Over several years I have used virtually every brand,configuration,and most weights of LEAD .177 pellets,trying to find a less expensive pellet that performs like these "gold" Gamos. A few were as accurate,but NONE duplicated the Gamo alloys(non lead) for the velocity boost(yes, I used a chrono), or the impact damage on rodents(rats). I used the same 4X scoped rifle. In a fit of anger I killed an adult raccoon(2 head shots) that had been crapping all over my lakeside lot for days! The first shot seemed to stun it, so a second to the head ended his crime spree. Since the raccoon I still use my lead for plinking, but when it's "rat time" I ONLY use the gold Gamos. I just wish I could buy them,at a discount,in bulk. Every claim by Gamo proved true...a real rarity these days!!! Another plus: the shiny "gold" plating makes them easy to spot if you drop any,even in grass.Try finding lead ones in grass!
