Thanks guys for all your input.

Hugh, I forgot to mention that your reload results are fantastic. I will be happy if I get a one inch group at a 100 yards.

2152hq, Your added info is good to know. It may come in very useful in the future. How can I measure the headspace?

Charlie, I definitely do not want to put myself, bystanders or my carbine in any danger. I will do a lot of research, and tread very lightly.
