Snoman,<br><br>Please read and heed Chris's warnings. Even in a gun designed to fire both .410 shotshells and .45/70 cartridges the practice is of dubious value. The rifling on the barrel spins the shot causing it to spread very quickly. The EFFECTIVE range is very short (maybe a few yards max). I suspect that the TC was designed to give the owner an option in snake country, but the only time I've ever HAD to kill a snake, using a gun was not an option. Most often I'm content to walk around them, giving them a wide berth. Trying to shoot .410 slug loads through a .45/70 is... well, it's silly, but you probably knew that. Take care<br><br>Andy
