Hi,
I have the CF barrel tube so I can fill to 250bar. With that, at my current tune, I am getting around 90 shots before falling off the regulator. I have the reg set at 110 bar. This has been one of the areas I have spent a lot of time working on. The DRS is really intended for higher power than 20 fpe. I think the valve return spring could probably be a little stiffer to help close the valve quicker. The valve is almost exactly the same size as in the Crown, but the spring is different.
When I ordered the FORM stock (from the UK maker) having a UIT rail is on option. So are the cheek riser and the adjustable length of pull. I opted for this stock (two other style options) with the cheek riser and UIT rail, but not the LOP adjustment. I 3D printed a plug to get the LOP where I wanted it and to allow the PRS butt pad to work. The stock isn't cheap - more than the FX Grade 2 walnut option. But I like it better. Not as much as the GRS stock on my Crowns, but almost as nice.
The 30yd/40yd Challenge is a bench shooting challenge. There are guys using fancy benchrest front supports, but a lot of us just use a Bipod and a bag or monopod. Mike (from Thomas Airguns) has reported using a remote-control trigger on some of his cards. I have shot a few from my HFT position. I am going to ask Ed (EPG, the thread moderator) if we can add an HFT class. I think the rings on the targets are way to small for offhand.
Cheers,
Greg
