[QUOTE="elkaholic, post: 2523570, member: 13833"] 300 MEGA UPDATE: Not many people have submitted data yet so thought id put up some RL26 results on pressure/velocity. I had predicted early on that I thought the MEGA would reach 3050 with RL26 and the only info so far was Ryan Hovees data with H1000 which he said showed pressure signs a little over 3000 which sounded about right. My friend put a Ruger#1 together with a 26 ", 10 twist Lilja and lives 5 minutes from me so I ran over there tonight to shoot the only (3) 215 Bergers I had. I guessed at what might be a max charge, and started lower with 1 grain increment jumps. As it turned out, it looks like I should have loaded 1 grain higher. I measured the web on each case and all 3 rounds measured the same, so I didnt reach that normal 1/2 thou increase you get when pressure is reached. All 3 rounds kicked right out which is saying something for a Ruger#1 which isnt known for strong extraction with no cam action. [/QUOTE]
