That's really similar to the Corbin press. Would love to find something that would work in rockchucker, not expecting anything for the progressive press. These rock checkers are extremely sturdy and would be fine for slugs.

No...not yet. Getting closer though. It's hard to believe how good some of the unlimited guns with good ammo are.Really great results Mike.
I wonder by this point if you have equaled the performance of the best 22rf BR rifles and ammo yet because it seems so???
Rimfire rounds actually have a lower bc than these. Most likely due to the additional rebate on the front of the bullet...but I can't say for sure.Mike,
Have you pulled .22 LR bullets from Lapua, SK and RWS rounds and compared their shapes to what you are making? I wonder if there is anything to be learned from their designs? You‘ve probably already been down that road? I’ve not pulled and compared any myself but some of us have noticed that Ruag (Norma and RWS) bullets seem to fly more accurately in windy conditions than SK and Lapua bullets do. How do Rimfire bullet BCs compare to your bullet?
The trick is incorporating the ejection operation into the press. That's a given with the rce or Corbin. I initially used the dies I made with a 50$ harbor freight arbor press. Worked fine, but not very fast.That's really similar to the Corbin press. Would love to find something that would work in rockchucker, not expecting anything for the progressive press.

Out of curiosity why does your slug have a shoulder or step before the boat tail? Altaros uses a smooth transition as does many copper jacketed boat tails that I am familiar with.
They need a rebate to be able to swage them reasonably fast. You need a 2 piece main die body to get a smooth boat tail in a swaging operation...but it's a lot more complex and time consuming.

That's interesting to know and seems to jive with my experience shooting both.A rebate boat tail design is better for group sizes at relatively shorter ranges due to intermediate ballistic characteristics as the slug leaves the barrel. This was the original reason for rebate boat tail designs. The drag will be increased slightly, but that would only be a problem at very long ranges.
