I just recently got back into Prairie Dog hunting after a 6 year break. I used to shoot a bunch of 75 gr hollow points, but have seen that there is a lot of newer smaller bullets out on the market now. I'm currently thinking about using Nosler 55gr Ballistic Tips. From what I've seen on the net I can get close to 4000 fps out of this bullet. Probably less with my rifle since it only has an 18.5" barrel.
I shoot a Remington Mohawk 600 (.243).

Suggestions? Opinions?
