I bought a box of Montana Precision Swaging bullets for my 40-65 WCF. Contrary to the company name, these bullets are cast, and very poorly cast at that. I've been trying out different bullet weights and styles prior to buying a mould or two for my rifle, but the money spent on Montana Precision bullets turned out to be money wasted. Severe flashing is on about half the bullet noses. All of the bullets show wrinkles and poor fill out from pouring lead that was too cool. I would have thrown these back into the pot, and I would be too embarrassed to consider selling them, but it seems Montana Precision may have a higher shame threshold than me.
If it was just one or two bullets, I might understand. However, when companies start shipping entire boxes of bad bullets, I figure I should warn other reloaders. These bullets are barely good enough for fire forming your brass.
If you need to buy your lead bullets for BP rifles, buy Lyman. Their bullets are much, much better quality. I bought some of the Long Range High Performance Lyman bullets, and they look pretty good. Not as good as home cooked, but pretty good.
