Hi Guys.
I am new (back) to this board after a few years. I've gotten away from bench shooting and am getting back into it. Sort of. I had a 6PPC built on a Rem. XR100 action hart bbl. w/262 neck pillar bedded into the original stock, Jewel trigger, and Leu. 45x45 scope. I had some decent groups fire forming brass and figured things would be good when developing loads. Most things I have read point to N133 as the powder of choice for the PPC. With most of the claims in the 28.6gn to 29.2 and over on some behind a 68gn bullet of some kind or other. (I've tried Berger 68, Bart's Headhunter, and Bart's Ultra). At about 28.8 I am getting brass flowing into the ejector hole. Bolt lift is just a bit of resistence but it does not click at the top. Velecities at those charges in this rifle are 3400 and above. Extreme spreads of 9 or less and ovbiously SD's are 4 or there about. Primers are flat and cratered and I'm thinking this is WAY too much pressure. Accuracy seems to be erratic with fliers that I don't think I caused. The dot of that 45 horse Leupold seems to be where it should be when rifle cracks. Is my brass that has those ejector marks ruined for max accuracy or will it be ok yet. I'm a bit frustrated and somewhat dissapointed. This one is not as easy to get to shoot as my .222x35 was back in the late '80s. Help!!!
Thanks, Lonnie
