I recently purchased a Browning A-bolt in 243 WSSM for my grandson to hunt deer and antelope with. After some trial and error at the reloading bench we finally came up with a tack driver load with a Barnes TTSX 80 Grain bullet. The bullet is currently shooting at 3550 FPS and it shoots about a 5/8" group at 100 yards. We took it on our antelope hunting trip this year in eastern Montana and I cannot say enough about this little cartridge. It shoots flat and it hits like a mack truck. Now antelope might not be the most hardy animal in the world but this little cartridge flat took em down. Two shots, two antelope dead in their tracks. One at a 150 yards the other at 367 yards. I would like to hear any feedback that anyone may have on their experiences with this cartridge. it sure looks to be a favorite in our hunting camp when the smaller game is what we are after. On a side note it sure puts a hurtin on coyotes as well!!!
