(Would echo Dan's concerns regarding pressures and RL-16!)

HBN - very interesting! Thank you bowfishin.

I'm pretty much wrapped up load dev with RL-26, thought I'd post to the group if anyone is interested.

Calibrated QL Ba for this lot of RL-26 is 0.370, near exact correlation with LabRadar MVs between 60-95 deg F. Chamber pressures max 64K psi (42.0 H4350 calculates to 60K). Precision equal or superior to my best H4350 loads (~0.3 moa @300), but making 2975 @85 deg F, sd 9 over 15 shots. Happily, no POI shift with/without TBAC 7". Attaching drop DOPE (mils) obtained this past weekend out to 800 with the TBAC. The external ballistics with pointed 140 Berger VLD-Hs are pretty skookum. 1000 ft-lb energy at 1100 yds. Theoretically goes transonic in the desert at at 1750 yds (?!?!) Weather permitting, I hope to get 1000, 1250, 1450, and 1800 yd DOPE in the next couple of weeks, curious to see if the regression curve holds up.

Your one of the few on here that knows what Skookum means ;-)
