Zeroing an M16 rifle at 25 meters. Why?
208463
25 meters is used to zero a rifle because the trajectory of the bullet will strike the same place at 250 meters.\n\nBy using this technique you will be able to hit any target out to 300 meters without having to compensate for the drop of the round.

it must be the drug'nov svd sniper rifle.......take a look at the link below, it is an older version issue.

Firing the weapon vertically...\n\nV^2 = Vo^2 + 2gh\n0 = 600^2 + 2(-9.81)h\nh = 18.348 km ; where h is the maximum height reached by the bullet\n\nThe work done by firing this bullet to reach the max height is...\n\nW = mgh\nW = (5 gf) (9.81 m/s^2) (18.348 km)\n\nBTW, 5 gf? What the fcuk is that? I'll just assume this as 5 grams.\n\nW = 900 N-m or Joules\n\nPower is the rate of doing work. Power therefore is equal to...\n\nP = W x bullets fired per min.\nP = 900 x 250 bullets / 60 secs\nPower = 3,750 Joules per sec or watts.

Bound's hubby here:\n\nThe AR-15 Service Rifle is available in two configurations: rifle (20 in+ barrel) or carbine (under 20 in barrel). The carbine may have a collapsible stock. As a rule of thumb, the longer the barrel, the more accurate the rifle. Both are chambered for the .223 Remington round so the amount of damage either rifle causes will be comparible. Look at NRA Service Rifle competition and CMP matches (President's 100 and National Trophy Matches) and the competitors on all of these events use the rifle version with fast twist barrels (1:7 or 1:8) to stabilize the heavier bullets at longer ranges (600  yards). \n\nWhat you buy should be determined by your intended use for the rifle. Buy the rifle and add $400 worth of parts and you have a rifle competitive with any other match rifle. A chrome lined barrel will not affect match accuracy. My AR has a Colt chrome lined 1:7 barrel and I can shoot in the high 90% averages with it. \n\nI suggest you go with the rifle which gives you more flexibility and more legitimate use. \n\nGood luck.

i use CB caps for what you are doing.  it's a regular long rifle case with just primer and a smaller bullet.  CCI makes them, and i bought a brick from cabelas.  it shoots a 20 grain bullet at about 900 fps, no noise either.  i can hear the hammer fall.

Please don't buy it. 32 Degrees markers are basically Spyder clones. You are better off with a Tippman or Spyder.

I searched this because I was curious and a terminal velocity would be variable according to range and wind conditions but leaving the muzzle of the gun,  a muzzle velocity of 1610m/s (5,281fps) which means you certainly wouldn't hear it coming at over six times the speed of sound\nhttp://www.army-technology.com/projects/stormer30/index.html\na site you may find of interest.

First I Invite you to join the swedish Mauser Yahoo group. Next If you have never used open sights, heres the $.02 lesson. Sight the bullseye (plate) to sit directly above the front sight ( without the gap)\n\n                                 O\n                                  II\n\n\nThe rear notch is alined like this:\n                                     \n                              &#92;||/\n\nSo when you shoot, focus the eye on the front sight thus making the bullseye fuzzy and all aligned like this:( but no gap!) Adjust your hold till the rounds hit the black\n\n\n\n                                O\n                               &#92;||/

You can look at the ballistics statistics or go to the manufacturer. it also depends on what distance you are wanting too look at.

Have you ever picked up a loaded AK-47 magazine and a loaded m16/m4/AR15 .223 magazine.  The difference is noticeable.  \n\n1- 7.62x39 ammo is heavier than the 5.56x54.\n2- The m16/m4 is a much more lighter rifle.\n3- The 5.56 fires at a higher velocity than the 7.62 (almost double) thus getting a flatter arc, better for longer range shots.\n4- The m16's magazines are MUCH more convenient that a AK's magazine.  I MilSim airsoft and the #1 problem a AK-47 user will have is the magazine size.\n5- The AR-15 is a domestic gun, the AK-47 is foreign.\n6- A .223 (5.56) will penetrate body Armour better than a .308(7.62).\n7- Many people say the 7.62 has much more stopping power than the 5.56.  And that the 5.56 has a problem of over penetration.  The solution is Hollow Point bullets, although they are "Illegal" to use in war, I believe they should be legalized for our troops in Iraq, for we are not fighting a regular army, they are combatants without a country, criminals.\n\nP.S. I actualy held a Romanian Ak-47 (semi) today, Just reminds me of why terrorists can't hit anything, the sights SUCK!

Hey, Great job! For a 13 year old, 330 meters even with a scope is good. Even for someone who has been hunting for a long time, iron sights at 330 meters/yards to kill a deer with a .243 would be very hard to do. So good shot kid. Have fun hunting and by the way how big was the buck?

Bound's hubby here: \n\nWhen I purchased my M1A, I also purchased the SA 6x40 Government Model scope. I like the rangefinding / distance compensating recticle. I generally use my M1A in competition, using iron sights only, so I have not shot this scope much. \n\nI find it is a quality scope. The one draw back, is that the range compensating recticle is calibrated using 168 grain Match loads (equivalent to Military Match M852). I prefer the heavier 173/175 grain Match loads (M118/M118LR) ... but for government work, the scope will put these rounds close enough to where I need to place them. \n\nI would not rely on the range compesating recticle for long range precision though. That recticle will place the bullet on target, but not with pin-point precision! It is better to have a target quality scope and shoot it to establish zeroes at the distances you plan to shoot. \n\nGood luck!

Actually, spartanerik, the XM8 program was cancelled. The M4A1 is a good rifle, but I like the M16A4 better. It has a little more power and accuracy than the carbine, and makes for a pretty good sniper's weapon, in a pinch. (With optics, of course)

depends on the degree of accuracy\n\nto the nearest 1 m it would be \n\ngreater than or equal to 159.5 and less than 160.5\n\nnote no equal to in the upper limit as 160.5 rounds to 161\n\nfor any other degree of accuracy use the same method but to the appropiate decimal place

M16 fires a .223 -- in metric 5.56x45mm\n\nAK47's fire a 7.62x39\nModern AK's fire a 5.45x39 (NOT a 5.56 as incorrectly stated before)\n\nAn M60 I believe fires a 7.62x51mm NATO aka .308 Winchester

I actually have two barrels and recommend that everyone with an A5 have more than one.  I do this because you might not play the same position all the time.  There are times when your playing suppression fire and a flatline (about $100) will give you the range you need but you lose accuracy and then there are other times that you will want to play mid or attack and need the accuracy...for that, I went with a Smart Parts 14" barrel and I typically like to go with a mid-grade paint due to the extremely fast firing rate of the A5 (I have an e-trigger)...you could bankrupt a small country firing premium paint with an A5 + e-trigger set-up

Bound's Hubby here:\n\n"Boker" is absolutely correct!\n\nAs an important aside, do not think that the scope is going to vastly improve the accuracy of your SKS! The SKS is an inherently inaccurate rifle. I was firing a match a couple years back, and the match director allowed a competitor fire his SKS, until he was "removed" from the match when his rifle was unable to stay on a 6' by 6' target at 300 yards!\n\nI believe that of the two alternate scope mounts "Boker" told you about, the mount that replaces the rear sight would be the best. In order to use this scope mount successfully, you will also need a "Long Eye Relief" scope. \n\nGood luck!
