Data from COW #8:

45 gr SP 30.0 IMR-4320 = 3600 fps
50 gr SP 31.0 H380 = 3500
55 gr SP 27.0 IMR 4320 = 3300
60 gr SP 28.0 IMR-4064 = 3300

There are other loads with other powders listed, but these gave the best velocity. If you use BL-C2 or IMR-3031 let me know, there is some data shown for those also. And have fun with the blaster! It's apparently one of those rounds that can benefit most from a little extra care in handloading, brass prep, etc. Keep us posted!

60 Gr SP 28.0 IMR-4064 = 3300, or
60 Gr SP 31.0 H380 = 3300 (COW-8)

From The Hornady 4th Edition:

60 gr SP 28.3 IMR-4064 = 3300
60 gr SP 29.4 IMR-4320 = 3300
60 gr SP 31.1 H380 = 3300
They also show data for H4198, IMR-3031, BL-C2, and H4895, but velocities shown are lower. BTW, these are ALL MAXIMUM LOADs. Work up carefully, as always.

Sounds like fun! The old base-of-the-ear trick? Or is that bullet tough enough for a shoulder shot? I know for years Nosler made a solid base 60 grainer, but I've never tried any. Is this the same thing? I'd heard at one point that they'd dropped it. :roll: Maybe they got smart and brought it back.

A buddy of mine out west uses a 22-250 with a similar bullet for all his deer hunting. Says it drops them so fast they look like they were pole-axed. But he's only killed about 130, what does he know?
