I got mine for my birthday in 1968, and in that era you could give them 25 pumps. I bought a replacement a few years ago, and the lit states 10 pumps. I haven't tested beyond five, because three is enough for a squirrel or sparrow on the planter or railing.
I got my 760 about the same time, and I'm a little ashamed of all I did with it back then.. No grizzly bears but I figured out pretty quick that you could turn it into a scattergun.. I didn't have anybody to take me in hand much back then.. I met the 10 pump limit with never less than 14 pumps.. Once I wore it out a little, I took to doing the BB Shot thing. My first reality check was a rabbit that I "knocked down" (with 13 BBs). It didn't die cleanly and it took me forever to finally make it stop suffering.. It hurt me, and began to wise my very young hind-end up about shooting living things..
(God made a better Daddy to me than daddy did, but that was among my first experiences with that at the time..)
I don't want to do the Crossman thing, but I swear!! I put a GA tag on the car and they wanted $1,000 Bucks!! They let you finance half of it over a year! They
know it's too much to be charging somebody for a tag!! The Acquisitions Dept has been under alot of strain since Santa Claws started bumming smokes last fall!
So far, homework has taken me to consider maybe a RWS underlever, but GOOD GRAVY folks! I could buy a GLOCK and a couple of extra magazines for that!!!
Is there any problem with putting a cheapie little $50 red/green dot on something like that? I've got a "extra?" 3x Sig sight around here somewhere. Does an optic have to be some special ju-ju kinda thing? Surely not, right?! (I know. Don't call me Shirley..)
