Note, that floating firing pins cannot float, till the hammer is withdrawn from them. For that initial movement it matters none whether the pin float or not. The act of cocking the hammers of course puts some resistance to opening. Beyond that if is in the hinge mechanism there will be resistance in all situations, even with chambers empty & hammers already cocked. As I recall the Rem cocks the ejectors upon closing the gun by pushing in the ejectors via the breech face. If related to the ejectors would seem most likely to be related to the primary extraction or the linkage for setting them & not to ejection itself. This however should be present whether gun has been fired or not. As I recall from back in original post the problem was noted only after firing. Have you tried using a hardwood dowel down the bores to cushion the pins & snapped the gun on empty chambers & see if the problem then exists. If so would "positively for certain" eliminate pin drag. Could be in the cocking mechanism. It is I believe going to simply take a process of elimination to find the quilty culprit. May require removing the ejector mechanism from the forend to clear them etc. I hope you are not simply relating the extra effort required for cocking in relation to opening a cocked gun as "Hard Opening".
