I came across some 300 Bear Creek Supply 38spl 158 hardcast swc.
These are completely smooth around at the base and have no gas check or lube grooves. I am also unsure if they are lubed or not. They are dark grey and appear shiny and satin like, almost like they are coated, so maybe they are lubed?
I have 700x and 231 to load with. I will most likely use some for target loads but would like to work up some to have on hand for woods defense.
Should I approach this bullet like any other cast load? I am only concerned about the sans gas check and if I may need to load lighter or hotter because of that? I'm assuming that without a check the load will have less drag and pressure?
I was going to go off of Lyman data for a 160gr, 3.5-4.9 of 231. I don't know if this is off base, so I wanted to ask first.
These will be used in a 442 and a 8" rifled shotgun insert.
Any recommendations? Any experience with BCS bullets?
Thanks
