Gas gun LVR max

[rickt300]

You can work up to 31.5gr under a 120-123gr cup and core bullet in the AR-15.

Your gas system length, port size, and plug dwell will be bigger factors in how much charge weight you can go with since LEVERevolution is slower-burning.

I worked up to 32.2gr in the Howa Mini bolt gun with 123gr SST. The biggest jump in velocity I saw was when I went from 31.0gr to 31.3gr with a 62fps increase.

31.0gr is a good cut-off in the AR-15 under 123gr at 2.230” to 2.260” COL, depending on the bullet.

123gr SMK and 123gr Scenar are longer than other 123gr bullets, so you will need to account for COL and projectile intrusion into the case.

If you’re loading Hornady 123gr ELD-M, A-MAX, SST, or BTHP, from a known chamber, you’ll top-out in that 31.0-31.5gr range.

31.0gr gave me 2534fps from the 22” Howa barrel spitting the 123gr SST, which is plenty of performance.

I have heard LVR can be dirty in an AR. Main bullet I will be loading will be the 120 gr. Ballistic Tip which has a longer bearing surface than the match style bullets. Will start a bit low and work up in new brass.
