does anyone use this ammo if so what do u think about it thinking of using it in 243

It's a varmint bullet I wouldn't use it on any large game. That being said they are devastating to coyotes with the velocity they are running.

i just bought a savage model 12 predater i think thats what im going to use

It should be a laser beam then if the rifle like's the round.

i guess ill find out thanks

Have a friend that uses that load for just about everything in his Savage 243. He is deadly with it, but on pigs and deer uses almost exclusively head shots.
