[QUOTE="Grifm, post: 2808882, member: 116508"] I’ve never shot the BD2 but I’d say be careful. If you look at the AH the only part of the bullet that full diameter is the scallops on the side, I think they call them PDBs so the bearing surface is very small. I haven’t really done much research into the BD2 but I did read that they’re designed to reduce bearing surface. Looking at the pictures I can’t immgine that they’ve reduced the bearing surface as much as the AH. Because of that I would expect to hit pressure a bit earlier. For reference in the same rifle I could push the 150 TTSX to just over 2900 with CFE223. LVR is a bit slower than CFE so maybe you could get a little more velocity with LVR but I’d expect the BD2 to fall somewhere between those two but if I had to guess I’d say somewhere around 3050 would be a reasonable velocity for initial calculations. -Matt [/QUOTE]
