22 Predators vs 25 Predators

I have now had the chance to do accuracy testing with new Predator pellets in both 22 cal and 25 cal, 12″ and 24″ LW barrels. The 25 cal barrels/Predator do very well but not the 22 caliber Predators. All of my accuracy testing is done from a locked gun vise that give me some incredible groups with other pellets.

Anyone else noticed this? I did a search and someone else mentioned it on the Yellow forum. I am wondering if it is the LW choke design. I see some decent groups with the 22 Marauder on other forums.
