    Seems a bit low but they are really simple to up the power. I don't want to talk about it on an open forum so will drop you a PM.

    180 bar might be a touch high and off the 'sweet spot' curve, so giving you a low reading. Try chronoing it at 150bar.

    On mine the sweet curve also was at 150
    Filled to 165. For a comp. Few shots on the zero range. Then on we go

    Thanks for all the advice I also asked Graham at Anston Ftc and he mentioned the power adjuster as well. So I turned the adjuster fully in and out and then put the gun through the Crono. I eventually ended up with 11.4 ftbs which I was very pleased with. Just got to get to club and check all my turrett settings

    My MPR FT is an old girl now and she is probably the most accurate rifle I have ever owned. I fill to 175 bar and shoot down to 120 bar. The only problem is that she hates hot weather and the power spikes.
