.243s seem to be popular around here. The versatile caliber can be used for ground squirrels or deer.
But I have found them to be a little sensitive to the rate of twist. If you buy a varmiter .243 it may not be suited for the heavier .243 projectiles. I have an old Remington 725 that has a 9" in 1. (I think 10" in 1 revolution is pretty standard). It likes the heavier bullets. Won't group anything smaller than 95 gr bullets. My best loads is are 95gr to 100gr pointeds with IMR 4831.
Another .243, Remington pump, I have has a 10" in 1 twist and it's a little more versatile.
Anyway check your rate of twist if your .243 doesn't like some bullet weights or designs.
