Sheridan/PMI P12 Performance

O'Lane · 02-26-2008, 05:40 PM

Hey guys,

I just aquired a P12 in a trade, the marker is in good condition, etc. But it seems to have some velocity issues. I'm using Crossman 12 grams, it gets about 5-10 good shots ranging from 280-300, but then it just starts lobing the paintballs, many of the shots fall to the ground 50' from the muzzle. I don't know if the it is the 12 grams, but the temperature is around the mid to upper 20's, so it could be the cold. Has anyone had this problem? Other than that, what are some good ways the increase the performance on the P12? I'm already planning on putting a cocker frame on it and have a RVA installed on it as well. Thanks.

if you can get 280-300 now in 20 degree weather with 12ies, it's a keeper!

20 celcious or Ferenheit?

If it's 20 F ... then it is waaaaay to cold for CO2 cartridges to work well.

20 C is 68F... so it should be too cold....

Anyways... if it's below freezing outside then it's too cold for 12 grams.

Yeah, it's around 20*F, so it may be alittle to cold. Would the cold explain the rapid decrease in velocity after several shots though, wouldn't all the shots be low velocity? Thanks for the help so far guys.

You should feel lucky to get it to shoot at all. I tired to play with a phantom in snow when I was a super noob (probably still am) and I just got my phantom. That thing wouldn't shoot period.

My PMI-1 gets ten good shots on a 12gram on a warm, sunny day. You should be grateful!

it's going to be a keeper, get an RVA for when it's 80 and it makes drywall explode! You'll have to turn it down if it shoots 280+ at 20F!!

O'Lane · 02-27-2008, 10:45 PM

Yeah, I figured it is shooting hot, out of curiosity, what do you guys think, should I set it up for CA or leave it as a 12 gram powered marker?

Stuffy · 02-28-2008, 06:45 PM

I say leave it, but if you do want CA use a drop in CA adapter from palmers, so if you ever feel the need to go back to 12grams you always can.
