Without getting into match ammo and such, what do you feel is the cleanest burning 22 ammo available?
I agree. All 22 ammo is a bit "sooty", but CCI seems the cleanest burning of the readily available "non boutique" ammo.In my experience ...CCI both Standard Velocity and Mini Mags
I happen to have a bunch of the made in Mexico stuff and so far it's ok....I need to try some off brand 22 mag stuff. I have one of the old M-700? H&R 22 mag semiautos I haven't shot in yearsFederal, Remington, CCI.
Stay as far-away as possible from anything made from bat-guano in Mexico (Aquila) or from Eastern Europe (graphite).
Yes - however copper plated 22's in standard velocity CCI isn't available (at least AFAIK). They are available in the high velocity Mini-Mag's but the standard velocity will give you much better accuracy out of most target pistols. To me, accuracy trumps ease of cleaning and I have never had any issues cleaning after shooting standard velocity lead ammo.CCI Mini-Mag is my first choice.
Copper plated is significantly better than Lead.
