The 44spl is a fantastic cartridge that bring a lot to the table. I've owned and carried bulldogs since the 80's along with reloading for them.
IMHO:
A 180gr to 220gr bullet's are better suited in the snubnosed 44spl's. Same goes for a lead or pc'd bullet over a jacketed or plated bullet. Every couple of years I do updated testing with bullets/loads in a ca bulldog. Tests I did 2 years ago.
The bullet on the bottom left was cast from a h&g #142 mold with the old style hp pin. The h&g #142 is an excellent bullet, h&g's version of the Thompson bullet lyman uses, the 429215. The h&g version casts a 220gr solid nosed swc and a 200gr hp swc.
The top left bullet is also impressive, it's a lyman 429422 cast bullet. It's a hollow based version of the keith 429421 swc bullet. I used a forster hp tool with a 60* center drill to make a hp in that bullet. The end result is a hollow based hollow pointed swc. Decades ago ww came out with their 38spl "FBI" bullet/load. WW used a hollow based hollow pointed swc for their 38spl/fbi load.
My 44spl hollow based hollow pointed bullet.
A side view of that same expanded hp pictured above. The hb not only compressed (it's supposed to) in expanded from being a hb bullet.
I really like the h&g #142/Thompson design and this year I'll be doing testing in the bulldog with a Mihec custom mold, a spinoff of that Thompson design.
I bought a 2-cavity of the older version that casts the bullets pictured above. 3 weeks ago I picked up a 4-cavity mold with updated pins. The updated version will also cast a 180gr penta point hp. I have that 4-cavity mold setup with:
1 large hp 180gr
1 penta hp 180gr
1 small hp 188gr
1 cup hp 192gr
I'll stay with 2400 for powder. A lot of reloaders don't know it but 2400 not only holds it's own in the snubnosed 44spl's, the pressures are low compared to loads like the "Skeeter 7.5gr of unique/245gr lead swc load". Those 4 2400 loads from 2 years ago pictured above are run in the 18,500psi +/- range. While the "Skeeter" load is in the 23,000psi +/- range.
Anyway you start getting a 180gr to 220gr bullet doing 900fps+ in a snubnosed 44spl, you'll find that they tend to shoot to the point of aim along with putting the smack on anything they hit.
