[QUOTE="AZShooter, post: 710726, member: 5219"] I actually got 178 fps over the top load of Retumbo. Here is what I posted in a different thread: 6mm-284: 28" SS Bartlein 5R barrel 1 in 7.5 twist Original load: 58 gr of Retumbo, 105 Berger target hybrid seated .065" off rifling vel 3307 fps RL-33: starting load 58 gr vel 3074 jumped to 61 grs vel 3274 62 grs vel 3335 No signs of pressure, believe can add more powder. ---------------------------- Went back to the range for another session: 6mm-284 non moly Berger target hybrid worked up to 64.5 gr which showed slight lift with very tiny shiny spot on case head from Rem 700's ejector hole. (This is with 8 times fired lapua brass) 62.5 gr 3376 63 gr 3414 63.5 gr 3453 64 gr 3485 fps excellent accuracy 64.5 gr 3535 a bit warm max case capacity using drop tube ------------- Since then I have shot the 64 gr load and called it good. I get ragged holes at 100 yds. Going out to the Tucson Rifle Club to shoot at the 500 M Ram to verify. Ever since I switched to the 105 Berger hybrid this has shot well at the 500 M steel. I am certain it will do so with RL-33. Ross Old velocity with Retumbo was 3307 which was the highest charge of powder without pressure issues. RL-33 yielded a 178 fps increase! [/QUOTE]
