Paintball to bore matching

This is a very common statement made to players to improve accuracy. Most will give you a confused look. So here's simplified explanation.

Take the paintball and place it in your barrel. Try blowing it out like a dart gun.
If it just rolls out of the barrel, barrel bore is too big. If you can't just blow it out, the bore is too small. What you want is to be able to blow it out with just your mouth fairly easily.

When the bore is too big, there are turbulence issues. As well as putting a lot reliance on the marker's detents. Obviously if the bore it way too small, the paint will get stuck. If it's just slightly small, the friction against the barrel could cause spin - therefore, inaccuracy. So you are looking for the bore that you can blow out with your mouth with a descent force.

Those that don't have a barrel kit will need to find the paint that best matches and use that one. I find more player just need to find the right paint to bring with them. If you have to use various paint (i.e. any variation of field paint), then maybe you need to get the barrel kit so you can get the best accuracy from what you get.

Depending on what your situation, you should act accordingly. If you happen to be able to bring your own paint, find the best match. If you don't want to buy a case or 1/2 case, try ansgear.com. They will sell any paint they have in 100 round batches. That way you can order the paint you can get a hold of to find your best match. Though personally, the RPS Marballizers are readily available and one of the best paintballs you can buy.
