I probably shoot about 500 a year, I tend to use my .45 acp 1911 much more, and .38/357 but I can buy factory ammo for those much easier. Lately the commercial .455 ammo is harder to find, and very expensive. I have five hundred new .455 cases made from .45 Colt resized and trimmed down; and a few hundred Fiocchi cases, but they are weak brass and small pistol primers.
I like the idea of a turret style in case I get back into reloading other calibres; and was told that the RCBS die are compatible with all the brands of press. I'm getting older and don't want to be fiddling around with gear, I would prefer to get it as simple as possible. I don't have any preferences, but when I was reloading a lot I had a Dillon Square Deal B press that was excellent. I am getting older and not shooting as much so I buy commercial ammo for most pistol calibres, only .455 Webley is getting scarce and I need to keep feeding mine. Nostalgia and love of historical guns makes me hold on to the original calibre, I would never shave it. It is a 1916 Mark VI, RCN marked and in excellent condition. When I pass it on, the reloading gear will go with it so it remains functional.
