Guy selling AR500 plate?

Laser is good but it still burns through and creates heat....water jet is way better yet, it is cut with high pressure water and the plate will be cool to the touch as soon as it is done

water jet is how they cut the small holes in bank teller glass and many other things, it is great for when you don`t want to alter somethings heat treating
 
I ended up buying from Alberta Tactical.

I was also in there yesterday and saw a few still hanging on the wall.

Looked like (2) 3", (1) 4-5", and (1) 12"?

The other guy couldn't give concrete answers so I lost interest.
 
I would think there'd be lots of shops around alberta with it on hand from repairing heavy equipment.
 
You would think... I have tried hitting up a couple of shops, but there is very little waste. And when they want to sell the off cuts, it is for some obscene amount because of inflated prices industry is willing to pay out here.
 
Guys,

We could cut these plates with water-jet if we wanted to, but it's unnecessary and slow, so it would drive costs up. With laser cutting them the way we are, there is a VERY small heat affected zone, which may or may not get hot enough to alter the temper on the steel. A good guess is that half the zone is affected.

Here's a pic of one of the targets. The red coating is the primer that the steel is sprayed with before being cut. You can see the black line just on the very edge of the target where the primer was burned off. That is the heat affected zone.

If youre shooting beyond 500+ meters I think buying AR500 is a waste of your money. Ive got plates (mild steel) set out where I shoot that have sustained hundreds of hits with little distortion. Our 920m target is an IDPA size torso that is cut from 1/2" plate and is still holding up fine after 2 seasons of shooting everything from 6.5-338 cal.
 
We've done some major damage to mild steel from 1000 yards and in with rifles from .223 to .338LMAI, and that includes some hardened railway steel, as well as other types of mild steel. We've used certain types of mild steel that can sustain hits at 1000+ yards without showing much damage, but I'm unaware of exactly what type of steel it is. At 1762 yards the 3/8" thick mild stuff holds up fine. Typically, mild steel does the job for a while, but eventually you need to replace it to avoid dangerous ricochets. The reasons I like AR500 are more for the unique audible impact report, and the fact that you can make AR500 targets from thinner steel, so because they're lighter weight, they swing more when hit compared to thicker and heavier mild steel targets.
 
You have some valid points. I guess I see it from a different perspective because I can get whatever I want for free.

I have a bunch of 3/4" 12x12 plates that were base-plates cut off of columns. So far they have held up well with only .338 Lapua making any discernable marks. When they get shot out I'll just get some more.

Forgot to mention that another reason I like AR500 more than mild, is because since the steel is so hard, the bullets splatter into nice round little marks on the painted surface, which is easy to see through the spotting scope from as far as 1 mile away. Mild steel often is full of pock marks, making the new hits difficult to distinguish. With AR500 you can measure the group and write down the particulars directly on the plate with a sharpy, take a picture for your range notes and records, and then re-paint the plate and start over. Another result of the steel being so hard and unforgiving on the bullet, is that the bullets fragment when they impact, so there aren't typically any real ricochets to speak of.
 
If your worried about a HAZ on the edge of your AR500 target your an idiot or have lost touch with reality. It's a target! Shoot the dam thing and stop pretending your an engineer.

I feel better now.

Sorry for the rant!

I ran a very large cnc plasma/torch table for years and have made tens of thousands of parts, I know the difference.....
