Hi all
Here we go... I am pretty new to casting and my experience with revolvers extends to creating 265gr hollow base slugs for my Webley .455 I don't size these as the cylinder does the job for me and the skirt then flares to catch the rifling in the barrel.
I am now onto my second project which is 160gr rn slugs out of a Colt Police Positive in 38S&W calibre. Having slugged the barrel (.335!!!) I am sizing my cast boolits to .355 in a Lyman 450. My question is: Should I be sizing at all or is the cylinder supposed to be doing this for me like the Webley does?
Cheers

P.S. the sized boolits drop into the cylinder but stop on the driving bands as I believe they should?
