Here are some loads for 180 GR lead for the special. I would load them to the crimp line on the bullet and stay in the lower loads and the increased depth will not amount to much increase in pressure. Shooting them out of a 24 (welcome to the special club) will be like shooting a 38.
My preference for pen is the 180 TCBB and unique. Some time order some of those. That thing is a great load and very accurate. They are really nice in the Bulldog for the wife.
I also went through my Lyman cast lead book and sorry to say they don’t list a full wad cutter for COL.
My last order from Penn early spring during the worst of the crazzzzzzzz took 3 months. I talk to the man himself every couple of months and it hurts him to take so long but you have to understand that he is doing everything he can to fill orders. His is such a superior product sales are out the roof.
I’m just waiting for the .430 Thunder head like the 451. He has the molds but he has so many orders for his present list he doesn’t have the time.
