Re: Load development COAL problem? 22-250
Not to worry, I am loaded 2.455" with a 55 Berger Varmint bullet. I don't recall how far off the lands that is, but it's not touching for sure. Same rifle as yours.
Your throat may be a little longer than mine, but that is a really nice thing about the 22-250, we can seat them long and still have a highly accurate, magazine fed rifle. As the throat erodes from firing, we just seat the bullets out further to compensate.......up to a point, at some point we have to set the barrel back or re-barrel.
Saami specs are just a guideline for the unknowing. So long as you start with a reduced charge and work up, you shouldn't have any issues.
I always start with the bullet just touching the rifling if it will fit, then once you find the powder charge, you can back off/adjust the OAL and pressures usually go down slightly if anywhere. Only the rifle/bullet combination can tell you what depth to seat the bullets at for best accuracy. The book is useless for that information, it doesn't know what rifle you're shooting, or what reamer cut the chamber, or how long the throat is after firing 1000 rounds.
Aim small = Miss small
