Target steel type?

[wintermute76]

I'm looking to make some half size IPSC steel plate targets. I have found a typical hardness for high velocity use as 500 Brinell (about 51-52 Rockwell C) But steel type is uncertain. I have found MIL-A-46100 is a high hard armor plate steel for multiple hit use. It's similar to 86xx steels, but not quite.

Anyone have any other insights into what kind of steel is useable?

The free kind is the best.

Aside from 500 Brinell is AR500. I have no idea what that means, but some target makers refer to AR500 and usually when that is the case, they aren't using the Brinell scale.

Well free is always good I"d just like to have something that will stand up to abuse from the FAL and I won't have to rebuild every couple of months.

I was looking at www.letargets.com and they mention 500 brinell a few times. My instructor also said the better targets are 500 Brinell.

AR500 is "abrasive resistant" steel , I use a lot of it . Typically found in high wear industrial type parts , loader and backhoe buckets and cutting edges , snowplow cutting edges, street sweeper wear parts. Check out your local highway dept., especially in the snowbelt , 'tis the time of year to change those cutting edges, the used ones are usually scrapped. Ray

Haha! well - I was sorta funnin ya Ray but - to be serious tho.... Sure - I'd love a slice of blade if at all possible.

Can collect of course! (Which'd mean turning up with a few small artillery pieces for excercize at a certain range! Heck - clocks go back soon ... this is gonna make the days awful short.

Have to fix something before too long methinks.

most of the mettalic silhouette targets were made of T-1 steel and at 50 meters they took a lot harder hit than anything that you would shoot at a IPSC match

Anybody have any experience with using a abrasive cutting wheel or cutting blade on AR500 steel?

On my range I use AR500 from both Arntzen targets:

and Quality Targets:

I’ve been shooting both with everything from .22s to .300WM with no ill effect for about 5 years now.
