I just bought a SB2 30-06 as a first rifle for my son. ... I've been reading about them quite a bit and have come across the odd person that said, "The action would come "unlocked" during recoil and would always break open resulting in very poor accuracy." Sounds down right dangerous to me. Is it just a case of not closing the action firmly. How easy is it to accidentally disengage or not close properly. Anyone care to comment
"odd person" is an apt description, the only time, I had an action pop open is when I've purchased barrels other than those fitted by the factory. This is easily remedied, by either switching the barrel to another frame, or doing a little fitting work. I've been lucky, since I have more than one receiver, and usually find one that fits properly. I also second the advice to make sure the shelf and latch are clean and dry. It also helps quoting quick to: "Read the FAQ's"

.
BTW, I'm not one of those that have had problems with Remington made Handi's. I recently sent back a CBA receiver to have an extra barrel added, and requested the factory trigger job while the receiver was there. Boy, was I surprised! The trigger breaks as cleanly or even better than some of my older Gardner H&R's and NEF's.
H&R's whether built in Ilion or Gardner are only as good as the people who work there. My understanding is that
most of the H&R staff at Gardner, moved to similar jobs at the Ilion plant. My contention is that you can get a lemon no matter how good the QC is. Ask my brother in law, about his Mercedes, or a friend of mine that swears he will never buy another Honda as long as he lives.
