Well.... I took it out to the range. The two days prior i spent hours and hours trying to remove hard carbon from the barrel.
I must have done 15+ or so extended scrubs with JB, and another 15-20+ scrubs with Kroil and a brush. I actually wore out the 2nd brush.
The directions on the JB container say to shoot the rifle and warm it up, before continuing on with a stubborn barrel. I will do that this go round.
I fired 3 decent looking groups of < 1.5 inches, The 4th group of H4895, +0.2 grains gained 8fps average and strung the bullets into a 3 inch, straight vertical group.
I then was all done with that combo, and switched to 165 grain Nos BT's. Nothing shot well after that.
I suspect copper, or carbon built up some place and ruined all shots after the 3rd group.
This time of year i don't have that much time to shoot.
I am somewhat spooked i am going to harm the barrel with this much scrubbing. After 30+ frustrating cycles, the patch comes out fully black. No sign of improvement or trend.
It seems the carbon is almost as hard as my head is. My dad took immaculate care of all of his barrels. Except for this one. It seems it was never cleaned. I am not sure if he purchased it second hand or not?
I am happy with the velocity the 16 inch DPMS barrel gives. I am shooting these 165-168 grain bullets between 2450-2500 and the brass looks fine.
Somewhat better than my fancy 20 inch custom barrel spits out running between 2500-2550.
Hornady brass seems a bit too soft for the AR308 platform. My range pick up Lake City Nato brass has worked the best by far.
The Starline brass has a good base for this platform also. I just can't get it size consistently.
Yesterday a nice fella was blasting away with his new 308 rifle. he let me pick up all 82 pieces of Lake City Nato 2021. Lucky me!!!
