Anybody have velocity numbers for Black Hills 68 gr. Hornady OTM from an 18" barrel?
How about 16" and/or 20"?

From: [i]Roberts GK: “The Wounding Effects of 5.56mm/.223 Law Enforcement General Purpose Shoulder Fired Carbines Compared With 12 ga. Shotguns and Pistol Caliber Weapons using 10% Ordnance Gelatin as a Tissue Simulant.”. Wound Ballistics Review. 3(4):16-28, 1998.[/i] 16" 1:7 twist, tested at 10': 2615fps but also note in a later test (for that same study) it has a listed velocity of 2939 fps. Ed looks like we'll have to run some through the chrony.

Forest, sounds good to me. I have the ammo and the 18" 1:7 SPR. Ed
