Like a bunch of other folks, I am worried about ammo availability in the near future. I also worry that ammo components might be difficult to get. I've handloaded for years and recently set up to cast bullets in quantity. I have a pair of Lee 6 cavity moulds in each of the various calibers I shoot regularly (cast in tandem), and set up a Star to lube the bullets. I have the Lee 125 grain RN for the 9mm.
The 9mm is easy and cheap to load. I get decent accuracy from my Barsto barreled Glocks using cast bullets and Unique. Using my own bullets, I can make ammo for 5-6 cents per round.
I bought a Colt 9mm carbine with the idea of using the cheaper ammo for close range practice. The 9mm AR carbines are straight blowback and don't have a gas system to get fouled up. Has anyone successfully run 9mm cast bullets in a Colt 9mm carbine? It should work, but I'm concerned the 1/10" twist barrel might be a bit fast for good results.
Experience, advice and suggestions would be appreciated.
