1000yd crow cartridge

Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. A mate of mine built a rifle for a 1000yd crow. The cartridge is a wildcat 6.5x68 with the shoulders blown out & forwards to become straighter-sided and...erm... bigger. Had one in my grubby mits earlier - it's a beast!

    Dunno what velocities he's getting, but the parent cartridge already could do >3200fps in the 1940s, so this bugger's shooting fricking laser beams. Apparently the case is good for >72000psi! Beats the kak out of 6.5x284 in any case.

    Mate's client got the crow, by the way!
     
  2. Short barrel life then? :D
     
  3. APFSDS?
     
  4. Few rounds down range and he will have a nice smooth tube to ease the passage of any projectile.

    Might be enough to develop a load - just :D

    So, rifled slugs is it?
     
  7. Apparently he's put 600-odd rds through it with no obvious signs of smoothness yet! My thought was the same though, this cartridge must eat throats for brekky, lunch and dinner.

    The chap's got more money than sense, so does it really matter if he burns the barrel out after 1500rds or so?
     
  8. stoats, any load info?? powder charge, projie weight and MV?
     
  9. Not to hand, but I can ask
     
  10. 63gn 4350, 140gn A-Max, don't know velocity
     
  11. The above load does 3300 ft./s

    apparently he has had it up to 3600 ft./s with the same bullet without any overpressure signs.
     
  12. Have you got any pics? Is it a "tube" gun?
     
  13. No, I have not personally seen the rifle, although if my memory serves me well it is a Winchester 70. No idea what stock is on it, but the tube is over 30 inches (the customer is always right, remember...)
