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.
Edit :
For those interested, I've ended up changing my load quite a bit. My last PRS match last month I was really struggling with pressure issue's. It went so far that I was even putting my loaded magazines in coolers before I'd shoot to limit my stiff bolt lift
(definitely ruined some brass, which sucks.) Granted, it was 95 degrees out.
After visiting with a good friend, I decided to completely rework my load over. In my initial load development I spent a lot of time trying to get it to shoot at around .020" jump. I was encouraged to try jumping it between .060" and .100" and really drop my load back.
The attached photo's are some new loads I've settled on. 37.5 grains of powder, seated 2.800" which is .060" jump. Velocity was right at 2800, which is honestly a little slower than I was hoping for, but as good as it shoots I'm not going to complain. I've never been one to care about velocity, I am more concerned with how it performs on paper and steel at distance. Running it over the chrono, and 37.5 grains of H4350 gave me 2795 average over a 5 shot group, and a very nice ES of 6. I'll shoot it again in the morning at distance to verify my velocity and drops, and then hopefully smack a couple speed goats with it over the next couple of weeks.
