[QUOTE="sbruni, post: 1730557, member: 27945"] Have been working on a load for a new 6.5 PRC and settled on a pretty good load with RL26 that's pretty consistent .5 to .7 MOA... In the process I had some test rounds that were a little hot so pulled the bullets with an impact hammer and charged them with my final load and reseated the bullets... Now I usually use these as fouler thinking that the neck tension won't match the rest of my brass... This time I had enough that I thought what the heck I'll see if they group with the rest of the fl sized once fired brass... So the .098 MOA group that resulted has my attention.... I'm thinking there might be something to Mandrel sizing.... So a few questions for those that have experience with mandrel sizing the ID 1) who's mandrels do you use (stainless or TiN coated)? 2) Do you inside lube before? 3) Do you used the expander Mandrel? Or Turning? 4) what relative size Bushing do you use? 5) Any other keys to success? Thanks in advance for your help [/QUOTE]
