| I am considering building a "guerilla sniper rifle" with a 16" barrel and a1/7 twist rate. Now, even though I am relatively unfamiliar with that specific profile, the medium weight sen on Ar15barrels.com seemed to fit the bill of both light weight and will remain relatively accurate. However, does anyone with experience with this weight wanna chime in on accuracy, both cold bore and with higher round counts? Also, are there any with chrome lined bores? Thanks for any help. |
| Hard to say. Accuracy results come with a few variables. It will ultimately depend on the quality of your particular barrel, quality of ammo, environmental conditions at the time, magnification, trigger, shooter skill, etc. You will just have to wait & see until after you get to shoot your set up. |
| Lets say, for the sake of argument, it's a quality barrel (as I don't know the makers of a medium wight chrome lined, I can't say) black hills 77 grain match, dry, sunny no wind day, at 100 yards. 4x acog , bill Alexander colt trigger, and I have been shooting f-class for a while. ( this is for a friend who indeed has been doing these things) |

This! The best smithed quality tube shooting shit ball ammo with open based bullets ain't gonna cut it. The fella that handloads shooting a say wilson,shaw production tube or other cheap tube and found a good load is gonna smoke 90% of the time the fella with a top line rig shooting shit factory ball ammo! |
| I have a similar goal. I just picked up a Daniel Defense 18" S2W barrel. It weighs 2.3 lbs and is pretty much the opposite of a govt profile. It tapers toward the muzzle. I'm changing out a 20" HBAR so I lose about 3/4 of a lb, 2 inches and get a twist rate that will be accurate with 77gr bullets. I'll post some accuracy info once I get it built. |
