I purchased some of the Gamebore EVO 2 1/2" shells last summer. 1220 FPS, they were pretty "HOT" to say the least. In fact I had to give up shooting them that day because the pressure was so much I couldn't open the gun after shooting the first shot at each station.
They were felt wads, not sure if that had any effect on the way they performed.
Shot one box, sold the other nine boxes.
The Gamebore Evo 21g 12 bore loads are very considerably 'hotter' than the equivalent Hull Cartridge CompX 21g cartridge. I much prefer the Hull Cartridge product.
