Thanks 03RN, being a fairly close neighbor to Rimrock I've shot thousands of his "pellets" both WC and the above mentioned SWC, good bullets and great service.
I shot Coopers 5.0 gr Red Dot load through a Chiefs Special years ago, in such a light gun it was like having a decent sized firecracker go off in my hand (ahh, youth!). It was nowhere as bad as shooting full power 357s through a S&W 360. That hurt! My small revolver now is a .357 mag 649, and it has enough mass to make Coopers load manageable. My bullets are also slightly lighter than normal SWC designs. I have a number of 38/357 hollowpoint moulds from different manufacturers. For some reason I actually enjoy casting with single cavity Ideal and earlier Lyman moulds, especially on a rainy, or snowy day. One other thing, Coopers load is exceptionally accurate in everything I've shot it in. Just like Skeeters load is.![]()

As I remember it Cooper suggested 5g of Red Dot behind Speer's 3/4 jacket 160g SWC. That's what I loaded and carried in my first off-duty weapon, a Model 60 S&W. The little booger kicked like a miniature mule. My biggest problem with it was my hands are too big to comfortably shoot any J-frame, let alone one loaded with that stuff. When the department let me start carrying a Government Model I paired it with a Commander (the alloy frame version) as my off duty weapon. Traded the M-60 off for something or other and never thought of Cooper's load again till this thread came up.

Pachmayr Compac Professionals take the fight out of most rambunctious J frames for me. I renew my plea for somebody to start making them from G10 or wood, please?
Okay, pretty please?

I took a caliper to the 158’s I have from Matt’s.
The OAL is very close but the base to crimp groove is about .110” less, so in theory I have a bit more space in the case. I’m not planning, nor do I desire to cram more powder in there, but figure the extra space may lower pressures a bit.
The only other difference I see is the hardness of the lead. Rimrock states 15, while the Matt’s show theirs as 11. The plan is to load a few up in a range using 2400 and see how it goes.
Working diligently to enlarge my group size.
I used to run that same load using the Lee C358-158-SWC in hollow point (the poor-man’s 358156).
It was indeed wicked-accurate from my three-screw BH. I cast from 50/50 COWW/pure lead.
Another goodie from back in the day was the 358429 over 13.5 of 2400 in .357 cases (seated over the front driving band.). I tried that one again recently from a six-cavity MP mould, but no luck duplicating the accuracy from my previous life, and it showed signs of excessive pressure.
On the to-do list for the next days off.
