FINALLY got my 260 together.

[FW Conch]

kingzero, I know all rifles are different and like different things, but my 260 loves 43grns of IMR4350, 140grn PSP,CCI BR Pri. Hodgedon lists only a max load for this at 43grns, 2715fps, and only 57,000psi, so I went with it right off. No pressure signs. This combo shoots bug holes at 100yds and 1/2 Moa out to 300yds for me. I could easily be wrong, but I doubt your issues are coming from the IMR4350. Off hand, I suspect your not using enough of it. O yes, the 140grn PSP is a "bore ryder" bullet, and this makes it easy for me to start it "touching" the lands, which I think helps this combo. Good Luck-Good Shooting........Jim

I am shooting 140 SMK's and worked my way up to 42.8 grns where I saw slight flattening of the primers. I feel I could take it to ~43.2 grns but nothing above 40 grns printed worth a ****. I was running .002" off the lands.

King have you ever used a suppressor before? Could it subtract accuracy? Dunno just asking.

Don't think so. Accuracy was great with starting loads. I just don't think my rifle likes the higher charges of IMR4350.
