Higher "safe" velocity for 50 cal

Has anybody tried setting a higher velocity limit for 50 cal? I don't know what formula is used to determine what a "safe" velocity is, but if it depends on energy or momentum, 50 cal should be shot at a higher velocity, which could help increase popularity by offsetting its disadvantage of higher drag per unit mass.

ASTM standards say 300 fps maximum for any caliber size. In Europe and possibly other places, they use energy ratings, so in those places 50 cal can be shot at higher velocities than their 68 cal cousins.

The games we run with 50 cal, we actually turn them down lower than our 68 cal rentals, but then we are running "Low Impact" paintball games with 50 cal.

Is 50 cal any more popular in Europe than it is in the States? If not, that debunks my theory.

Though 50 cal does fill a niche by your example. If it were more common and cheaper, maybe more kids would get involved in paintball.

I believe I read somewhere that in the UK they can shoot 50 cal at 325 fps while 68 cal is limited to 280fps or maybe it was Australia....
As horizon said, most field owners are offering it as a "low impact game". We have had good luck with testing paint at velocities as high as 350fps and still have a decent shot without to much distortion, but it definitely works better sub 300 fps.
50 caliber in the UK is very popular, especially compared to here in the states.

Not sure, but I bet there are some people who live in Europe on PBN that might be able to answer that for you.

It's hugely popular with the 10 to 13-14 year old crowd. Also hugely popular with their parents.

I agree. I feel Splatmaster, although it may have it's place, is too low to be considered part of our "extreme" sport of paintball. We chrono our rentals between 250 and 260 fps for our Low Impact 50 caliber paintball. That decreases the energy substantially compared to 68 caliber but it's still paintball. I made a small chart on our website for my customers to make a comparison. http://tntpaintball.com/the-physics/

Great chart. I just showed my 9 year old and I think I am going to get her out this year. A field by me is starting low impact .50 games.

We used to mess around playing outlaw ball with .50 cal when they first came out. We would normally chrono at 350 with no issue.

That's awesome to hear Crazy! I am assuming it is HSI you are talking about and I was happy when I saw that they added low impact .50. I'll never play it myself, but the field will make more money which means they will be open for us .68 caliber players longer!

FWIW, I've been shot with a 50cal round at about 325. Had a Spyder on CO2 go kind of hot, and couldn't get it below 295 regardless. Very noticeable sting and welt left behind, actually a little worse than 68cal. We were doing a golf outing using a human target (me) as a charity shoot at one of the golf holes. This year, I switched out to my Resurrection set to 265.

We set ours at about 250 for our rental games and try to get relatively brittle paintballs.

during the latter part of last season we started running 50 caliber paintball games and were marketing them as low impact.
when we run the games as a low impact we try and run the velocities between 140 and 160.
this worked well if the group was very young players.
once we start getting players better closer to the 10 to 12 years old age and they still want to participate with 50 caliber low impact games we bump up the velocities slightly so that the ball has a little bit more zing and right around 200 feet per second is where we kind of trying to gauge it.
that way some of the borderline teenagers still get a low impact experience but they don't get whiney if the velocity is lower for the really young kids.
they all still go home with big smiles on their faces.
My to cents

Hypotetically, if you chronoed a .50 at say.... 325 fps, would it have close to the same performance as .68 at 280?

Pfft, no form of paintball counts as an extreme sport. That's pure marketing BS and promoting paintball as an extreme sport has probably done more harm than good. Unless you're talking about skydiving paintball or something.

merked, technically speaking .50 cal doesn't start to match the range etc. of 68 until you're getting up around 450 fps. The problem is that at that velocity the smaller surface area = greater pain even if the overall energy is the same. Not to mention that getting the ball to that speed is tricky.

I'd like to see a shaped .50 round for milsim.

Why .50? Fields charge same price for .50 and .68. I rather have .68 where I can guarantee breaks. I tried .50 and even when the player knew it bounced off his mask, he said he never got hit.

Honor system doesn't work in paintball. .68 would have rendered his vision useless with a few mask breaks.

Simple, innit?
