Hi guys! I was wondering if it was possible to adjust the air valve on an air pistol revolver. My Ace-in-the-Hole has been generally shooting 1" below the target, but temperatures have been rising with Spring coming. I shot a bit last week around 15 Celcius and it was shooting 2 to 3 inches higher than the target.

Does anyone know if there's a way to adjust the air output to make sure I always get the same average speed coming out?

Or is my best bet to shoot heavier pellets in warmer weather? I've been shooting Crossman Wadcutters whih weigh at around 7 to 7.4 grain I think. Would shooting 10 grain (or more?) in warm weather help to lower the speed and maintain average performance and accuracy?

Thanks for your help!

15 C is still quite a bit below the 68 F that these guns are balanced for.

Personally, I wouldn't want to tear into one of these. Anything done with the porting is going to be kinda difficult to reverse.
I would suggest a uniform pellet like the JSB 8.44 gr dome before going to something heavier. A heavier pellet will have a steeper trajectory, and likely land even higher on the bull. Easiest thing to do is move back. Given the relatively low velocity mine shows, it probably won't be that far for an inch correction- likely 7 or 8 feet...
