Twobobbwana,you make a great point on the 450 NE. I have seriously thought about not stamping the barrels maintaing the option of simply extending the chamber to 450. The weight would certainly handle it well. However, I am going to finish it as a 45-70 and see how I like it. It is too early for me to tell since I can't even shoot it yet. You can't believe how anxious I am to get the receiver done. This project has taken so long but I am not going to give up until it is finished. I could shoot it now with the prototype receiver but it does not have bushings and I don't want to take the chance.----Bill
