And I've learned a few lessons: 1. No...you can't use just any factory .30-06 ammo in this beautiful firerarm like the guy who sold it to me said. (I just removed the blown shell casing from the chamber - thank you Brownell for any easy-to-use extractor) 2. Finding the right ammo is becoming difficult to impossible. Yes, I can order some Greek ammo from CMP but the corrosivness I've read about scares me. Other than Federal "American Eagle" or Hornaday or CMP where do you find ammo for an M1? 3. Some have suggested reloading my own brass. I keep my .30-06 brass. Reading various threads or web pages reloading doesn't look impossible. The biggest hurdle is the Mrs. "Uh..honey. Remember when I promised not to get too deep into this M1 thing?" - LOL. If I go this direction are the right powder, primer and bullets readily available? Can I use my factory brass as long as the powder is correct? Everything I've read about using factory shells has to do with powder type and quantity causing problems in the M1. 4. I know there are M1's out there chambered for .308. .308 ammo is much more plentiful in our area. Can I buy a .308 barrel/receiver and simply subsitute it for the .30-06 barrel/reciever? Are all the other parts compatible? I'd be surprised (but pleased) if the answer is yes. 5. I've seen comments about adjutable gas plugs - they claim you can shoot factory loads in the M1. That's wonderful but what tells you how to adjust the plug for various factory loads - whether its Federal, Remington, Winchester, whatever I bought this rifle for many reasons - history (my father carried one in the Pacific), the feel of it and long range target shooting. Its got a new barrel, new stock, misc recycled parts - I love it. But I can't find ammo for it. Any and all comments are welcome. This M1 newbie is anxious to learn and get shooting.
