  This NOT from Sierra.....
  
  
  250grHPBT and 88 grains of H1000 gets you 2570FPS
  
  250grHPBT and 98 grains MAX. of H1000 gets you 2850FPS
  
  
  Hope this helps a little.

  Interesting...... The Hodgdon charts show your loads as if it was a 215 grain bullet. Wonder why Sierra and Hodgdon are so far apart???

  I think boat tails and flat base bullets take the push differently
  that might be one factor.
  
  
  That could be true. Years ago, I was doing some very intense testing/reloading for the 22/250 Rem. and I sworn the very radical angled base of some boattails had lower pressures than a similar flat base bullet.
