Here's the fifth draft of a chamber reamer that I'm planning on having made.
I'm sorry if the image doesn't come through too clearly. Actually I see that it didn't come through at all in the body of the message. Obviously, I need help with that process as well. The link should still work.
I tried to set this up so that the body/boatail junction of the 200g Accubond would be about .020 below the neck/shoulder junction with a 2.850 case length and a .270 neck length. This should give me a few thousandths worth of rifling to play with before the bullet is set out to far. That's the plan anyway.
Dave at PTG thinks this will work fine but he doesn't care for the short neck. Neither to I, but I'll risk it to maximize volume. I remember STL and S1 awhile back with their 30 Wolf (about the same volume--338 Lap case made into a 30-338 Lap Imp. with a short neck to max volume)project that had a much shorter neck than this and S1 was saying that he was having pretty good barrel life. The idea is to maximize available volume from the 300RUM case.
I'm for additional comments/suggestions...I'm putting on body armor as I write this.
