Another Part of consistency is your refresh rate. A regulator will help this. So when your shooting a few balls a second, they can hit right on top of each other instead of making a spread. Of course, velocity and acceleration has a lot to do with that too. Even air speed and how many dust particles the paint has to hit before it reaches its target, but those variables are small and almost unnoticeable.
How to Snipe
So now you know the limitations of your marker. I've told you how to counter liquid CO2 and how you can make your gun shoot more accurately, and everything in between. Now you can apply it into the game, but just having a marker that can shoot the wings off a fly in midair isn't going to help you at all. You need camouflage, and you need to use your head before you can actually "snipe" (shudder).
Camouflage
The best camouflage depends on where you will be. If your in the desert, get desert camouflage. If your in a woodland environment, get woodland camouflage.
There are many of different kinds of camouflage out there. I did a study on 5 of the most common types used by the military, and I've found that MARPAT, the new Marine Corps camouflage is the best. In woodland and desert situations. Tiger stripe is the next best.
I won't go into detail, but MARPAT is good for concealing both movement and stationary objects, and Tiger stripe is good for concealing movement.
I see a lot of people with ghillie suits and stuff too.. Most of the time they bought them on the internet, which doesn't work. You need to make your own ghillie suit in accordance to your surroundings. Use local shrubs and vegetation to adorn your ghillie suit, not strips of burlap and fake leaves form the kit you bought.
Someone here also said something about ghillie suits being almost like cheating. A paintball isn't going to break when it hits two feet of burlap.
Go to a local military surplus store and talk to the owner and tell them you need something good for paintball and they can hook you up with a GOOD ghillie kit (remember to add your own stuff) or a good pattern of camouflage.
You can't buy real USMC MARPAT unless you join the Corps. Or you buy it from ebay. If you have a friend in the Corps, ask him or her to go to the local base's commissary and hook you up with some REAL MARPAT. The stuff is great.
I've painted a lot of my stuff. I got 4 kinds of paint form a hobby store and spray painted my mask, and my hopper. They look very cool, and work very well. When I tested it out in the game, I noticed that could stick my head sound bunkers a bit and people wouldn't shoot at me as much. Either they couldn't see me or were new players.
I forget which colors I got because I ripped the labels off the spray cans. I think its Olive Drab, Field Green, Medium Green, Tan, Earth Brown, and Black. Use a base of Olive drab on everything, or spray it first with the olive then let it dry and apply the other colors. I did it more in stripes. Experiment on some cardboard like I did before you do any damage, and take some fine grade sandpaper and sand anything plastic before you paint. I was watching a commercial about some paint that sticks to plastics at a molecular level. Its sold at wal-mart, try it out and tell me how it worked! EDIT: Its called Krylon Fusion. Not much color availability though.
How to Snipe
Don't shoot at someone just because you can see them. chances are, if you can see them, they can see you, but if your wearing your new MARPAT, you should be fine. Don't shoot and give off your 20. (10-20 = location. Its like saying 10-4 )
Take careful shots, and analyze everything that is going on, but don't get tunnel vision. Always check behind you and to your sides and look at bunkers CAREFULLY to see if there is any signs of movement.
When you need to move, you can move slowly if there is enough cover, or you can haul ass. They might see you, but if they saw you when you were moving slowly, they could hit you more easily. If your going to change bunkers because your taking fire, don't wait all day, run your ass off.
Don't let someone take advantage of your one-sided bunker. If someone comes up from your left and there's someone in front of you shooting at you, your cornered. Always be aware of your surroundings.
For more tactics, look in the recball forum of [PBF] for a thread entitled ' woodsball tips/tactics'. There is a great sticky in there.
The position of sniping.
I don't snipe at all, but I like to be as accurate as possible when taking my shots. Your body position and how you hold your gun has a lot to do with this. Laying prone on the ground is very stable, but limits your maneuverability, makes you easier to see because the bunkers are usually designed for you to crouch.
Keep the gun tight in your hands, and hold it as close to you as possible, or if you have a butt plate or stock, use the fore grip to dig it into your shoulder. Get on one knee so if you need to haul, you are already halfway there. This is comfortable for me, but a lot of people might have discomfort staying like that for a long time. But if you're a good 'sniper' you'd move around a lot. Keep your elbows pinned to your sides. Try to make the contacts between your arms and the gun as firm as possible without breaking the gun/straining yourself and keep your elbows as tight as you can.
If you have something like a flatline barrel or a pro-lite or pro-carbine, you can hold the hand guard, which is a very nice thing. Its one of the best ways to steady a firearm, but if you'd notice, a lot of newer military guns (MP5k PDW, And the numerous add-ons for a Colt M16 or M4 series rifle) have fore grips. Fore grips are the best way to go. There ya go Mr. 1337 sniper.
The Sniping Marker
The sniping marker can be almost anything that will give you consistency, reliability, accuracy, and speed (if you need it) all in the same package. For this I suggest a spyder if your going low-end. They can be easily upgraded, but don't be fooled, these markers won't amount to much when up against other marks. Sure its the skill of the player and not the marker, but the marker is a tool, and how efficient that tool is can be the difference between winning and losing.
If you're going high-end, get an autococker. Fast, reliable, and they get the job done. Some can be as cheap as 400 bucks. Some can go for up to a thousand bucks. They really are great markers. You can get all sorts of great upgrades that will further improve your marker. If you get something like a Karnivore, you don't even need upgrades. It rips on its own.
If you want to go pump, look at a Sniper II. Its the autococker in a pump version. Great solid marker. I've seen some really nice phantoms out there too, but if your going pump, you better be ready for a challenge. Most people are using semis nowadays, and a semi can put our 10+ more balls at you then you could get out in half that time. If you want to feel more secure during reloads or when your focusing on something else, look for a backup marker. You can get a Zeus, Delta 68, or Pt Extreme for under 120 bucks all set to go. I've heard that earlier models of each of those guns has its flaws, so be warned.
CAMOUFLAGE! Get yourself some good camo for your gun. Camouflage tape, or even paint will do the trick. I left my marker red because I like a challenge, and because I think camo looks retarded for speedball... I don't really know why I stopped.. But I did. I have a camo hopper (200 round gravity-fed) and a camo mask. Tape up hoses and fittings, and things that go clank. Remember to pre-sand when painting stuff, or if your painting plastic, use that Krylon plastic paint I mentioned before.
Scopes
Paintballs aren't accurate. They are turbulent. You know how they work. If your aiming your 48x scope at someone's head, chances are your going to hit the tree next to them or something. Just because your scope is on it, doesn't mean your going to hit it, especially with CO2.
Red dot scopes are okay for close range, as long as they're well calibrated. I've never used a paintball scope, but I know real scopes need to be calibrated every so often. I'd assume in paintball where your running and jumping and bumping into things, the scope would get ll out of whack.
If you want to see what's going on way down the field, get a monocular. They're less bulky then binoculars, and way more compact. Perfect for paintball. Just make sure tis a wide lens so you can see through your mask.
The lowdown
You can't snipe people from a million miles away. You can, however, snipe them from a concealed location, by shooting smart, and having the equipment to do so. With one hopper, you can take out 4 or 5 people instead of wasting away pod after pod after dollar of paint. Be a smart player, and don't be cocky off the field. Remember that paintball is a game, and be safe. Always wear your mask and don't shoot or shoot anywhere near anyone who isn't wearing a mask.
Calling yourself a sniper is just going to make experienced paintballers laugh at you. Tell them you like to play back, but don't like to spray too much paint or make too much noise. To a speedball, the woods is an uninviting place. I'm a speedball myself, but I have learned to love all aspects of paintball. Don't be like everyone else. Paintball is a sport, don't let woodsball and speedball break apart. IF your a newbie, don't be cocky. Don't very say or do anything that will make paintball look bad.
