs with thin grooves and he can reach the same speeds with a 30 inch barrel I believe. I think Dick is using a 32 inch Rock barrel At 54 & 78 degrees at Quantico which has an elevation of about 200', I got drops of 17.0 - 17.5 MOA at 1K. These are real fired data, not calculated. The data are the reverse of what you might believe because I kept the bullets in a cooler in the warmer weather shooting so the bullets were actually colder. Powder temperature at the time the firing pin strikes is pretty important at 1K. [/QUOTE]
