A couple of times in the last six months I have tried to contact wvcruffler, asking about any progress he made with his bolt rifle project. No replies have come in yet. When last heard from, he was stuck with the problem of trying to get his 1" dia Green Mtn bbl installed on an action that required 1" diameter barrel threads.

vz58-
I assume you're talking about the AK you described last May in the thread
Question about 450b pressures?
Based on my experience, I don't think you're going to have any problems with bullets coming apart from a too-quick twist. To get a bullet going fast enough to possibly come apart, light bullets will be needed. The lightest commonly available 451/452 bullets are the 160-grain Barnes and General bullets. These are solid copper and are not likely to come apart at most any achievable speed.
The next lightest would be the 185-grain bullets from numerous makers. I picked the Prvi Partizan jacketed soft points, which were about the cheapest available, and I supposed to be of the weakest construction. The description of my efforts to blow it up by spinning it with high velocity in a 1:16 twist barrel are in this thread:
Trying to Blow Up a Bullet That shooting was with a 20-inch barrel. Really pouring on the coal in another bolt rifle with a 1:24" twist 26" barrel, I've gotten 3000 fps from these without any detectable blowups.
If you have any suggestions about which bullet is most likely to come apart when driven at high rotational velocity, please post them. I'd like to try Wildcatter's trick of getting one to blow up.
