Hi; I'm new to reloading, about 1000 rounds so far. I would like to lighten up the recoil of my DK1911 Smith & Wesson 45. I'm using 4.7 grains VV320, Lasercast 200gr LSWC's at 1.250 & this is minimum according to VV. This gun has never had a jam right from new, never failed to extract & is accurate, I would like to lighten the recoil though. I see that when you go to a lighter bullet much more powder is needed, why? VV cautions against loading with less than minimum listed charge. I want to stay with Lasercast as I get no leading & the VV is great. I can drop down to a 180 LSWC, it just seems that with more powder I'm not accomplishing much. Thanks, Randy
