Ok so I'm trying to come up with a plinking 9mm load for my Canik Darkside. It seems that loads for my Shadow1 are too long for the Canik by quite a bit. I have cast 143gr No Lube Groove boolits and the powder coating actually went on a little thick. I'm using Win231 powder and I started with 4gr but because I have to seat them to 1.055- 1.06 as opposed to around 1.10 for the Shadow to get them to past the plunk test it feels like the load has a bit too much recoil. Is it because they are seated so much more deeper? Does anyone have data for this particular boolit with Win231?
