[QUOTE="tim_w, post: 2645886, member: 11132"] I do not have hands on experience with the 338XC. How was bolt lift and head expansion on the 26gr-27gr? Did you shoot for elevation check or just powder psi limit? Personally, as H50 is a extreme line powder, on vel alone, I would investigate 26-26.5 gr. Just give that barrel time to cool between shots. Personally, I only do load dev on cases that have had a med psi fireform load first. To find pressure limits etc I shoot one single case for all the loads reloading at the range. I know thats not possible for some people. Did you have any other pressure signs @128 gr? Wondering if it's firing pin gap related? [/QUOTE]
