Here are some "published data" from Guns Magzine Oct. '96 (I know, magazines are really biased, but just bear with me on this one. This is the only reference I can find at the moment
): H-S Tactical take-down mode in 308 Win. 5 shot group with Fed GM (they didn't even match the ammo with the rifle. They simply shot it! This group was shot after several groups without cleaning) was 0.442" @ 100 yd. That's indeed very impressive all things considered. They also noticed that the very first round shot high left, and it seemed to be a pattern for this particular test gun whenever they reassembled the barrel to the action. Remenber that every single rifle will behave differently, so this is by no means a pattern for other guns.
The next group they shot was shoot-reassemble-shoot, and I
assume the same shooter shot this. The result was 1.37"(not bad, consider many "fixed barrel" rifles out there won't even shoot a group like this), and the shots hovered around its initial zero (that's really good. This prove the precision H-S has on this mechanism). However, all mechanical devices would eventually wear lose when used repeatly (i.e. the interrupted thread).
Overall, the take-down model is properly the "smallest" full-size rifle you can find (a complete case measured 23"x17"x9", and it's ready for action in minutes), plus the good reputation H-S has gotten over the years. The only drawback would be the cost (the quote for that test rifle was $2920 in '96). If you can find one for $2000 and you really want one, go for it.
The choice is yours
