I'm useing 5grs WW231 with a Zero 125gr HP , Nice easy load that can be dropped to 4-4.5 grs. I have 2 Kimbers. A Pro Carry HD and a Stainless Target II in 38 Super
I run 3gr of bullseye behind a 147TC, and 3.4gr behind a 150gr LSWC, both recoil VERY light and right around 1000fps from a 6". 1911 with a 10lb recoil spring.
