Terry, wish I was there to see the smile on your face. I have an HK, and AR, and the M1A is still the favorite. Get some targets from FRED, found in Shotgun News.
Remember this:
2-3 for 300
3-4 for 400
4-5 for 500
These are the "come-ups" in clicks for shooting after getting a zero at 100.
You're gonna love it. The way a battle rifle should be. All the best aspects of the Garand, with a 20 rd. Magazine. Speaking of those, AVOID the USA brand. They're crap. Get the GI issue mags. They're $40, but worth every penny.
Put in another post when you go light it off!
Slim, out.
