Best price I've seen in 2 years and first Winchesters I've heard about in that time. I just paid $75/1K online and paid hazmat on top of it.
I want to get more LPP and prices and availability are not that good. $80 and up if you can find them.
I welded some tubing to make my first folding gun cart. Later I bought a wooden cart for $25. Next up was a $20 baby jogger I adapted. Recently bought a Rugged Gear cart for $60 and added my ammo tray from my jogger. A handful of carts were available within the last month with varying prices. There are options.
Whatever you do leather wise, do not buy cheap leather brand new. It will not hold its shape and you'll end up spending money again. I bought a used Kirkpatrick rig 20 years ago for $150 that is still in good shape.
