floorplate not going back on?

[03mossy]

i have an older weatherby (1954 FN action), the floorplate will not click back into place. nothing appears to be bent but it will not go back on. this is not a hinged type, it comes completly off. any ideas?

are you sure the box magazine is in properly?  I know in a lot of rifles that the box magazine can sometimes be put in slightly wrong, but looks okay and prohibits the floorplate from being able to correctly be secured.
