Anybody here that has any experience using cast boolits in the SIG Rattler 5,5 inch barrel in 300 BO? The rifling is 1/5 inch which I am guessing will be a bit of a challenge for a cast boolit.
My primary thought is to cast the NOE ”Taco” bullet (225 grain) and use them for subsonics. That means about 1000 fps so I am hoping it might me doable with a cast boolit?
The boolit will be PC and probably around 12-15 BHN. And if there is something wrong with my thinking there I am very open for suggestions
Link to the bullet in question. I am planing to use the TL-version (recommendation from the designer) even if I am going to powder coat.
