Can't say about coyotes, but my 53gr TSX over Varget in a heavy barrel Kimber .223 has taken 8 Texas Whitetail deer and 2 pigs in as many shots over 5 seasons, all dropped in their tracks. 10 for 10 and 30 left in the box. Best performer for my .223 I have found. Never found one in the animal, all through and through penetration.
Anyone use the 45gr TSX or 50gr TTSX? If all weights of the TSX type bullets penetrate completely, what is the advantage of using a heavier version of it like 55gr? Wouldn't faster and flatter be adventageous to hunters at reasonable predator hunting distances say under 300 yards?
If i may interject, I haven't shot TSX's as yet on game, but I have been researching the lite wt. .224's actually for deer cuz dad has a Savage 24 in 223/12 that he would like to try on them. I think it's a 12 twist (have to confirm that) and was nervous about the length of the mono-metal bullets vs twist in his gun. I have read that most folks are getting pass-throughs on deer, broadside, ribs, with even the 45 TSX's! Anybody be able to confirm that on deer or even hogs? I am looking to eventually have us on all mono-metals for big game.
