I use WSF for most loads in 10mm and 38 Super in 1911 Dan Wesson custom Razorbacks ser# xxxxx01 and 02 IIRC it was 7gr for 180gr 10mm, and about 5gr for 38 Super and about 8g 1500fps in 38Super. Needless to say the one magazine that I shot penatrated a fairly new 8" seasoned 8x8 oak post. That was about 3/16" better then 10mm SD load.

Also I hope you're not really crimping the bullet, just squeezing it till it almost start to roll the case as these are straight wall cases and head space on case behind the bullet, unlike 9mm which is lightly tapered and does not space on head of case.
