I started with a pair of 44Mags, one a Vaquero and the other a NMSBH (picked it up from a friend cheap). I then went to 45 BH Convertibles, then to a pair of 45Colt New Model Vaqueros (SS). I decided to convert to all 44/40 for simplicity, so bought a pair of slicked Piettas (nice guns). Trouble is these don't have enough room for my big fingers in the trigger guard and I set off the odd unexpected warning shot when hurrying. Dang! The NM Vaqueros in 45 Colt are back on the line until I get a chance to practice some and work the problem out. I need to get it sorted as i want to convert to Senior Duelist or Classic Cowboy.
I only shoot healthy loads, because the old 45 Colt BP loads were very healthy.
I will probably go to BP when I get everything sorted.
EDIT:
In Australia, the sissy gun rules. You need a special license to shoot anything bigger than 38s. The license is easy to get, you just have to ask for it basically and have been licensed for 6 months or more. For every 10-15 sissy guns shooters, you will get one big bore it seems. I must take note next big shoot.
