[QUOTE="cape cove, post: 2584808, member: 95503"] Bullets used were the 130 gr Hornady Interlock Spt and the 150 gr Hornady Interlock, cases were Weatherby. With my slow lot of H-450 with the 130 gr I used 78 grs of H- 450 with a Rem 91/2 M., with an oal of 3.300. Velocity was 3327 ft/sec with sub MOA accuracy. With the faster lot I had I used 73 grs of H-450 with the same components. With the 150 gr Hornady I only tested with the slow lot . I used 73.5 gr H-450 with a Fed 215 and an oal of 3.295. Velocity was close to 3200 ft/sec and accuracy was .8 MOA. These velocity #'s are from my 24" barrel. These are max safe loads in my rifle with the powder lot's used. Back off 10% and work up. We are talking about a 270 Weatherby magnum. [/QUOTE]
