Can you see the thumbnail-pics? When I scroll over them they get bigger. Let me check that.

It is .38 special brass, Both are Missouri Bullet Co.'s BHN "Brinell" 12. The LRN's come in a box 'cowboy #11', the LSWC's say '.38 match'.

For this test I was using a two hand hold, sitting in a chair, elbows resting on the shooting bench. I shoot .38 special a lot so the hold, trigger pull, etc is only as consistent as I am - (laughing) - the gun and ammo is clearly capable of more accuracy than I am.
