26" proof sendero 7.5tw carbon, cut to terminus Apollo tenon, 5/8x24 muzzle. Round count is 150. Chamber cut by J. Linenbach at Kinport Peak Rifles
Brass: 99pcs from old barrel(proof replaced, had psi issues) 2x firings clear boxes, 100pcs(2 toned boxes) nk turned to clean up and give 4k neck clearance, 50x once fired, 50x twice fired.
Some the brass has ejector marks, however these loads were not run hot. The terminus action it was on, had way too much ejector spring psi, it did this same thing when I put a 6.5 saum on. I polished the bolt face and ejector hole, polished the ejector and reduced spring psi and things looked good. The highest charge this barrel saw was 59gr H1000 witj 131 blackjacks at 3110 while breaking it in. The majority of first firings were at 57.5gr. After breakin i ran 57.8gr H1000 at 3100 as the rifle liked this speed.

Dies: buyer will get to choose either the Hornady bushing fl set, or forster fl non bushing set, and I'll sell the other.

1300$
