.45 Long Colt target ammo
I have a Taurus Judge that I need to be shooting more. However the only ammunition I have is lead round nose. I've read that shooting such ammo will result in excessive lead buildup and much harder cleaning of the gun. I've not fired the gun that much for that reason (although cleaning after what use it's had wasn't that difficult) and also because of the .45 long colt price. The cheapest I've seen is the stuff I've got: Winchester Super X, 255gr, lead round nose; that I got for $17.00 per box of 20.
Can someone name a better, cheaper round and a source? I have been remiss in not doing all the shooting I should in order to be proficient with this thing. Thanks for any help!
