I have a 6.5 I stumbled on build by Selby great lighweight gun. I have only shot factory rem 120 core locts out of it not too impressive I know this gun is capable of a ton better. Any suggestions on loads bullets and primers. Was hoping to get 120's to 130's to shoot well out of it for packing in after blacktails. It has a 23" shilen so I hope to be around 3000fps. Someone mentioned 129sst, rl-22 and rem 9 1/2m primers i dont have any experience with any of these choices. My only reloading has been for my 7 mm STW using cci mag primers. Thnx
