RE: 7400 Remington
I like the 7400 and th e742. I have hunted with a 1961 Remington 742 on and off over the last 30 years and I have killed hundreds of whitetails and hogs with it. The 7400 is similar. I took a nice 7 point with my 7400 this season on opening day. 1 shot, he dropped in his tracks.
I can tell you now though, you MUST keep these rifles clean. Especially the slide rails for the ejector. No oil build up on the slides! Also once a year take them and have an ultra-sonic cleaning done on them and have the firing chamber polished.
