I believe it was Bismuth Cartridge Company that loaded a 3 1/2" 3 ounce lead load in Remington cases. They were on closeout for quite some time, but I never bought any. I still have some of the 2 7/8" ten gauge Bismuth loads that I bought for about ten bucks a box of 25 when a company I worked for was a dealer of BCC. The were loaded in Remington cases and roll crimped, a very nice package.
