[QUOTE="AZShooter, post: 916064, member: 5219"] RL-33 yielded some very high velocities with the 110 accubond. You won't be able to duplicate the velocities as your barrel is shorter and isn't a 3 groove. Here is the rifle I used: Ruger action, 257 Weatherby: 28" #5 fluted SS Lilja 3 groove barrel, moly coated 110 accubond, .015" off rifling. Norma brass fed 215 match primer Need to mention that this barrel has over 700 rounds through it and is quite worn. This may also be the reason for these high velocities. Be sure to start low and work up to what your rifle/brass can handle. Original load 75.5 gr of RL-25 vel 3615 fps RL-33: 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 accurate 84 gr 3704 fps accurate 84.5 gr accurate but one case of four showed pressure this is max case capacity with drop tube [/QUOTE]
