I happen to believe that your sears model 460 could have been made by marlin.The marlin model 56 should be your sears model 460.
Model 460 is a 20 guage
When they say what is a type of gun is a 460--I'm assuming what they are really asking about is the Wetherby 460 Magnum which is a proprietary belted magnum big/dangerous game rifle cartridge made by Weatherby (the gun manufacturer) for their proprietary hunting rifle of the same calibre.
Yes
460-360bc
100-460
69-73 460 gap is .034" 74 is .054, 75 model gap is .044
100-460 or so
Starting with the 1988 model it did
460 m, or 500 yards. However, the M25 version of the same rifle (sniper version) has a maximum EFFECTIVE range of 900 meters.
IH 460 D refers to an International Harvester 460 Deisel utility tractor. But, buyer beware-- there are full-scale versions of this tractor and miniature models. Get the dimensions!
Possibly the .460 Weatherby Magnum, the .577 T-Rex, or the .700 Nitro Express.
Not sure I have a 440 real and rod and 460 real and rod, still trying to the same answer.
