I thought someone wanted this information so I collected it.
Then I discovered they didn't want it after all. But I am posting it anyway.
I hope someone can use it.

I did like it! Thank you!

Gonna build a 6.5-300 PRC IMP (Rich Sherman's 26 Sherman).
Gonnna shoot lighter Hammers, very fast!

That rifle was a guaranteed 1 1/2 MOA rifle. So I disassembled it and sold all the parts.

I redid the concept with the Proof carbon and 7mm. I regular load is Hammer Hunter Tipped 132 grain at 3,665 feet per second. I tried the Hunter Hammer 90 grain. Their velocity was 4,290 feet per second.
