[QUOTE="Brent, post: 27058, member: 99"] QH, My printer is out of ink or I would print, scan, then email you all my data collected for it. That's the only way I can pass it on other than typing it all down. I'll do it the end of the week when I get a cartridge back in the printer though, it's interesting stuff. The nice thing I noticed with this powder and the 180's was the stable and steady rise in pressure and MV, even up at the top, and that's usually the case anyhow but, it can get weird on you with some combinations or some powders especially. I haven't looked at any loading data for the SAUM so, I don't know how the WSM compares in powder charges for the same bullet weights. That would be the best guideline when looking at this data here for the WSM, as you probably can figure too. Is there a simple trend of a grain or two less powder accross the board for the SAUM than the WSM? I know there ain't much diff between them. I can't remember if he was compressing the powder or not, I'll find out when he gets home bout 9:30 tonight... I think he was and it was pretty full, up in the neck I think. I just can't remember though. [img]images/icons/rolleyes.gif[/img] A slightly faster powder may benifit you better with the "somewhat" shorter bbl and compression if the OAL creates an isssue with that. I have noticed pressures move up higher when seating bullets deeper, and almost NEVER when out farther, even on or into the lands. Just what I've observed with the psi equipment. I always seat mine up in the lands and back away slowly with the OAL watching the pressure come up slowly when working up a load. .050" - .100" seating depth has shown between 3k - 5k PSI change pretty much accross the board an any cartridge I've tested, and at a top end load that can mean maybe "too" much pressure. 50-100 fps pretty much falls in line with a 3-5k psi increase or decrease too, very, very close to it anyway. You might try RL15 or a Hodgdon Extreme powder of comparable burn rate and compare to RL19, you might come out with less disturbance on the bullet from less muzzle psi on exit, maybe better MV in the 24 incher too, I'm just speculating.
