I'very been soooo impressed by Predator GTO accuracy that I've got to share my experience. I recently bought a semi auto pcp and found these work like a dream. These other two pellets were my top two performers in this particular gun (out of 10 others) but GTO absolutely blew them away.
I shot 10 shot groups, at 25y, in 20-25mph wind with a 1x scope. My expectations were that the Predators would be blown off course. That was obviously not the case and all ten stacked in one hole. I could not believe it, so I investigated.
After some trail and error, I found that one of the biggest reason was the skirts and heads were not getting as bent up from the harder alloy. When I gently hand feed the two softer pellets the accuracy improved, while GTO's stay the same. I also noticed almost NONE of GTO skirts were bent out of the tin.
It too bad the price of Predator GTO is so steep and the weight of the alloy is so light. If they could figure out those two probs, these would be the only pellets I would ever buy.
