**600yd results posted** 300yd Blackfeather range report. 600yd shoot tomorrow
In preparation for a 600yd night shoot tomorrow, I took the Blackfeather with a JB Weld shimmed heel to the range to get a 300yd zero. Since I took the scope off to bed the heel, I had a very quick range session at 50 and 100. All looked good and I only needed a very small adjustment at 200.
I was running out of time so I only had time to rattle off 10 rounds at 300. I added about 3 minutes of elevation (just a guess) to see where I'd hit at 300. My first shot was about 4 inches high so I brought it back down about a minute to see where it would land. The next shot was just about where it needed to be elevation wise but was about an inch and a half left.
I did not make any more adjustments and the rifle seemed to settle in well over the next 8 shots. Those eight shots grouped in at 3.664" or 1.167 MOA.
Vertical stringing is GONE! The load I was using was commercial Winchester cases, 42.8 grains of 4064, a Remington 9-1/2 primer and a 168gr SMK seated to 2.812".
And just a reminder; this is a standard M1A that was built in 1994 and has a 52 year old GI H&R chrome lined barrel. I only added a Sadlak NM spring guide on this trip.
I also let a friend shoot the Blackfeather who just got out of the Army National Guard a few months ago.
I'm very pleased with how it's shooting. The CASM mount seems to be holding up very well with the Leupold MK4 scope and rings. Shooting tiny groups at 100 is just too easy. 200+ is really helping me develop some skills I'm not inherently familiar with using a scope and a bipod.
Tomorrow night will be a 600 yd night shoot. The line will be pitch black and the targets will be illuminated with floods.
