300wsm

[daka]

I have Sako 75 in 300WSM and would like to know best weight for my r.of twist.
I never could get a constant group without a flyer.
Had really good succes wit R17 and Barnes TTSX 168gr 65.5gr
I had 1/2" in 4 out of 5 but 3 or 4 bullet would always be another 3/4or an inch right...
Cant understand this pattern.trying to stick with factory COaL just to make it easier for my self when trying different loads.

I have a 300 WSM and consider it an inherently accurate/easy to tune round.

If it's always to the right, I'm inclined to think it's not the load.

Thinking calm and waiting at least 2 minutes between shots. See if it goes away.

If you are not, use foam plugs under muffs at the range.
