Hi,
I have an RCBS 38-150 (KeithStyle?) SWC mold that I'm having a little trouble getting the base of the bullet sharp! This is a great mold and the bullets are VERY accurate even with the ones that the base is a little rounded. I use this bullet in .38spl and .357 mag. with excellent results but this bullet coming out with a soft base every now and then bugs me!
I've tried putting the heat up or down.Poring the mold close to the nozzle or farther away(I use a bottom pour pot) using mold release not using mold release,ect,ect. I'm sort of out of ideas,also the bullet is sharp on driving bands and nose,only soft on base??? Hopefully some of you might have some ideas on this. Thanks!
