I was wondering the same thingI wonder what the peak pressures are for 200+ grain bullets leaving a .308's 22 inch barrel over 2500 fps.

It's my opinion and experience that any well built rifle barrel fit properly to a receiver will shoot just as accurate starting with the first one from a cold barrel to the last of a 30 shot string with shots fired every 30 seconds. At most, the last 25 may center at the longer ranges 1/4 to 1/3 MOA above the first 5. But that's due to powder fouling causing higher muzzle velocities, not barrel temperatures.With the 225gn hornady's do you think you could make consistant cold bore shots at 1000+ yds from day to day or month to month?
