Seriously though, I use 4.51 pellets in cold weather and 4.53’s in hot conditions (zero, trajectory & power check regularly also) With thinner barrels like S400’s I didn’t find such sensitivity but thicker barrels like the Mpr I’d noticed larger pellets flying slower and dropping qu...

Stop the world, I want to get off?

At least that’s the direction it’s heading
