Did not want to take up space on the other thread. How many rounds are we looking at before the barrle is gone? Just curious if anyone has a guess. Thanks.

yes they are the same. overbore...yes. fast...yes.. what you will gain... burnt out barrel. you could load the 25/06 with the lightest bullet possible, experiment with different powders/ primers, and more than likely acheive the same thing.JMHO

  It depends. My cousin has a 240 Weatherby which is virtually identical to the 243/06. He's had it about 20 years, shoots at most 20 shots at a time (in one day), so the barrel never gets overly hot. It's been fired at least 500 times and probably closer to 1,000 times and the throat is still fairly bright- a long way from being burnt enough to affect accuracy. The thing that really gets to a barrel is to get it hot and then keep shooting it and on a microscopic level, melting the leade and first few inches of rifling. As noted, the cartridge is "overbore", but that doesn't mean that it will be rapidly burnt. It could be burn in a hundred or two rounds if you lined the bullets up and fired them in a couple hours; but if you take care to keep the barrel cool, it will last at least a few thousand rounds (provided the rounds are not generating pressures beyond the guns design).

  An older family friend was a Wby fan. His favorite was the .240. I know positively that his "pickup rifle" had been returned to Wby twice for a new barrel so it was on it's 3rd one when the old guy died. He did shoot quite a lot but only a few shots at a time-mostly deer, coyotes, and frozen cow pies.
  For many years I really wanted a 6mm06 until I discovered the 25/06.
  Heavier bullets,factory ammo, and better barrel life.

  old school method was 40 lbs of gun powder so 60 gns/round times 7000 dived by 60= 4666.........but the .243/06 is greatly 'over bore', I'd give it 1000 rds tops

  Properly cared for, it should shoot 3K before accuracy starts to fall off.

  EhlerDave,
  
  I didn't know if you saw it, but I posted a close proximity on the other thread as I shoot a 6mm-.284 of about the same capacity. Slightly less maybe by a grain or two.
  
  I had the most erosion when I was shooting it in competitions. I had to set it back about an inch each 1000 rounds. I haven't shot it 1000 rounds since I last competed. The gun would get hot and I think that is where the erosion came from.
  
  But, for limited group shooting and times when you can let the barrel cool, the round count will go way up before having to set back.

  golferboy426,
  
  quote:what does that mean, set it back an inch
  
  It's a technique used by gunsmiths to correct chamber/throat problems in bolt action rifles.
  
  We remove the barrel and set it up in a lathe in order to remove a certain amount of barrel material at the breech. Small corrections might be 1/16" or 0.0625" in order to bring the barrel back to top dead center when working with fairly standard 16 TPI threads. If someone states that they want a sizable portion of the chamber removed to get a significantly new chamber, the entire thread tenon is cut off which is about one inch in many cases. This lets the gunsmith start fresh with threading and gets the owner most of a new chamber.
  
  Best.

  Thanks guys for the replies, I was also going to ask about the set back but was guessing what it was.
  
  Sounds like a fun flat shooter.
