problems with mold fillout with lee 148gr TL wadcutter

45 2.1, thanks for the idea. I'll combine beagling and boiling for one more session and see what happens.

Matt, it's yours if I decide to sell.

OK, alloy isn't the problem. I broke out a NIB 429640 to cast up some samples for another member and got good boolits as soon as the mould warmed up. I boiled the offending group buy mould in Dawn and water while I was casting, and was very surprised to find it turn a very dark color, particularly in the cavities. I'm hoping this is a good thing?
Beagling and a final casting session may happen tomorrow.

Maybe I rediscovered something the other day.

Got a couple new Lee's, a 2 and 6 hole .45's. Haven't warmed up the 6 holer yet.

The 2 is a 250gr REAL bullet, both the same.

They cast good the first session of about 300 or so. Very few rejects.

Second time the propotIV was dispensing about half flow. Seemed to run good, so I kept casting. Fluxing & scraping the insides. Tripped and adjusted the needle many time's and just couldn't get it to flow.

Had over 50% scrap.

I hate to stick things up into the jet. Just had this pot rebuilt a yr ago because I wrecked it doing that.
Finally I got a piece of aluminum welding rod and pushed it up in the jet while it was flowing. Sure enough that did the trick and it's back to making good 'uns everytime.

This might be something to keep in mind. You've gotta have a full, or near full flow or they won't fill out all the way, at least that's the case this particular time.

Wish you well,

George
