Thanks for that. It was just a thought because I was looking at the weather link on the Worlds website and started internalising.
I might just load two pellets into the gun for the long ones then. Wink

I did a quick search and i found it will effect your shot.

Barometric pressure can definitely have a significant effect on the accuracy of your shot because it affects the density of the air, and therefore, the amount of resistance it exerts on the pellet as it travels to the target. also The higher humidity - higher point of impact as well.

Does this effect a springer more than pcp, or vice versa?


Thats a tricky question. I would say it would effect the Springer more than a PCP. The PCP has its air tank compressed to 3000PSI and your regulator will control the amount that goes into the shot. So when you fire the gun it will same power behind the pellet each time.

A springer uses the air around it to compress to takes it shot. so when the air changes your power will go up and down with the changes around you.

You would need to sit down and work out how much it would effect it or download a ballistics program to do it for you. But if you are shooting in a FT event you cant use anything to measure it anyway. just adjust on the fly if your shots start hitting high or low :)  and always zero before your shoot.

Anyone know the short answer to this?
Without getting to technical I wanted to know how much change it would make if we were shooting on a day with a high pressure system over us as opposed to a low pressure system. For example if we were shooting at a target 50m away using the same turret settings would the the POI change from the high pressure to low, and approx how much?

Does this effect a springer more than pcp, or vice versa?

Thanks
