Started off my competitive shooting career with a Fulton Armory CMP Upper with a 1-7 Krieger. That beast was a hammer and took me to master long range. My go to load was 24.5gr H4895, LC brass and a 77gr Sierra at mag length. I would load the same recipe with 75 AMAX past mag length for long range. It was an honest 0.5MOA setup if I did my part.
Back in 2014 I built my first AR15 upper, a shorty carbine. 16" 1-7 WOA barrel with a mid length gas system. I used a Yankee Hill back-up flip front sight with gas block included, I don't think its adjustable. Need to go back and look. I've ran my old leftover reloads thru it, and accuracy is just "ho hum" 5 shots 1-1.5" at 100 yards with a 10X scope. Not terrible, but not what I had hoped for either. Occasionally can get 3 or 4 into 0.75", but there is always a flyer that will open up a total group. I'd love to use this for some short course NRA prone practice, but at 1.5MOA, I don't trust it well enough for proper feedback on a scoreable target.
I'm going to have to dig out the Zediker books again.
What are some tips you guys do to squeeze on sub MOA in your AR15/carbine platforms?
Can't really tweak seating depth for a mag length set up.
Do you tweak your charges and primers until you hit a node?
Going to be building a 6ARC once I get a barrel that's on order.
Figured Id better re-study up on AR15 loading before I tackle that one.
