Things I liked:These are shaped and formed very well and the copper coating allows them to work in guns that I could not get even high quality lead balls to work in. Things I would have changed:Well, I would like to get them cheaper and I would have them of a more uniform size. These ranged from .1735" to .177". Unless you sort them you are not going to be able to use them in some guns mentioned below. What others should know:I am old school. Heavier projectiles are better than lightweights as long as you don't take it too far. I had tried non-coated lead balls from H&N in my Colt 1911 Special Combat, Crosman C-31 and Daisy Model 25 and all of them had jams. However, with these I was able to get all three guns to function perfectly --- as long as I sorted the copper-coated lead BB's into the following categories: .1735" to .175"; .175+" to .176" and .176+" up. The Colt and the Crosman C-31 will function only with the smallest sizes up to the maximum .175". The Daisy 25 also was most consistent with these smallest sizes, but still functioned with shot up to .176" but the Chronograph dropped when one of the .176" balls were encountered, so I would say it best to also limit the Daisy to the smallest sized of less than .176". The .176" and above were great in my Crosman 1077 and Crosman 2100 with very impressive accuracy. The bottom line is sorting these is a pain and they are too expensive compared to other ammo offerings that will work in these guns, unless you are a nut like me that just wants something better for some special purpose he may find for them in the future.
