RGC Posted February 9, 2020 Share Posted February 9, 2020 Anyone using 356 diameters in 9 Major? Looking to standardize bullets w my 38SC. Link to comment Share on other sites More sharing options...
zzt Posted February 9, 2020 Share Posted February 9, 2020 I don't because my .355" bores love the 115 HAPs I'm feeding them. If you wanted to use .356" heavy plate bullets in both, that would work up to 1500fps. I've met people who shoot the 125gr .356" HAPs in a 9mm. I have no idea what their bore diameter was. You should slug your bore and find out what the actual bore diameter is. It may be .356", or it may be higher yet. Link to comment Share on other sites More sharing options...
RGC Posted February 10, 2020 Author Share Posted February 10, 2020 Thanks. I was thinking of running HAPs...and looking to get rid of 3500 .356 Zero 125's at the same time...but I may just dump them or reload some grinder weekend loads with them and move directly to the 115's for 9Major...

Don_B Posted February 10, 2020 Share Posted February 10, 2020 This may not be true for all barrels but I bet you will find that most 38 Super barrels are.355, same as the 9mm. Link to comment Share on other sites More sharing options...
