Nate Goodfellow was making and selling cast boolits. He had 230rn and 200lswc. I can't find his email addy but you can probably post something on the Parma board to get in touch with him.
I use an H&G type 200lswc in all of my .45's, never had an issue. Load them to 1.255" and crimp @ .469/.470 and you should be good to go. Unless of course you have a short throated Glock. Then you might have to seat with the shoulder of the bullet even with the case.
Don't load them with the shoulder even with the case for a 1911.If you want to try LSWC's before you buy a bunch, let me know. You can shoot some of mine after a match. Be fore warned, if you are an accuracy nerd, my load is addictive.
