I started this load light with 27.1 accurate 2520 and went up to a Max load of 28.0 no pressure signs nice rounded primers no extractor marks or reject marks
Brass - Hornady trimmed to 1.515
Bullet - Nosler 140 grain rdf
Powder - accurate 2520 28.0 grains
OAL 2.255
This is out of my 20in sanders Armory match Barrel 1/8 twist with our 5r rifling.
And it grouped three quarters of an inch to 1 inch at a hundred yards according to my strelok Pro at a thousand yards is still going 1212. Fps with 450 lb of energy this is maximizing my small frame AR-15 to its fullest potential.
