I am in Caldwell and know of a handful of fellow M1A/M14 shooters. There are more than one would think, if you could somehow get them all together all at once.
BTW, gun show in Nampa this weekend. I will be there early Sunday. (There will be an old bald guy that walks with a slight limp and wearing a hat with a red flower on it. That may or may not be me.)
I don't know what the Emmett club has in regards to military rifles. Nampa club already had their "Frozen Chozen" shoot for this winter, I think. Parma Rod and Gun club has had military rifle shoots in the past. I have shot in a few of them a handful of years ago. (Admittedly, I don't keep up much with that club, as they have raised the membership fee to way above "What?" beyond "How Much?!!", past "You're kidding!!?" almost up to "No, I meant for only ONE YEAR!!!". For the average guy that goes out and sights in his deer rifle, and plinks away a few times a year, they are WAY WAY too expensive. Nice range, no argument, but for the average guy.......drive down Pearl Road a mile or two and pull over. There are still places to get out to 1000 yards. Free. I do it all the time. (I actually have a "No Tell'em" ravine that another guy and I marked out to 700 yards. Shhhhh.)
If you need any info on the local gun shops, etc, PM me.
