I use what ever Charley Hood furnishes.Pure lead or lead-antimony alloy.
Why prefer one over the other?
All I know is they are not pure lead.

Not much shoulder as the major punch diameter is .312". If you look closely, you can see it. -AlAl who made those punches they look they are straight ground with no shoulder Thanks
A close approximation: each 0.010" reduction/increase of me'plat (K.O. pin diameter) will increase/decrease G1 BC roughly 0.030.@alnyh @rgroI had a conversation today with a friend, regarding the diameter of the ejector pin.
It seems most dies are using a .062 while one of the steel die makers uses a .080.
Clearly you cannot close the meplat as small with the larger pin but does it have a dramatic effect on the performance of the bullet ?
Any suggestions? Somebody mentioned having one on the saubiers’ bullet making thread, but we never connected. I imagine any machine shop could turn one out…ok, I’ll look around town. I’ll have him make some ejector pin caps as well since I don’t have any of those either.GoWyo!: If you have the punches, the punch nut should be pretty straight forward. Even if you aren't going to use the dies, I'd sure encourage you to have this done so the set is complete.
I'm far from being an expert, but I believe the KO pin should eject by touching the outside of the meplat.How much are you guys closing the meplat? Just enough that it ejects reliably with the pin just inside the meplat or is the pin on the outside of the meplat? I plan on testing varying amounts of point up as soon as the weather breaks freezing, but curious where you have found the best accuracy.
You definitely have to " spin test them " spin them down the barrel and let the target tell you what works and what doesn't.When pointing up I like no more pressure than is required to push bullet out of die.
It's good for discussion and there are many things to be learned, but some Dude with a Funny Hat once told me about barrels and bullets....it's on the paper.

Just check the threading inside the ram. If it's a standard USS or SAE thread, you might be able to simply modify a hex head bolt as the punch nut.Any suggestions?

Morning, Dave. My Blackmon steel .30's use a .062 ejector. Not sure if that's always been the case over the years, though. -Al@AlNyhus @RGRobinett had a conversation today with a friend, regarding the diameter of the ejector pin.

Al here are some of punch assortment for 6an 30 some are Simmons an Dettch
an uirich dies
From my experience it will vary from one lot of jackets to another, I just finished doing 2 different lots of jackets/bullets. The first lot pointed up how I prefer with the punch barely touching the tip of the bullet and resulted in the bullet coming out of the point up die with very little resistance. The second lot required a die adjustment to where the I could see that the entire ejector pin mark contacting just inside the the meplat and this resulted in a little more resistance to eject. There was .015 difference to the base to ogive measurement.How much are you guys closing the meplat?

I’ve used @RGRobinett method to draw back some tougher lots of j4 jackets it does help.From my experience it will vary from one lot of jackets to another, I just finished doing 2 different lots of jackets/bullets.

With my 30’s, we found that there is something to be said in this.You definitely have to " spin test them " spin them down the barrel and let the target tell you what works and what doesn't.
