resizing factory cast bullets...

[magnumwheelman]

any issues in changing hardness or??? from resizing factory cast bullets that are already lubed...

in particular... I'm thinking about older cartridges like my 38-56 WCF Martini, where I've used a .375 barrel... & would like to shoot cast bullets in the gun ( so, lower pressure non gas checked bullets ) like sizing down .377 - .378" 38-55 bullets to .375 or .376"

I wouldn't think I'd need to re-lube them, but could run them through my lubrisizer & by only bringing them down a couple .001's shouldn't deform... any issues you guys can think of, short of waiting for the specific sizers???

I re size .312 bullets to .308 to shoot in my 30 carbine. No issues so far.

You should be just fine with what you've mentioned. (I assume you have the right equipment to do such sizing properly.)

Resizing already lubed bullets will minimize deformation or 'squishing' of the lube grooves. You run into problems doing extreme sizing of unlubed bullets.
