The far right is the 180 XTP, so far the most accurate. I did pick up some 180 FMJ from Rocky Mtn Reloaders for a good price. They shoot pretty good, not as tight as the XTP. From my cowboy action days, I have some 38-40 180 gr. RNFP soft lead bullets (far left) that I haven't tried yet, but should do OK in the KKM barrel. Sounds like a good way to shoot up surplus .38-40 CAS bullets. Loaded round is a truncated cone lead, but I don't remember which one, probably 180 gr.

I’m curious how the 38-40 bullets work out n the 10mm. I’ve kicked around trying them but the 180xtp shoots so good I’ve not got away from them.


I’m using 9.2grs of LongShot with the 180xtp. It clocks 1348fps from my 6” storm lake barrel.

When I die I hope I don't start voting democrat.
