Mine's dropped down to 257fps so I'm guessing something's amiss. Another collector also tested his WRHP and it was only doing 135fps, but he thinks the breech seal needs packing out. I suspect the breech seal may be a weak point in the design and may flatten out beyond the point at which it's being compressed. I might have a look at mine over winter.

I was very surprised how accurate it was though.

Cheers,

You are such a great shooter you really value all the characteristics that add to the pistol’s accuracy etc. To me the HP being a 1907 and so well built is a treat just to hold and look at! Same appreciation I have for 1800’s black powder pistols.
