Try a cheap ol' soft point from like a 30'06.... you'll be surprised even more.

Its only 17gr of steel. And 55gr is faster.

1/4" of mild steel is not much of a challenge for most rifle calibers as you have discovered. Don't let this information get out or the bad guys will think all rifle ammunition is "armor pierceing"...

One of the reasons im doing this is to because a guy at work is wanting to market his own body armor using the ar500 armor plates. He directed me to the ar500 website to watch videos they have of their armor against various calibers. They shot the armor at a distance of only 15yrds with the xm855. That seemed to be too short of a distance. I was curious to see how well it held up at greater distances. He is wanting to give me a sample plate to test fire on. I was using the steel plate to try to determine what would be the most effective yardage for the xm855. I will definately have to do some more research on the xm855. I know these rounds are not armor piercing, just wanting to see how they stack up against armor. |

I have some of the ar500 round plates that I bought from widners and enjoyed pinging them at 150 yards with 223 55g soft point reloads and also with my 22-250 with my reloaded 50 g hornady zombie max bullets but on the third shot of the 22-250 it went clear thru with a 3/8 hole. amazed me but as they say speed kills and my reloads chronied at
avg. 4105 fps |

If you are testing it anyway, get some ballistic gelatin or fruit and find a way place it around all edges to show what the spalling could to do to someone.

the m193 has higher velocity so at close range it will have similar performance. At longer ranges 200-300+ yards the m855 will outperform the m193.

If you are testing it anyway, get some ballistic gelatin or fruit and find a way place it around all edges to show what the spalling could to do to someone. Man, there is truth to that. A couple months ago, I had a mock target range setup with 2 liter bottles filled with water, traditional rifle paper targets (with metal behind them), and some cans, etc. stuff to shoot. The first shot I took (at 200 yards mind you) hit near the bullseye of the paper target and the resulting fragments blew holes in my 2 liter bottles that I had planned to shoot at next. I pity anyone that would open fire on something like that at close range. Ive heard stories of people losing an eye (or worse) from the fragments. |

I've shot level III plate at 15 yards with M193 and M855. M855 left divets, where M193 almost broke through.

I've witnessed Federal XM193 punch holes in 3/8" AR 500. I'm still sitting on a case of it because I won't shoot it in 3-gun matches.

Was surprised a few years back when I shot a 1/4" steel plate with some regular Remington 55 gr. soft point ammo at 15 feet. Blew a clean hole through it.
That is a close distance I know. At 100 yards, probably would have just bounced off. Would have been interesting to see what kind of results I would have gotten with AR500 plate. |

I have shot a thick piece of mild steel, maybe 3/4 to 1" thick with both M193 and M855 out of a 11.5" barrel at maybe 50 yards. The 193 put a nice crater into it with no pen. The 855 actually penetrated with only the tip. The exit hole was only maybe .05", likley the diameter of the steel penetrator tip. It looked very cool. The M855 WILL penetrate mild steel more than M193 but only by a little.
The same piece of steel was also shot by an SKS (uk type of 7.62 ball ammo) and it made a slightly wider crater than the M193 but no pen. |

Yep. Speed= 4x the energy of mass. PO Ackley wrote about this when using the '06 and 270 Vs. 220 swift against tank plate. The '06 and 270 just splattered. The 220 swift impacts actually changed the metal structure and burnt through!

M1 carbine with ball rounds will punch through 1/4" plain steel plates at 100 yards, no problem.

It seems you would want the stoppage as close as possible, if it will stop at point blank, it should stop at 50 yards.... For some extensive testing, see TheTargetMan.com Thanks |
