I tried using my LED work lights and got nothing, half the time it would register the other half I'd get errors, tho I only gave it about 20 shots in total before boxing it back up.
I just got done with the first round with the chrono.
.308 Texan settings:
Stock hammer and 1 hammer weight, total 109 grams. (Matt at R&L told me his Texan and another .308 Texan in the shop had 2 hammer weights but I've sent my Texan into Airforce and it came back with 1 hammer weight just like it went in with.)
Ammo: Hunters Supply 154 grain SP, ACTUALLY 10.15 grams/156.68 grain - I weighed out about 50 rounds and used 20 that weighed in from 10.14 grams to 10.16 grams range.
Power setting: 100% max/can't turn up anymore.
