Howdy
I have a Magma caster that is primarily for my wife & I..for a little bit of pocket money & to help other cowboys out at a reasonable price.
There is one Cowboy who says don't bother sizing or lubing, often thought of the lubing part myself, at the slow velocities we are shooting 'why bother'..maybe the rifle but the pistol should be ok.
I mean if the barrels are shiney clean & no pitting what's the chance of lead fouling..oh & the cowboy I mentioned hasn't had a problem..well at least that he's told me about.!
What say 'ye.... This is only in relation to guns in CAS..nothing else.
