Soon I will be working up a load for a mod 70 win I'm having made up in 270 WBY. I want to shoot a 130 gr-- thinkin accubond or Interbond. In the meantime I have 130 gr SSt's for breakin and practice (cheaper) yotes, etc. I have all the usual suspects for powders 25,22,7828, tumbo, magnum, etc. My question is " Is there a sweet spot for the 270 wby on oal?" reason I ask is how weird it is that alot of 257 wbys are more accurate with a shorter OAL than one would think prudent. Both of mine are anyway. I kind a view the sweet spot for the 257 to be 3.150 to 3.250 depending on the bullet used. The gun will have a saami chamber and throat. I shoot barnes tsx's in the 257's so I kinda want to stay with a sleek bonded core with this one if possible. Any loads would be appreciated also. Don't worry. I work up my loads from below for "MY GUN".
