.243 win, AMAX versus Matchking...

I'm pretty new here, so please forgive me if this question has already been answered 1000 times... [img]/ubbthreads/images/graemlins/blush.gif[/img] [img]/ubbthreads/images/graemlins/laugh.gif[/img]

I checked the search function, and found nothing...

Anyway, I'm shooting a .243 win with an 8 twist Douglas barrel. It's a very accurate Remington 788 action. By using 48.5 grains of Hodgdon Retumbo and Hornady's 105 grain AMAX, I'm getting some pretty respectable groups at 1000 yards, and have connected with one groundhog at 755 yards.

I say "connected," because even though he went airborne when I hit him, and did a somersault before landing--he got back into his hole. I thought this could have been a fluke, but I then hit a smaller groundhog at 540 yards TWICE and he was still kicking when I got to him.

Then, at about 170 yards this deer season, I KNOW I hit that small doe right near the kill zone, but it was able to easily run away.

Is there something wrong with the 105 grain 6mm Hornady AMAX? I mean, you'd think it would at least make quick work of a groundhog, no? To that bullet's credit, the groundhog which I hit twice at 540 yards was pretty messed up--he was just clinging to life better than I would have ever thought...

I've picked up my first box of 107 SMKs this evening, and figure 48 to 48.3 grains of Retumbo should get me at least 2900 fps from the 24" barrel.

Just wondering what you guys think...

Dan

Wish I could talk for the 105 grain amax out of your 243 but I personally use the 87gr. vmax over reloader 19. It Shoots great out of my gun and has made 3 1shot kills on whitetails. But for your amax out of your 243 I dont know what to say. The only amax kill I have ever seen was a 162gr. out of a 7mm stw on a coyote. It hit him in the chest and gave the dog a much bigger but hole than his parents did [img]/ubbthreads/images/graemlins/smile.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]

Re: .243 win, AMAX versus Matchking...

The Amax is a very explosive bullet. I can't imagine that you would hit a deer in the vitals and have it run off. If anything, maybe you hit it in the shoulder and the bullet never entered the vitals. I wouldn't expect the 107 SMK to get very much expansion at all on chucks or groundhogs. especeially @ long ranges where the velocity is lacking.

The 105 Amax is a better choice, in my opinion, for varmints than the 107 SMK. I've killed quite a few prarie dogs w/this bullet from my .243 between 500 and 1100 yds. Each time the bullet expansion was quite dramatic. Even over 1000 yds.

Re: .243 win, AMAX versus Matchking...

Well... this is the kind of feedback I was looking for. Real world stuff that differs from my own experience. It could be that I've just had a string of bad luck with the 105 AMAX. And it is possible that the bullet struck that small deer in a less than opportune place, but the shot broke good, and zero checked good later that day. So I don't know.

And get this: I forgot to mention the last groundhog I shot with the 105 AMAX at 438 yards. I hit him in through the mid section (according to the guy who was on the spotting scope) and he flopped around about five seconds and dragged himself back into his hole. The only groundhog that's been DRT (dead right there) on the shot was at a little over 200 yards.

I would think that the 105 AMAX should be able to take full advantage of that ballistic tip and, yes, expand violently. So I'm at a loss here. I might entertain the thought that I actually missed that deer (I was bracing off the side of a small locust tree) but as close as he was, with my zero at 100 yards, the shot should have been no lower than an inch or so. And with three bad results on groundhogs, I can't help but think something's up.

I don't know if the 1:8 barrel twist could have any significant effect on the bullet's terminal performance--but I have read military sniper publications that indicate that the slowest twist practical gives a better chance of bullet upset (and commensurate tumble) on live targets--FWIW...

I have a 6mm Rem and I use 87gr V-maxs which cause dramatic explosions on small game. The only A-max I have shot a deer with was out of my 300 win mag at 460 yards and he only took 3 steps.

Maybe with FMJ's, but with a bullet like the AMAX the faster the twist the faster the bullet comes apart. I really dont know what to say as Amax's are built like Ballistic Tips.
