Ok so here's the deal. I have an old Western Field model 712 in 222. I've been thinking about restocking it because there's a nice crack in the existing one. I've been researching who made my gun and I've found that Savage made guns for Western Field. A while back I was posting my load development for this gun and a guy had posted a nice write-up of the 340's which he said is what I had. Now that I've done some more reading I've found that it is an 840? Anyone have some info on the Savage 340's and 840's and their difference's? I know some people might say I'm wasting my time on this gun but it was my grandpa's so it has sentimental value. The serial number is 218077 and I can post pics tomorrow if that helps. Thanks in advance
