If anyone is adding metal shavings to fieldpaint, this should be treated as assault. Paintballs are 3 to 3.8 grams by design for safety.

The military did conduct studies adding bismuth. It is nearly as heavy as lead but much lower toxicity. Its the stuff in pepto bismol.

The US Army goal was to improve:
- weight (4, 6, and 8 grams)
- range (up to 100 meters)
- dispersion
- force WITHIN less-lethal

More important factors than ball weight, were:
- Gas seal behind the paintball
- Fill mass symmetry

Injecting bismuth caused it to shift during launch and spin wildly off course. RIFLING of the barrel did not compensate for the mass assymetry. Paintballs which exhibit mass displacement swerved immediately after leaving the barrel.

Goes without repeating that OVERboring caused gas leak and balls "rolling" out of barrel with poor velocity.

6g and 8g shots still performed poorly beyond 30m or when velocity was below 220fps. The goal of these studies to reach 45, 60, 75 and 100m could not be achieved.

Also under 15mps (50fps) velocity, balls did not break.

We will do horrible unspeakable things to you in Canada. We will mend your body for free, stuff you full of bacon and frequently apologize for things that are entirely not our fault.

And pour REAL maple syrup all over you. Don't ask why

O.o

P.S. What field is this (in Canada) ?

In Topic: Most accurate barrel?

Once you determine a mean point of impact, accuracy is math. Vikhr graph and the top and bottom edges of circles are confusing what really matters: grouping.

Math gives me headaches, but Mann's originals help visualize mathematical circles where most paint lands. Or print it and grab a ruler.

Mann's Examples (top to bottom):
Xball gold + Aluminum freak 0.682"
Marballizer + Aluminum freak 0.693"
Xball gold + Hammerhead 0.688"
Recsport + Stainless Steel freak 0.689"

Ballistics apply: yes and no

INTERNAL ballistics:
Paintball is technically not a solid object. Friction and therefore polish of the barrel are important. Technically gelatin becomes solution above 34 celcius (sweatty balls) and loses ability to flex below 4 celcius (cold ball breaks). You want a gentle grip on your balls, not too tight. Pun intended.

EXTERNAL ballistics:
When the ball leaves the barrel. Gravity, windage, drag, etc all apply except traditional equations do not perform well below 350fps.

TERMINAL ballistics: what the paintball does when Dangermanxx shoots himself in the foot :D
