I think I would like to try the Missouri Bullet Company (MBC) IDP #4-XD bullet (.45 ACP .452, 200gn RNFP) for shooting IDPA and USPSA. The only quantity of powder I have on hand is WW231. Could anyone recommend a powder charge of 231 that would yield about 825 fps? I need at least 825 fps velocity to meet the minimum IDPA power factor of 165 (bullet mass x velocity / 1000).
For liability reasons, MBC cannot give out powder charge information, but others have written in with the charge levels they use. Unfortunately, I cannot find any data for 231.
From my Hornady and Sierra reloading manuals, I could take a guess at about 5.9 grains. Does anybody have any data for that particular bullet using 231 powder? I do have a tiny bit of Unique I could try, but no quantity for any decent number of rounds. Thanks.
