What y'all using?
I've got a stainless action with criterion heavy barrel, braked. B&C stock.
I recently installed a CDI aics bottom metal.
Wanted to see how it did with some federal fusion 120 gr.
Catastrophic results. 3.5 to 5 moa. Never thought different bullet weight would make that kind of different. Went back to federal factory with 142 SMKs and it shot it's typical. 5 to .75 moa.

What bullet weight does everyone here use for their 260s with 1:8 twist? Wondering about the 147 eldm if anyone has any experience. Obviously this gun with be used for match/target shooting.
