Wondering about what kind of groups you guys have put together with factory stuff prior to building your own ? 150's-180's, doesnt matter..just wondering where to start to get that 1" 5 shot claim !

My Tikka 300 WSM will do it with factory Federal Premium 165 TSX and has shot several 300 yard five shot groups that were about 2 1/2". Thats where I would start.

great...whats the aprox. velocity/trajectory on that if you know ?

Fed Blue Box 180's is a rock star of a load for me! As well it's a fast load.

Federal premium 180 grain accubond does <1/2" moa in mine.

I have to agree on the Federal Premium 165 TSX. Ten elk so far,complete pass through,and 3/4 - 1 in groups out of a Kimber Montana.
