Right now I shoot a 7mm sendero(350 shots thru it) and I get consistant 4"- 5" 5 shot groups at 670yrds I also just picked up a 7mm 700P and it shoots the same as the sendero (60 shots thru it) Question is! if a guy does the neck trimming, tention thing and gets the bullet coming out of the cases straight, realistic what would the group size go down to? right now I use the RCBS standard dies and I just reload! No case prep other than chamfer and bevel necks! I am thinking about going crazy on the redding dies, gauges etc Thanks for your advice,comments, and those that have been there done that! who might would maybe save me a lot of time and money!
