Chap,
I am going mid May sso it shouldn't be too hot. So I should figure on firing 20 shots and 1/2 hour cool down...sound right to you?

I'm figuring for my 3 day shoot of the following:

204 Ruger 600 rounds
Ar-15 600 rounds
7mm Rem 160 rounds
17HMR 500 rounds

Outfitter is telling me that the 17 will be near useless with wind there.

How does this bullet count sound to you?
