Re: Alliant Power Pro 2000-MR
I have pierced primers with Alliant 2000MR, but it was hot... so hot that it hurt to touch my ammo. I think I worked the load up in 80 degree temps and shot it in 115 degree temps with no shade.
Still, I had no chrony to document the temperature dependence of velocity. But honestly, I was blowing primers on FGMM that day.
