Premature Ejaculation Problem

[BoyntonStu]

I muzzle load a tight fitting projectile.

When I pressurize the chamber, air gets to the barrel before the piston seals and the projectile prematurely ejaculates slowly out of the barrel.

I use a piece of soft PEX tubing as the ramrod.

I thought of tying a cord to the PEX that could be used to retain the projectile during pressurizing.

Once pressurized, I could loop the cord over a fixed point to retract it safely from the barrel.

I would never muzzle load a 500 psi cannon.

Other than building a breech loading port, is there a better solution?

I've heard that there are some pills and therapy available that help fix that problem, but I wouldnt know.  Just kidding, one thing that may help is to slowly fill at first, giving enough pressure to seat the valve, but not enough to move the projectile. Once the valve is seated, you can open the throttle. If you are using a dart which has practically no friction, this solution will not work. Another thing you can do is make the rear o-ring completely air tight. Pressurize the pilot, then pressurize the chamber from your schrader valve you have to bleed the airgun without firing it. This may boost your performance a tad as well.
