This is a photo from the Riordan mansion state park collection, and it shows two kids walking their dog through “Milton” the Arizona Lumber & Timber company’s town that housed mill workers. The mill closed in the 1940s, and Milton is now part of Flagstaff.

I’ve been working to get this Ball & Williams made Ballard rifle from a nearby antique store, but in the meantime, I’m trying to figure out what bullet it would take so I can buy some display rounds to go with it after I buy it. Every source I’ve seen just says it shoots .46 rimfire, but I’ve seen .46 short, .46 carbine, .46 long, and .46 extra long. Considering how pricey the old .46 rounds are, I’d rather hear it from one of you guys than spend $30 on the wrong bullet
