CCI Blazer is Aluminum case and non reloadable, CCI blazer brass is brass case and reloadable. Silver Bear is zinc plated steel case,Golden Bear is brass plated steel case and plain old Bear is either lacquer or poly coated steel case depending on which one you run across. All the bear ammo is berdan primed and non-reloadable.

FWIW, most handguns were designed around a brass case. The chamber dimensions and configuration is such that the fairly fluid nature of brass properly seals the chamber on firing and retracts with the drop in pressure. Steel cased ammo in such a chamber is not ideal (not necessarily harmful though). The nature of the steel is such that it cannot obturate (conform to the chamber dimension) enough to get the type of seal the gun was intended to have. The steel cased ammo will leave more soot in the gun (not just because of the dirtier powder).

If you look at the two primary calibers available in steel cased ammo, 7.62 X 54R and 7.62 X 39. Both have significant body tapers. This allow the pressures to act on the body of the case, swell it appropriately and still extract w/o great difficulty.

Cases such as .223/5.56 X 45 and .308/7.62 X 51 are straight bodied by comparison. The intended brass case can swell/seal and spring back to allow proper functioning.

IMHO shoot steel cased ammo in guns designed for steel cased ammo. Stock pile some steel cased ammo for a SHTF situation if you wish. You can put 87 octane gasoline in your LS-6 Corvette, but you will not get the performance you want. You "may" cause damage in the long run.
In life, strive to take the high road....It offers a better field of fire.
