View Full Version : Milling down mold

I somehow managed to end up with two NOE 41 cal 225 grain SWC molds. Was thinking about milling one down to drop a 190 grain boolit. Will this take too much material off the base for it to shoot well? Anyone done this change before?

sell it and get another mold.i do not see any NOE molds I would mill down.no point in screwing up a good mold and have it be useless.

If a grease grooved bullet then it would have to go from base to bullet dia one groove at a time. and may not end up exactly where you want. Also simply milling off the base leaves a "long Nose" and shorter driving band section which could become an issue. I woud sell it or cast with the 2 together and buy what you want for the second.

If you have access to a lathe, mill the amount you are considering off a handful of boolits and shoot them. May tell you what you want to know before nibbling at the mold.

I skimmed the base of a 6.5 Lee `cruise missile` mould to reduce the bullet weight from 170gn to 150gn with no issues.

With the right Mold, this could also be a nice way to have a little lighter, non Gas check Boolit.

It will work...if done right.

I have a 311291 that I set up in my lathe and faced off the gas check shank and bottom lube groove, making the next driving band the bottom driving band. It is now, a 130g plain base that works in my .30 Badger extremely well.

If you have a four jaw chuck, it can be done in a lathe just as easy as a mill.

I like the idea of milling a cast boolit in stages to see what it's new weight will be at the various lengths. Should tell you exactly where to millthe mold.

I had a tool&die friend convert a RCBS 180FNGC to a 138gr PB and it works fine. But with your NOE I think I'd sell it and get what I wanted unless you're doing it yourself. I will say however it seems PB bullets with wider base bands shoot better than narrow base bands.

If that's a HP die I would definitely be interested in taking it off your hands.

I like the idea of milling down a few to try. I think I will try that first.

Not a hollow point, sorry.

I was just doing one the other day. Not to shorten the bullet or make a plain base but rather to repair / remove the galling on a used mold I acquired that cast bad fins on the bullet base.177976

The base of what started out as a really well made bullet mold had been scared to the point of uselessness. I lost 0.010" of base band but gained a mold. Rather than change the setup on the mill to use a wide cutter, I just made 10 passes and in about ten minutes I had a brand new, flat base for the plate to mate to. 100% fix of that area of the mold block.
There were a few other problems with this mold too. That can be another story.

A used NOE will generally sell for 75% -85% of new cost. I believe set up time on a lathe would be more than that.

Here is how I modified a mold in a mill:
