That boolit right there is one of the most accurate 9mm designs I've used.

This is another MP mold, and it is excellent. I have not loaded any in my 210 yet, but it has been excellent in my Browning and S&W 9 mm's. It also works very well as cast in 38 Specials.

In my P210 TGT I have fired about 3,000 Lyman 356402 through it. No feeding problems at all.

You’re asking a question only your pistol can answer. Two identical pistols, one serial number apart, may or may not like the same load. In all likelihood, most any mould would probably fill the bill if you play with different powders and charges. Personally, I’d go with a Lee six-cavity and do some experimenting with components.

No experience with a Sig 210: however every 9mm brand (my son's & my friends) loves the MP 359-125HP or same boolit in a solid =MP359-130.

There is a GB for this one that is now in the discussion stage as a rerun. I have the 8 cav. solid now & signed up for another to salt away (insurance). I'm also seriously considering that they add a 4 cav. brass HP. I like this boolit!

I have 2 other 9mm molds, but this is the one that everyone prefers.

The only problem with GBs is no telling when you'll get the mold.

The 275 clone is more of a 38 Super boolit.

I have the mold. I have yet to be able to make a working cartridge with it. That type of SWC boolit just has too much nose out front. That requires extra deep seating in the case. That swages down the base.

This 275 clone is going to have to shoot some tight,to beat the 358480!
