Pistol Size crossbows?
RON L here = SERESURPLUS
I have had a bunch of these over the years in the 35 and 75 pound bow range! They were a fun diversion and I guess with a lot of use and pratice, you might be able to take small game, I.E> rabbit, squirrl and the like, but most crossbows are severly underpowered! The rifle types I've had in compound as well as conventional bows up to 200 pound range and due to the "Bum" type of start the crossbow bolt get, it's like division of that power by more than 3X! Most are not enough to hunt with and most states don't allow for legal hunting with a crossbow of any kind? Ohio is the olny state I'm aware of that allows normal hunting with them!
I'm not trying to shatter your well though idea's, but they just are short of the task! With that said, they are fun, serve a purpose of target and fun shooting with minimal backstops! Bolts (Arrows for the crossbow) can be found in the pages of a shotgun news magazine and most walmart stores carry them! They are legal to buy through the mail and they can range from crappy ones about $12.00 for 10 to aluminum jobs costring 5X that! Buy what you like and can affoard! Best to buy a few different ones and see what works best in yours?
Good luck, have fun and let us know how that all works out, OK?
