thanks guys for the replys . it looks like i need a chrono to take to the range . i actually have one now but its wired for 110 so i only use it for archery work . and bobinnh thanks for the info on the 7mm mags . ive tried several slower powders and did not get the results i wanted as far as accuracy in both my 7 mags . i tried h1000 , retumbo , and 7828 but it could be bullet weights that i was shooting . i also tried rl22 and it shot good on 40 to 50 degree days and i went to shoot it on a day that 88 degrees and it was blowing primers out of the case so i stopped using hercules. i have shot the 4350 on days from 12 degrees to 90 with no issues so thats the only reason ive stuck with it .
