I don't recall if the 66 had the floating chamber or not but it may well have. But I do know that the Remington 550-1 that was built for quite some time following WW2 was the first to have it. It was the last of the 'Walnut and steel" Remington semi-autos before the start of the potmetal and plastics era and was probably too expensive to continue to produce. Therefore the Nylon 66 and the model 552.jimsong said:Somebody refresh my feeble memory, is it the Nylon 66, that has the so called "floating" chamber? There was only one rifle that had it, as I recall, and I think it was the 66.
The "floating" chamber allowed the use of any rimfire .22 to be used interchangably.
You could load the magazine with shorts, longs, or long rifles in any order, and the rifle would just eat them up.
Bear in mind that Remington had 'firsties' on that design producing the Models 24 & 241 before surrendering the rights that Browning then assumed.oldsparkey said:The next one I get will be the little Browning 22 semi-auto , it breaks down ( the barrel and forearm can be detached ) from the stock and receiver for transport. One slick shooting 22 with bottom ejection....IE: Scope on the top.Chuck.
