Snowpeak Max 1 power disappointing

SPA does not always overpromise fpe. I just looked at Krale to be sure my memory is working and SPA advertises 22, 34, and 46 Joules for P35s in 177, 22, and 25 respectively. Mine will nearly make those numbers in fpe. My 177 easily makes 19 fpe, and the 22 is happiest at about 32 fpe. The 25 is more complicated but will certainly exceed 34 fpe. I have made some changes and it is giving me as much as 60 fpe. But it won't come close to that stock, low 40s is probably about the maximum. Point is SPA under estimates fpe in the P35.

I have no clue about the Max 1, never seen one. But one of the changes I made in my P35-25 was opening up passages in the gun and it helped.
