Did some steel target, rifle testing yesterday and today.
I picked one 8" square target, hung it at an angle from a stand using a 1/2" bolt, and shot it with my .308 and .223 at 100 yards. I wanted to do kind of a torture test on it, so even though I should probably be shooting at 150 yards, I shot it at 100. After shooting, I ground off the face with a wire wheel grinder and re-painted it again so I could see the damage more clearly.
Here's some pics:
My 20" .308 was shooting 165gr A-Max's going about 2700 FPS IIRC, last time I chrono'd them.
My 16" AR was shooting factory ammo, I think it was Winchester 55gr .223, I also shot some Wolf 55gr steel cased stuff.
Did some testing yesterday and today.
I picked one 8" square target, hung it at an angle from a stand using a 1/2" bolt, and shot it with my .308 and .223 at 100 yards. I wanted to do a harder test on it even though I should probably be shooting at 150 yards. After shooting, I ground off the face with a wire wheel grinder and painted it again so I could see the damage more clearly.
My 20" .308 was shooting 165gr A-Max's going about 2700 FPS last time I chrono'd them.
My 16" AR was shooting factory ammo, I think it was Winchester 55gr .223, and also a half box of Wolf 55gr steel case.
The .308 made hardly any mark at all, I'm much more accurate with that one and I purposely shot some about a half inch away from the edge, and if I look for them, I can find one of them pretty easily. Not much of a mark, but a little bit of a dent. The other shots near the center, once painted, are pretty much impossible to find now that it's been shot more, but I can probably find that one edge shot if I look for it, I remember its kind of all alone in that area for some reason.
The .223 caused much more visible damage which I was surprised at. No dent to speak of in the steel, but definitely a small crater. The average sized crater is about 0.11 wide when measured with the calipers, no measurable depth to them though. If I feel around on the plate, sometimes I can find the marks, sometimes I can't. I've seen some steel targets that leave a little tiny dot of steel, not making a crater, but coming "out" of the steel when shot at 100yds with .223. Those looked more like a tiny bit weld spatter, not mine though... Mine definitely leaves a small crater.
You'll see one shot on the bottom edge that took a bite out of it. It was with the Winchester 55gr using the 16". I've heard that edge shots on AR500 steel will usually take a small chunk out of it... Anybody else had this happen?
I also set the steel up so it was straight vertical with no angle, then repainted it, and shot it again with the AR. At the time, It looked like the craters were deeper and more pronounced, so I only took 5 shots with that. Now that I've wire wheeled and repainted the steel though, I can't tell which impacts those were.
You'll also see 5 rather large and deep craters on there too. Those were shot with my 24" AR using 55gr SP reloads, going over 3000 FPS. I won't be shooting them at 100 yards anymore that's for sure. Again... I wanted to do a torture test. I shot one close to edge, and 4 near the middle, before I stopped. No difference between them as far as damage to the steel. No dents, but the deepest hole was .021 deep. It definitely removed some of the AR500 steel. I will not be using this side of this target for anything but longer range rifle shots from now on.
With the .308, I shot 10 shots shots on the steel, hits on all of them. The 24" AR was shot 5 times, all hits. Those rifles were scoped.
The 16" AR had only an Aimpoint on it with zero magnification. I shot 50 shots total with that, and missed about 5 I think. Using white paint at 100 yards with my eyes, I couldn't tell exactly where the target was. If it wasn't for the ping, I'd have no idea if they were hits or not. I could easily hear the hits through my ear protection at 100 yards, which was nice.
I also cleaned off the torso target and repainted it. No visible damage after about 50 shots of 9mm 115gr reloads going around 1150 FPS, which I wouldn't think there would be.
I'm glad I made a couple larger gongs for long range rifle, but I'm pretty sure I'll be using this steel mostly for pistol and shotgun work. I'll probably make some more square targets with the leftover piece I have. I also need to make some more stands for them, but I think I've got that design figured out.
I haven't shot much at these targets so far, but I'm very happy with them and can't wait to get more range time on them. I've been doing some other work on the range too. Had a skid loader down there, leveled it out, moved a bunch of logs, made a more defined berm, am checking into designs on building a lumber awning, etc... A few more trees need to go though.
