I used to use RL-25 but when RL-33 came along I gave it a try.
Custom throated (shorter) Pacific tool and gauge reamer
28" SS Lilja 3 groove barrel
moly coated 110 accubond .015" off rifling.
Original load 75.5 gr of RL-25 vel 3615 fps
RL-33
starting load 76 gr for vel of 3318
jumped to 80 gr 3432 fps
81 gr 3525
82 gr 3559
83 3625 which slightly faster than old load with RL-25
83.5 3674 fps shot well two shots were same velocity
84 gr 3704 fps shot well two shots were same velocity
84.5 gr 3735 this is max case capacity with drop tube
Your results may vary. Please work up from 80-81 grs.
WOW...
Smoking loads.
What kinda groups were you getting and were there any accuracy nodes along the way?
