I have bought a couple of bore rider molds and chose a tapered front band when on the design software.
Should the bullet, once cast, have a smaller diameter on the front of the band?
I was thinking of having some taper to the front band to assist with alignment once the bullet enters the rifling. The band was selected to be long and no crimp groove to assure good sealing and bearing surface too.
After casting the bullets and then sizing them to .285", I noticed the front band is completely sized and I don't have the taper I was looking for. The design should have had .002" of taper and the bullet tolerances was ordered to be +- .001". I should s3ee some taper if the mold is cut correctly shouldn't I?
Maybe its just a waste of time...?
Just curious now. The bullet is a pain in the tail to run anyway.
135gr RNFPGC at .285" is the specs of the mold.
