Built this rifle for a friend of mine. He wanted a lightweight rig for a Marco Polo Hunt he has in a couple years. LPA Fuzion Ti action, Proof 1:9 @ 24”, Manners elite T5, Triggertech primary. Running 215 Berger’s @ 2920 over 77.1gr of RL26. Got an ES of 7 FPS at .100” jump. Groups .5 MOA @ 100 but the only two rounds fired @ 735 yards grouped as below. I’m very happy with how it turned out.
300 PRC promising results.

SAAMI spec'd reamer or other?
Reason I'm asking is, I know 6.5PRC had issues with different freebores from the saami spec. I have a 30 cal barrel on the bench I'm going to chamber in PRC. Just researching what freebore I should go with for Berger 212's.

I’m pretty sure the bare spot on the right is an impact. Target rang on both shots. No other impacts on it. Here is a single shot on the preceding target @ 540 yds.
Both of the impacts from the first image were centered up nicely, a little above center, just like this one. I don’t think I was clean off the target but I suppose it’s possible tho. Rifle needs more rounds down the tube to confirm but as I said, early signs are promising.
Great looking rifle. A Marco Polo hunt is my bucket list hunt. I hope everything works out well for him!
Sammi spec chamber using berger 215s with a CIP magazine are not an issue. Mine are at the lands at 3.727 COAL. I load them to 3.707 and they work well.
They will fit fine in a mag box yes but you are leaving a lot of neck unused doing it that way. That was much less of a problem with the 230’s, much shorter ogive. 210 ABLRs were the same way. I probably should have clarified that.
You will most likely speed up with that load and the 215s after you get more rounds through it. After the first 80 rounds I sped up 50 fps. Now at 76.9gr Rl26 in a 26 inch tube I get 3018 fps with the 215 Bergers.
All good. Here is a pic for reference. Looks about .060 ish. Eyeballing it.
Sweet build though. Your buddy will enjoy that thing.

How far back did you seat yours in load development? I took mine all the way back to .120” jump. Best was at 100 off for me. Groups were smallest there too, however shooting for small groups with a lightweight rig burning this much powder isn’t the easiest thing I’ve ever done.
Only the 20 thou off after my "at the lands" pressure ladder test.
Shoots under half inch 5 round groups with single digit SDs so I didnt need to do anything else with it. 400 some down the pipe and going strong.
