Unlimited sighters and 20 rounds for record (Any Sight)
2 convertible sighters and 20 rounds for record (Any Sight)

*F class will have 2 convertible sighters for their third match

2x1000 (yards): Two 20 shot matches (plus sighters) at 1000 yards
Unlimited sighters and 20 rounds for record (Any Sight)
Unlimted sighters* and 20 rounds for record (Iron Sights)

* F class will have 2 convertible sighters for their second match

"Palma Course":  15 shots (plus sighters) at each of 800, 900, and 1000 yards

800 yards- unlimited sighters, 15 shots for record in a time period of 25 minutes

Palma Course

Traditionally a Palma match is limited to .308 or .223 caliber rifles and is shot at 800,900, and 1000 yards with metallic sights, and some additional restrictions.  However not everybody owns a Palma rifle:  CIHPRS' Palma Matches will be open to all of the traditional classes of rifles and F-Class.  

800 yards- unlimited sighters, 15 shots for record in a time period of 25 minutes
900 yards- 2 convertible sighters, 15 shots for record in a time period of 22 minutes
1000 yards- 2 convertible sighters, 15 shots for record in a time period of 22 minutes

Will my rifle work at 1000 yards?

There are no hard set answers as what will and what won't work however there are some general criteria we can follow.  

First criteria if your rifle or ammo meets any of the following the answer is generally, no it will not work
  • Using hunting or Varmint bullets, don't try it only use match bullets
  • A rifle with barrel length shorter than 20 inches.  Standard loads will not be able to get the needed velocity and if a load can it probably is not safe to shoot.  
  • A .22 caliber rifle with a twist slower than 1:8.  Your rifle will not be able to stabilize the heavier bullets.  Some factory 6mm's and 6.5mm's will have twists that are to slow.  For a 6mm such as a .243 Win a twist of 1:8.5 or faster is recommended.  For a 6.5mm such as a .260 Remington a twist of 1:9 or faster is recommended.  
  • Shooting 168gr Sierra Match Kings or Nosler Custom Competition bullets.  This is due to the angle of the boat tail design which causes the bullets to tumble as they go transonic.  Other 168's will work since they have a different bullet design.
  • An AR-15 can get to 1000 yds. but you need to push the bullet really hard and it is not recommended for the beginning shooter.
Second criteria we need to make sure we have a bullet that has a high enough ballistic coefficient to get there ok.  Bellow are some following criteria.

.22cal- If you must, any match bullet 80gr or higher.

6mm- Any match bullet 105gr or heavier

6.5mm- There are a lot of choices that will work.  The 130gr Berger VLD is probably as light as you want to go with the Lapua 136gr and the bulelts in the 139-142gr range being better choices.

7mm- Any match bullet 168gr or heavier

.30cal- Any match bullet 155gr or heavier (excluding the 168gr SMK and Nosler Custom Comp).  However special note the 155's need to be pushed fast mentioned below


Ok so now we have a bullet selected, for the third criteria we need to make sure our cartridge can push it fast enough. But before we talk numbers let me say, speed does not mean better.  It is where your gun shoots the best.  Just because someone claims to have some 6.5mm ultra super cartridge that can sling 142's down range at 3,200fps doesn't mean his is better.  DO NOT get caught up playing the speed game.  

Bullet  Velocity 
.22cal 80gr SMK 3,000 fps 
6mm 107gr SMK  2,850 fps 
 6.5mm 142gr SMK  2,620 fps
 7mm 175gr SMK  2,580 fps
 .30cal 155gr SMK 2,950 fps 
 .30cal 175gr SMK  2,580 fps

The above are just general guidelines that if your rifle/cartridge combination can get there you will keep the bullet above Mach 1.1 or higher.  

Ok fourth and final criteria we need to make sure our sights have enough elevation.  If we use the above velocities you will need the following elevations from a 100yd zero

Bullet  Velocity 
.22cal 80gr SMK 33 MOA
6mm 107gr SMK  30 MOA
 6.5mm 142gr SMK 34 MOA
 7mm 175gr SMK 33 MOA
 .30cal 155gr SMK 34 MOA
 .30cal 175gr SMK 42 MOA

If your rifle can meet all these criteria then you "should" be able to reliably make it to the 1000yd target. There are a lot of cartridges and bullets out there.  If you want more specifics as to what works best talk to experienced shooters at the match.  If you want to know why stuff works read the following book written by Bryan Litz, Applied Ballistics for Long Range Shooting.
