Just fired up my new Lee 6 cavity 310 grain 44 mag mould today.
My RCBS Sizer Die is a .429
Front of chambers mic .429 on Super Red Hawk This should be ok.
It is sizing quite a bit all the way around the bullets. Bullets seemed to be mostly .430 - .432, as cast, and cast pretty hard. The water quinched ones went through the sizer REAL HARD. I only water quinched a few.
The RCBS 421 Top punch is way to small for the .366 Meplate. Looks like the 421 is set up for a maximum of about .300.
Wondering if the machine shop can recut the factory one to almost a Flat End profile to get it to work with the big flat point bullets? Out side diameter is .423, not much to work with tapering a new profile.
I just installed the heater, and was using Blue Angle for the first time. It took longer than I would have thought to warm up the lube to get it flowing. I did a complete clean up of my lubricator sizer, so it probably took a little effort to get the new hard lube flowing in a completely empty lubricator/sizer. The non water quinched bullets sized a lot easier after I finally got lube to flowing.
Decided to quit until I got the top punch issue taken care of so it is not putting a ring around the bullet noses.
Sugestions
