Thread: Steel Target Thickness

You’ll go through it or make very big dents at 200m with most calibers. Usually 10mm but 450 will crater at 100m
What you have will be perfect for rimfire targets.
If they are big plates you should be fine with non mags at about 800m onwards. .223 should be ok from 300m maybe.
I’m talking as far as making no surface damage as that can cause ricochet.
I’ve seen 300wsm blow clean through 450 10mm at 100m
I’ve seen 338 lapua blow clean through 5mm 450 at 500m.
