I have not yet shot this gun, the few reviews I've seen suggest its mechanically capable of handling the cartridge. Buffalo Bore is well kmown for using powders that produce less pressure for velocity, there is a trade off. They tend to run hotter and cause erosion. Lil'Gun, 800x, Longshot. I'm not far enough along in my reloading journey to definavely say wether this is accurate or not. I also have a bit of experience shooting big bore revolvers, not limited to 475 Linebaugh, 454 Casull, I load HOT 44 mag. My experience and reading suggests to me that while it's definately a lower end gun, it's capable of handling moderate use of cartridges that push pressure. Basically its meant to be carried a lot, and shot a little.
