I have a Remington Model 14 Pump in 32 Remington Auto. I am trying to get a load for MBC 170 grain Hi-Tek coated bullets with .321 diameter. They are listed for the 32-40 cartridge, but should work in the Rem .32 which also is .321 dia.
I loaded them with data for regular copper hunting bullets, and got large puffs of smoke in all 3 loadings. The loads were with IMR 3031, IMR 4198, and Win 748. The estimated FPS ranged from 1830 to 2070, way too fast for even Hi-Tek coatings. I would like to get down to about 1300 FPS.
The only copper bullets I can use are the Speer 170 grain Hot core Flat Tip. They are very hard to find, that is why I attempted to use the ones from MBC.
Does anyone have any experience with Trail Boss? It is a bulky powder that fills the case with light charges, and gives low velocity. I am open to any powder, as long as I can get lower FPS.
