Well I was looking at a semi auto rifle (chamberd in 30-06) and I came across a 742 BDL (7400)Woodmaster Deluxe with a Monte Carlo Basket Weave stock going for $280. I havent gone down to the store to look at her yet but I called in to see what kind of condition it was in he said very good. I have heard stories about jamming and some about them being perfect guns. My son will be using this rifle for deer season next year if I get it. I want to know as much as i can on this rifle, except the problems with the bolt waring the rail down cause that will be the first thing i check on that gun.
I would HIGHLY recommend you shoot the rifle in advance of buying it if possible, or get assurance of being able to return it if it turns out to be a lemon. Honestly I don't think you can go wrong at that price. Even if it malfunctions or produces poor accuracy, it can be fixed. I've had dozens of the 740/742/7400 brought in to the shop over the years, so if you need any tips, let me know.
One of the main problems is the extractor. It is relatively weak. If the chamber gets rusty/pitted the extractor is not strong enough to do its intended job. If the chamber is clean and smooth the rifle should be OK
Stay clear of reloaded ammunition. I blew the bolt out of a 742 30-06 on the first reloaded bullet I tried. Although, back then I wasn't reloading for myself so I not sure what went wrong except it blew up a week before deer season. I guess I'm just a little jittery when it comes to 742's.
