My final load for the .270 is IMR7828-69.5gr, 140 Accubond. This rifle is a real pleasure to shoot and I am very happy with it. Kirby did an awesome job and I have to give credit to Mike Rock. He did a great job with the deep cut fluting. The barrel is 1.120 at the threads straight for 6 inches and then a straight taper that ends at .75" dia at the muzzle. .257Wby Rebarreled by Chris Mathews is next.

I was just starting to narrow down my load development when the .257 started giving my trouble. Just last week while at the range, the firing pin released when I closed the bolt. I did not pull the trigger. The primer was not hit, but the cocking piece slipped off the sear and wedged on top of it. I could not even open the bolt until the trigger was pulled, releasing the sear and unwedging the cocking piece. I tried to close the bolt (with the chamber empty) several times and and the firing pin released about 50% of the time. I want to point out that Chris did not work on the trigger and this is something that developed about 4 months after getting the rifle back. I suspect that the tolerance stack up in all the parts are at minimum material condition and whatever wear has occured with normal wear of cycling the bolt has allowed the cocking piece to slip off the sear. I just mailed the rifle to a Wby service center for repair. I'll see what they say in about 3 weeks. Well that's the end of my report. Take care, Vic [/QUOTE]
