Default Iron Sights at 300yds

well im getting ready to do the zombie shoot at mcmiller on the 25th. tossing around the idea of using my bcm upper but its too light for accurate off hand shooting where headshots on the zombies count and miss count against. still dont have a rifle buffer tube for my rra rifle lower and decided "what the hell just use the bcm lower"

looks a little odd, national match upper on a carbine lower, but it shoots damn well. its a RRA national match A2 with wilson air gauged cryo treated barrel 20". 1:8 twist wylde chamber with .050 front sight and 1/4x1/4 windage/elevation rear with .040 peep hooded rear sight. bolt is RRA chromed. handguards are freefloated. trigger is RRA 2 stage. sling is a turner sadlery biothane version of the 1903 rifle sling. i think its the best sling available for shooting off hand, sitting or prone.



ammunition is sierra 77grain matchking bthp over 24grains of RL15 using wolf .223 primers. brass is just range pickups of various makes.

temperature was 75degrees with 1-2mph winds from right to left. distance 300yards.

on this target the top three shots were sight in at 300yards. the rest was the same distance, i was using the dope for 69grain sierra matchking bthp. dropped it down 2 clicks and i was spot one for the next 4. i yanked one way to the right :/ but the first three could have been covered with a quarter.

while these shots were done from a solid front rest the point was to see just how well i could do under ideal conditions.

anyway here is the results

I like the heavy bullets too. I use a 75 grain Hornady Match BTHP. I have a 1 in 7 twist. I havent tried to push it out that far yet. But it will shoot clover leaves at 100 yards. But this is with a scope.

thanks. at that distance the target looks about the size of a grain of rice. even with a rest its not easy. RRA makes the best irons out there they track true and are predictable in their adjustments.

ive tried hornady but i get lackluster results at longer ranges.

with a 100yd zero i had to come up 18 clicks to hit zero at 300yds. from 100 to 200 was up 8 clicks

I have a removeable carry handle with the A2 sights similar to your rear sight. I haven't tried that kind of range with them though. Again, I am impressed.
