[QUOTE="benchracer, post: 1315886, member: 22069"] Once you decide which bullet you are going with, you need to measure the distance to the rifling, which will determine how much usable case volume you have. That may have an effect on which powder(s) you can use. RL-17 will get you to 2750 or so. RL-22 and RL-23 will get you very close to 2800. RL-23 is less temp sensitive than RL-22, but it is bulkier. RL-26 will take you to 2850ish with the 162 or 168 class bullets. It can take you to 2800 with the Berger 175 EH, as well. I have a #1A in 7x57. It runs right at 2700 with 160 Partitions, 162 AMAX, and 168 Berger Classic Hunters and RL-22. It runs around 2750 with 175 EH and RL-26. [/QUOTE]
