I just thought I'd mention this. Several of my buddies and I took out our M-1 Garands and shot them yesterday. Yes, it rained hard the whole time, but luckily we were able to shoot from under a cover. Back to the point. I had bought some of this factory loaded Gibbs .30-06 at the Seymour gun show quite a while back. It is supposedly loaded with 150 gr. FMJ bullets. The first thing I noticed when comparing it to military M-2 ball was that the cartridge overall length of the Gibbs was much shorter. When I fired this ammo, some primer pockets blew out and the others were flat and cratered. If you see any of this ammo floating around, steer clear of it. I'll either give mine away to a buddy to pull and use for components or I'll do it myself, but I won't be shooting any more of it. I suspect that the excessive pressures were caused by the bullet being seated way too deeply in the case. I doubt that there is much of this ammo floating around, but I thought I'd give a report, just in case. BTW, I did have some rounds of factory M-2 clone ammo, and it performed great!
