convert GC to non-GC cavity on AL mold?

[bkbville]

I have a lee C309-113F mold for my M1 Carbine.

I was thinking of converting one of the cavities to plain-base; trimming the part of the mold that forms the GC stump.

As it's aluminum - any recommendations on what to use? Would a dremel be sufficient?

Yeah, a Dremel tool would do it but unless your far steadier than me I wouldn't do that to any of my moulds. I know going in what kind of a hack job I'd end up with.

I have done this with several of my moulds and it can be well worth while but I had it done correctly. It’s not all that expensive to have Erik to it right. Base band removal, driving band enlarging, hollow pointing and much more. Also he has a really good turn around time.

I sent mine to Buckshot. Dremel tools are for teeth.

A reamer beats anything else for this. It can be turned by hand with a tap driver if necessary, but even a hand drill or a little drill press will give a good job.

No slight intended to any of the fine machinists that provide this and other services here, but this can be done at home with the right tool.

.............Like this?:-) However a chucking reamer would also work with a carefull hand.

Your mold is in " Good Hands " with Buckshot ! !

He has removed the g/c shank on several of my molds. Top notch work ! !
