My bro has the 650 Dillon. That is a nice machine with case and bullet feed(I think). He uses it for his .45 Colt, .44/40 and .45 ACP ammo for Cowboy Action.
The .45 ACP is used in the "Wildbunch" group.

I haven't shot IPSc for 38 years so am out of "touch" with things associated with that sport.
The sport turned into a Race Gun game here so I lost interest.
I started off in IPSC with my 4" Model 29 back in 1975, switching to a 1911 in the early 80's, then selling that pistol and quitting the game.
I used a small & slim, hard leather cross draw holster back then, that went with the pistol. Not sure they are even allowed nowadays.
