Another option is avisit to the local Scrap yard and tear a few CV joints apart, you could also take a look at Joerg Spave's youtubs channel for some wacky ideas for Catty ammo http://www.youtube.com/channel/UCVZlxkKqlvVqzRJXhAGq42Q This guy's a nutter, but funny with itunsure wrote:ive said it before , if you can get friendly with your local garage .when they change out a wheel bearing there will be around 16 to 20 good weight ball bearings that would normally end up in the bin . worth asking if they`ll keep them for you .
ive collected around 150 in less than two weeks , just from what was scattered around the bench .
As for Me in a WROL SHTF type situation I'd probably favour a ruger 10 22, fantastic little Rifle, easy to maintain, and with the Airo conversion barrel chambering 22lr nitro blanks, an added string to the bow, thats as cheap as chips to run.
Other than that in reality, my weapons of choice are my trusty Theoben Sirocco Classic 22, my Hoyt Compound Bow & XBow.....well, untill my Horton Fury arrives wooohoo
no need for Cartridges or reloading gear, Arrows Bolts and Strings can be made.
