I need to load a couple of hundred rounds for a son-in-law that lives a few hundred miles away. He has an S&W 686, knows nothing about firearms, and can't get loaded ammo, hence the request. While I'm a long time rifle reloader, my handgun reloading has been somewhat limited through the years. It happens I have quite a few pistol powders and I can't tell you why since I only reload for my 9's, 38/357's and 44 mags. I do have a Dillon XL650.
He got a bunch of cast 210g SWC's, source unknown, best I can tell from photos. He's also order some Berry's 215 plated. I have no experience with plated bullets. I have tons of unopened 1# and 4# cans of Red Dot, Clays, 3N37 (4#), Blue Dot, H110 and H4227. I'd like to load up a few rounds for him to try, running them at about 1000fps. While I have a chronograph, getting together with him to try out might be a problem. I'd prefer to use the 3N37 and the Blue Dot since I have about 6# of those but I've been unable to come up with any published loads. I've read of the problems with Blue Dot but I believe that's related to cold and full house loads. All his shooting will be in mild temperatures so I have no concerns with that.
I'd appreciate any and all suggestions for mild loads with particularly those two propellants, but for any of the others I've got.
