Armalite AR10 300 Ultra SASS (my factory 300 SAUM)
I started out shooting the 210 VLDs at 2930 fps with RL17 but was getting some extractor sweep so I dropped down to find a new load with 190 VLDs and I'm sending them at about 2915 right now with no pressure signs. I see no reason why you can't achieve your goal with RL17 and a 24" barrel.
I might revisit the 210s or 208s with RL33 and see how they shoot...but with a semi auto...I'm JACKED to be sending these into right around 1/2 MOA groups.
This was my first 3 shots past 100 yds after 12 test rounds.
I fired 4 groups of 3 to get a rough estimate of velocity and accuracy...and this was the result. I have since taken it out to a mile with the 190 VLDs and it's an absolute performer for being essentially a 100% stock Armalite. (trigger and barrel are factory)
