I have been using H4350 in my 9.3x64 with 286gr Partitions. Has anyone tried RL19 with this bullet or 300gr SAF's. Thanks, Bob

Max loads of 4350 in my rifle are heavily compressed with 286 gr partitions. Rl 19 is slightly more dense but it is also slower burning.(close to IMR 4831). I think it will be too slow for the 9.3x64. what we need is a RL 17 halfway between the existing RL 15 and RL19.

Thanks Snowman. Do you think H414 or maybe AA2700 might be suitable for this cartridge? I am really interested in loads for the 300gr Swift.
