I’ve noticed that my Maverick PCP shoots the first shot 10-15 fps faster than the rest. What could be reasons for this? Leak in 2nd reg? Cold barrel reducing leakage?
Just curious why this might occur….

You say cold barrel. Have you ever reached out and wrapped a hand around the mod after 10 shots? Cold barrel might be true but just the opposite of 1st shot cause thats the warmest it gets

Although it could be a slight contraction causing more drag especially if he’s shooting a slug that already is fairly tight

I shoot pellets, usually light ones. Really just looking for ideas. Nervoustrig’s sounds best so far.

Too much hammer spring. You should be able to play the balancing act and get that first shot to be in the 5-7fps range. Be it 5-7 too fast or too slow, doesn’t matter. You’re good to go. Then just enjoy shooting and don’t fuss over the chronograph.

How many air guns have you seen with a warm barrel after a few shots(or many). Except for ambient temperature of course. The hpa always has a cooling effect as it rushes out of the barrel.
Firearms are a different story as they can heat up rather rapidly as the powder burns.

Thanks for the explanation! I recently replaced the reg o rings so this makes sense. Thanks!

Thanks for the reply! Makes sense! I was assuming that heat would be generated from lead on steel or “sticky” valves and didn’t consider the cooling of hpa being released.
