I just bought a 410/45 barrel for my contender. I have read that they suffer accuracy because of the length of the cylinder bore. I was just thinking could I load the longer 454 cases I have with a light load...but load them shallow to make them closer to the 410 length to give me accuracy from the 45 lc barrel? I was just wondering..in my head it makes sense...but then again that's why I am asking. I already reload for the 45 LC. I thank you for any help you can give me.
