Jumped on the 25 Creedmoor train this spring for my PRS build. Starting to really get it tuned in, struggled with LRP brass for a bit. Do yourself a favor and start with Alpha SRP. I bought 6.5 Creedmoor and necked down to 25 cal. I've settled on H4350, 42.1 Grains gives me 2970 FPS and phenomenal grouping at 200 yards. For some reason this barrel likes to be jammed, which wasn't my first choice since I'll be shooting PRS matches with this. Only jamming .005 doesn't pull the bullet out though, so no issue I suppose. I made a seating die from a Wilson blank using my chamber reamer. Resizing die was easy, swapped a 6.5 Creedmoor die with the correct .2820" bushing. Lilja 1:7 twist 3-groove barrel, went with the MK13 Mod7 contour.
