Last summer Dale sent me some pellets to test.
My rifle is an unmodified Benjamin Marauder PCP, with Athlon, Talos BTR 4-14x44 scope mounted.
When the pellets arrived, the air quality here was so bad due to forest fires, I was to much of a weenie to go outside, pump the rifle up and shoot it.
For Christmas I got a air tank, and this weekend the temps were a relatively balmy mid 30s above zero, with about 6 inches of slushy wet snow to wade through, I did some shooting at 40 meters.
This is a control group fired with store bought JSB EXACT KING 25.39 grain pellets.
