You need to find more information about the firearm. Winchester made 25 different models of the "94" and they were not shotguns. Models like the 9410 were. Contact winchesterguns.com for some answers. * Ignore the first answer. A 16 gauge Model 94 is a Stevens/Savage shotgun.
I don't know what ``hull injection'' is, but a Savage 311 schematic, in PDF form, is available for 99 cents from Numerich Arms. I'm still looking for a freebie myself. The cheap one is here: http://www.e-gunparts.com/product.asp?chrProductSKU=PDF0445A Hope it helps. Nels
Double-check that model designation, Stevens did not make a 'Model C.' They made a 94C, 311 Series C, etc, etc. Please list all the markings on the gun exactly as they are on the gun. firstname.lastname@example.org
