Started with 16.7gr H110 and worked up to the following -
150gr FMJBT, 17.2gr H110 - works well, primer's looked great, rounds cycled fine - no FPS readings since I'm minus a chrony at the moment.
150gr FMJBT, 17.4gr H110 - also cycled well, showing signs of pressure.
150gr FMJBT, 17.7gr H110 - too hot, started to flowback and flattened out.
No grouping was attempted with these, just a basic function check and check for pressure signs.
