This is perhaps a goofy question, but I'm compelled to ask it for some reason. I realize that none of this is ideal regarding the selection of specific ammunition, or even the caliber at this range, but that's what I want to limit this to.

If one had to make a shot in the 300-600 yard range out of a 16" or 20" AR, which one would be the better round from a stand point of Terminal Ballistics?

5.56mm M-193

5.56mm M-855
.223 55gr Soft Point

.223 45gr WWB Hollow point.

For giggles I'll throw in .223 52gr OTM and Remington's 50gr hollow point too.

Well, past the 300 yard mark, I would move to something bigger, i.e., 308.

If I couldn't, well, out of those you listed, I'd go with M855 for +300 yards.

Just a reminder: There are a lot better performing loads at those distances than you listed

i've made a couple of shots at the distances youre talking about with M855. shot placement is key. but a scoped AR and someone who knows how to use it can do it. i remember thinking at the time that some 69gr ballistic tips or even some of the 55gr moly coated ballistic tips i had at home would have been the schizznit but alas i was limited to M855.

I remember plugging targets at 300M with M-193 and M-855 when I was in the Army - and this was before ACOG's and the like. Definatly doable.

But what's the terminal performance? I was thinking the 55gr Soft Point would be better due to the fact that it would still mushroom where the FMJ type rounds would be well past their frag threshold.

Shameless self-serving Bump.

i think the first thing you need to worry about before thinking of terminal ballistics, is if the bullet can accurately hit your target. you want the heaviest bullet you have, when you shoot at 600.

i shoot service rifle matches and used to shoot 69g. sierras, federal gold medal and if there was wind, it could play hell with accuracy. it could blow you left/right of the target. i shoot 77g sierras now and it's better.

i think i shot some surplus malay at a match at the 200/300 yd lines and it wasn't too bad. i didn't shoot it at 600 though.

Thanks for the response. My rifle likes the 68gr OTM from Black Hills at longer range, and as it's a 1:9 twist I figure it's a pretty good match.

But I'm still curious about the terminals at those longer ranges. What's better? A non- fragmenting FMJ or an expanding soft point? I know their not ideal for the range.
