I exchanged the first one because of the faulty screws for the buttplate, onther than that, the first one had total case hardning on the reciever and a little nicer wood. This one has perfect screws, but the wood has a little less grain and no lock. I have only put 1 box of Remington 405 Geen Box thru her, very nice load to say the least!! I hate the double crimping they do though on the cases, looks goofy. Yes, hardcast 405`s sound pretty interesting. I am going to buy a box of PMC Cowboy 405`s and see how they do, and they are less money, although I know the velocity is less. Will the lower velocity PMC Cowboy loads kill a Deer up to 100 yards? Thanks-Jack.
