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?

I strongly recommend the Speer 70 Grain TNT for the 6MM varminters. This bullet has won out over all the lighter bullets and is economical to shoot.

I don't know what the rate of twist is on your Remington, but my old 7400 didn't like the lighter weght bullets. I got best results from 95-grainers. Keep in mind, I was attempting to make a good deer rifle into a varmint gun. It just wasn't up to the task. I've since traded the 7400 for a Winchester 70 in 270 wsm. I can't wait to find out what kind of varmint loads I can get out of the short mag.

I'm pretty sure the twist is 1-10", from what I've ready that should work fine on 55gr. I think I'm going to try the 55gr and just see what I get out of them. Worst case is I switch to a different bullet after three trip to the prairie dog town, because that will be all it takes to use the 250 bullets I ordered.

By the way here is a good article on the twist rates with the win .243 and the old Rem 6mm and why the .243 won out. http://www.outdoorlife.com/outdoor/s...540468,00.html

Great article. I especially loved the quote at the end. Thanks
