Hey guys, I just recently built a .338 Lapua and am looking to put together some targets for long range shooting. Using 3/8 mild steel plate my .243 puts a large dent in it at 1000 yards but does not pass through. I dont want to ruin my current steel plates shooting them with the .338. I have lots of AR500 steel targets but the biggest one is basically 75% of the size of a standard ipsc target. My question is, what material are you using and what size are the targets you shoot at for 1500 to 1900 yard shooting? I have a source locally for 3/8 AR500 plate and can get it cut to any size necessary.
