I’ve got a 38-55 that is a Winchester 94 newer rifle I had recut to this bore and it’s groove diameter is 376 I wanna load cast for it and get a mold the guy who did the job told me to stick with bullets in the .376-.377 range. I can’t seem to find molds that size but I can easily find the ones that are labeled by lee 375 win /38-55 .379 will these work or will I have issues that will mean my cast will be 3 thousands bigger. I’m very very new to this and I have so much to learn. Thanks
