PS: Packing peanuts, they will bust you just as fast as stripper glitter- ;D

[/quote]..................... Been there done that ::) Leonardo, I've been shooting the 123 smk w/ 37.5 to 37.7 grs RL-15 w/ the fed. 205M's. Lotsa powder fouling. Switched to CCI br-4's last range trip. The br-4's cut powder fouling by more than half. (no change in powder chg wgt) 3 & 4 shot groups 3/16ths to 4/16ths letting the rifle "free recoil" using bi-pod and bunny ear rear bag. SMK seating depth = touching lands +.001"..... I'll probably use 82boys advice of mag primers & compare results. Note: this load was safe in my rifle. I've read of some shooters reaming flash holes larger on Lapua 6.5X47 brass. So there may be some "magic" in the hotter primer, larger flash hole idea. Good luck w/ your project. Dale
