What reamer did you end up going with?

I think that's where mine came from.

Took the rifle out last Saturday . Shot it at 946 yards, all bullets (147 ELD-M's) made it to the target. Shot about 2" elevation. Used a G7 bc of .316, 3090 for velocity and 6.0 mils for elevation. It shot .4 mils flatter than a 300 PRC using a 208 Hybrid target at 2880 fps.

Thanks! Impressive results

Took the rifle out today and chronoed it. Developed the load in 85 degree heat and the load was at 3100 fps. Today it was 25 degrees and chronoed 3077 fps. At 85 the ES was 1.7, SD .7 . At 25 ES 9 SD 3.8. Both 3 round strings.

Have a Manson reamer if anyone is looking

Thinking about doing this myself. My 6.5 PRC barreled action is currently at Kampfeld getting cut down from 24” to 20”, and I’m contemplating having him go in with a reamer, if he has one. It’s a Sako S20 so removing the bolt stop should do the trick for the longer cartridge. Anybody want to talk me out of this?

I’m still on the fence of doing this with a take off creed barrel or just building a 6um ahh tough decisions the lower recoil with the 6 um sounds better at the moment tho

I've been playing with a 6.5-7PRC lately. It seems cool enough. 10 more grains of powder for 150-200fps over a 6.5 PRC. That's just how the overbore game goes though IMO. Big increases for small gains. But it seems like it'll be solid. I just ordered a 26" barrel to shoot 156's possibly with N570 when the lapua brass comes out. Saving that barrel for a new lot of brass.

Currently have a 22" barrel and headed out soon to do a pressure test with 156's and H1000, N565 and N570.

I shot the 140 hybrids comfortable at 3100FPS in my 22" barrel with 68gr. H1000 and a 210M.
