RE: 300gr. Shockwave????
When shockwaves first came out in my area they were 300 grain. And they were used on deer, moose, elk, you name it they got shot with it. Then the 250 started to get used and with great results. I always like a heavy bullet (personal preference I guess) and I am sure it would work fine for what you want. But which ever is most accurate would be my choice.
