thank you for the help. I have been using the calculator to try and narrow down which bullet or bullets I want to try. I have noticed that with my barrel twist rates bullets in the 140 and 150 are stable but have lower ballistic coefficients. I am not looking at taking an 800 yard shot at an elk but I am trying to take a lot of the guess work out of it. Would a 140 or 150 partition be ok for an elk or is it better to stick with the 160?
I also by luck stumbled on someones recipe for a load that shot berger 160 hunter classic rounds out of my rifle with great success. I just haven't looked in Bergers book to verify its a safe load.
Anywhere you're going to hunt elk in AZ, or the west, you'll be at an altitude that will stabilize any 160 gr bullet fully out of a 1:10. Nosler has load data listed online. Sure, 140 or 150 gr Partitions will kill elk, but 160's offer a bit more of a good thing if you get a steeply quartering shot. In a 7mm Rem, there's no point in going to a lighter bullet.
