I use Remington #10s on my old armies, I never have to hit them twice and they stay on well too. I shoot a reduced load of 30gr 3f with veg. fibre .030 wad and use CleanShot almost exclusively these days. Cowboy range accuracy is right on, plenty of smoke and clean up is a breeze. These are the new stainless 5 1/2 inch models. I use RWS 10.75 caps on my older 7 1/2 ones.
