[QUOTE="WAMBO, post: 844333, member: 299"] Your 338 Raptor sounds and looks very impressive, kudos on the great work you are doing. I have a little experience with RL 33 as I have been doing some testing with it in the 338 LM you built for me and at similar pressures I'm getting close to 100 fps higher velocity over Retumbo using 8 grs more powder. 91grs of Retumbo gets me 2780 fps and 99grs of RL 33 is 2878 fps with the 300gr Berger Hybrid. I haven't had the chance to figure out anything about temp sensitivity yet as I just started testing but hope to see how it performs this winter compared to the 90+ temps now. [/QUOTE]
