[QUOTE="elmerdeer, post: 145109, member: 7381"] -------------------------------------------------------------------------------- I have a few questions for you guys to answer, 1) Does seating the bullet .005 off the lands change velocity as opposed to seating .020 off the lands? 2)Does a light crimp make velocity slower as oppossed to no crimp? 3)I shot some reloads with my 7mm rem the other day, it was -15c or a 5f (cold) my loads were RL22 66.5gr with 140 accubonds out of a 26" barrel,Sauer 202, my average speed with these loads was 2975fps.The Nosler book list that laod at 3240fps with a 24' tube, WHY THE BIG DIFFERENCE does the cold affect the velocity that much or is my barrel a bit slow? It is a new gun this was the 2nd time at the range with it. Sorry for all the questions guys Thanks Elmer [/QUOTE]
