Thread: 6.5 x 55 Arch Improved Load Data

Honestly, I'm not really sure, but something in either IMR or Hodgdon, whatever is available (something very similar to AR2209.)

The cartridge is extremely accurate with moderate 2209 loads, but because the shoulder angle is blown out to 30 degree's, it can be a bit tricky with pressure problems. I tried some AR2213 a friend had in his loading cupboard, but it's too slow and caused pressure issues.
