I have two bolt action 223's including a Sako Varmint. I have two Win 270's including a Sako A7. I have 30-06, 7.62x39, and I have reloading dies for 7rm. Ok, here is the question: since my 223's shoot up to 55 grain well and my 270's shoot down to 100 grain well, why do I need a 6cm. Ok, I want a 6cm set up to shoot 80's to 90's. I don't even shoot the guns I have much. Why should I or should I not build 6cm? I might consider re-building my Tikka T3 270 into the 6cm. In fact that is what I should do except it is so darn light compared to the Sako A7 that I might want it on a long hike mountain hunt. They both shoot .50 to .75 MOA. Dang.
