Just tooling up for 180 grain Semi-FP GC. .310 size die. Sould be limited more by the leads velocity restrictions than the weight, so that's one reason for the 180, plus a bit more gas pressure or volume. And there is always paper patching if straight up hard cast doesn't work. I will keep you posted, it is coming. But I just joined up here, and was glad to see the comments on this topic.

Well.. I tried the 168 grain ballistic tips and they seem to fly good.

I just did a function test of some 168 gr. Nosler Ballistic tips, and had jamming. I noted the 2.8" OAL and ignored it completely.. But that seems to be the problem. This batch was 2.860. But the neat thing is during the function test, with 10 rounds fired, the fouling shot was wild about an inch, the following 9 cut a ragged hole the 3/4" center to center at 50 yards. I should have paid more attention to see if it was a magazine jam, or a chambering jam, but believe it to have been the latter. It looked like a jam. So I am going to play with seating depth... but as a bolt and break action guy, I want to seat to engraving, or just short of it. Old habit. I don't want to seat away from the lands any more than I have to. I am thinking though that a bit of polishing in the frame there might allow a bit more room, and slick up the feeding. Has anybody here played around with that?
