Re: 7mm on elk
I was disapointed to find no loading data in the new Barnes #3 manual for the 7MM RUM, although it does have the 300, 338, 375 RUM data.
I would be tempted to use a premium bullet to between 500 and 800yds depending on muzzle vel. after that terminal velocity decreases and so would the expansion diameter, so a 1500yd shot would need less energy to penitrate because dia. is closer to 7MM than to a probable 12MM 300yd shot.
Just my theory.
Len, that's a very impressive setup you've got there, SMOKIN! I'm trying not to be envious once again. You are becoming my hero!
