Well, there was no publised data to start with so I started real low. Here's what I got:
Case: Lapua
Primer: CCI BR-2
Bullet: Berger 185 BT LR
Powder: Hodgdon Superformance
Ladder Test:
Charge Weight Velocity
43.0 grns 2200 fps
43.5 grns 2213 fps
44.0 grns 2215 fps
44.5 grns 2241 fps
45.0 grns 2257 fps
45.5 grns 2300 fps
46.0 grns 2334 fps
46.5 grns 2382 fps
47.0 grns 2397 fps
47.5 grns 2443 fps
48.0 grns 2453 fps
48.5 grns 2505 fps
Pressure was mininal in all tested loads (really dirty case necks). Hodgdon had no posted data for the .308, so I was pretty much flying blind. I'm not sure if this powder has any potential in the .308 or not, I'm gonna load up a few more rounds for one more outing and see if I can get any worth while velocities before hitting pressure, otherwise I'm just gonna scrap the project and agree with Hodgdon for not posting any data for the .308 win.
