A friend of mine told me about a neighbor who has about 15-20
full boxes of factory Peters 45 Colt ammo he wants to sell.
These are the old red,blue,cream boxes. I have a few
revolvers chambered for 45 Long Colt, I know nothing about
45 Colt ammo. Is this caliber ammo suitable for use in my
S&W revolvers.

Even though the price is suppose to be very good I don't want
to take a chance if it's going to damage my revolvers.
