A few have already hailed the 6MM Creedmore. I'll add to the list. I have 6MM Rem Mag and I love it. I picked up the 6MM CM from Seekins (Havak Pro) a couple of seasons back. (It's the one shown in my profile pic btw.) I'm not a varmint hunter per se, but once in a while I take out a coyote. I've used this gun on targets, deer, and antelope. There are a few ways to get what you're after. This is one of them for sure.
An additional note . . . last summer I put this 6MM CM to the test on metal with light to moderate wind conditions. I was super impressed. First round hits from 300-1000 yards (100 yard increments) with the exception of 700 yards. Shooter error . . . which accounts for nearly all of my misses! My spotter pushed me to try 1350 yards. So, I had a second round hit at 1350. Then we went a mile. The wind had picked up a little. I missed 4 in a row and then got my dope right. Then I hit 4 in a row and went home pleased. I'm a reloader and I believe in reloading for increased accuracy. However, I've only shot one bullet through this 6MM CM so far. Hornady Match 108 gr. People can say whatever they want about factory ammo, but this gun loves this factory bullet so much that I haven't made a single round for it yet. I probably will but not for the sake of accuracy.
I shot three whitetail does and an antelope buck with this 6MM CM last year. It performed very well. Closest shots were 40 yards, farthest were 210 yards (on the antelope). It performed well. At 40 yards I had some meat splatter on the entry shoulder. I'd recommend lung shots up close or you'll lose some meat. At 210 yards it performed perfectly. I'm sure it will perform at greater distances on animals, but I haven't tried it yet.
Good luck and have fun with this project!
