Curious if anyone is using this cartridge for long range shooting with good success? I am interested in a 6.5mm cartridge. I originally was thinking 7mm but brass quality is a concern. I see lapua makes brass for this caliber and that has me interested. I have done some reading and it has a long history, just not sure how it stacks up against the newer 6.5 cartridges. The rifle would be a tikka t3 hb varmint. Not interested in hunting, just paper and steel.
