NOT happy with the 300grMK

went hunting this weekend with tikkamike here on the site. i was packing my 338 with 300gr matchkings at 3120fps. had an atelope doe at 925 yds, hit her right behind the shoulder and she just stood there like nothing happened. hit her again and nothing. all my spotters couldnt tell if i was hitting or not and wit ammo being expensive i grabbed my friends 7rum and again with the same results. i was a little upset making the drive to the antelope as i thought i was missing. but when we got to the antelpoe she was laying down with her head up so i put a finishing shot in the head at 300yds with my friends 6xc. when we walked up the the antelope come to find out i had hit every shot. all shots were liver and forward except one. the 338 300gr mk just poked right through like a fmj would have. with no damage at all. this was the toughest goat i have ever seen taking multiple vital shots and still alive???? kinda has me stumped.

Did any of the bullets impact bone?

FWIW, I figure that liver only hits without a lot of trauma result in about an hour for most game animals to expire.

Re: NOT happy with the 300grMK

I wouldn't really expect a 300 SMK to do a whole lot on an antelope without putting it on the front shoulder. An antelope ain't much to get a bullet that big to do much. Most of the video I have found of a 300 SMK on goats they all run unless it is put on bone, then the results are a rather dramatic smack down!

Re: NOT happy with the 300grMK

Sierra does not recommend using these on smaller game and this is why. Lots of these bullets are slightly different then others I have seen problems like this happen with almost all bullets. I have had good luck with them on deer and other game with no problem.It is kinda strange but not unheard of for this to happen. You want something that will open more up go to the barns or nosler bullets like the accubond or the balistic tip. Like i said i have had no problems like this but i shoot them 250 FPS faster. The problem sounds like you just didnt hit enough bone to make the bullet fragment enough. I could see this happening with these prairie goats very easily.

+1 on hitting bone with that bullet, its a huge heavy bullet going through a really thin skinned animal at long range, I think you would have to hit bone with most bullets to get descent expansion. Besides that sounds like you made some great shots at long range. Good shooting!
