you can get lapua brass for the 243, my savage with 9.25 twist shoots the 95 smks very well out to 1000. I t shoots well enough that I would not bother with the fireforming just for a few more fps. check out 6mmbr . com they have some good comparisions between the two
How do you find the 243AI does on the coyotes as far as pelt damage is concerned?

The 243 and 240 gibbs twisted for the 105's have a tight neck chamber and shoot really good to a 1000 yards. They are all very accurate. Of the ones I have the 243 AI is slightly more accurate than the others. I zero them at 300 yards and the 243 AI will consistently shoot 5/8" groups at that range. They are great varminters and coyote rifles which is why I built them. The brass for the 240 wby is just to high and can't be made from anything else so it gets the least use although it is a great performer. I did it for my wife and son to shoot deer and antelope with because it has virtually no recoil. None of these have recoil to mention. For a coyote rifle I think you would be very pleased with any of these.
