I cast/handloaded .357s for decades for a Ruger OM BH with a now 40-yo RCBS carbide sizer.
Now shooting S&Ws a lot, they seem to have tighter chambers. Even after renting a reamer and opening throats to .358, my cast boolit handloads are tough to chamber, even with boolits sized .357. This is Starline .38 spl brass.
Before having any chambers recut, I thought I’d try a new size die.
Who makes the tightest one?
Thanks.
