Results - Tulsa FT Match 13 Apr 24

Tulsa Gun Club conducted our Inaugural match on 13 APR 24. We had a reduced number due to the Cajun Grand Prix this weekend, we know everyone will enjoy a very well run match there. At the 9:30 match time it was a very comfortable mid 60's temp and just a hint of wind that slowly grew during...

I have mine bedded all the way but you could also have the block bedded and just bed the end of the forearm to support the barrel. This is how a lot of PB rifles with synthetic stocks are made. I think the barrel should be bedded to the stock on the DRS . Just makes the whole platform solid which should help with accuracy . I believe in torqueing the screw to a constant value every time you take the action out and put it back together again. That’s for all guns.

I saw in a review that if you loosen the hinge screw slightly it will fix the wobble making it very solid. It was opined by the reviewer that later versions got fixed being very solid I guess.

Over the years, I’ve neither found nor read any meaningful evidence of O-ring problems arising from degassing and refilling. At least not in the usual circumstances where the user does it occasionally. However I have become aware of a particular sort of heat stress and degradation affecting the seals at the high pressure end of a regulator. Speaking of the O-ring on the small end of a regulator piston and the one on the adjuster (when applicable). This heating occurs each time the regulator cycles, on account of the pressure drop of firing (cooling) followed by the pressure rise of the refill (heating) of the plenum. It slowly and gradually cooks the O-rings, so to speak, and they eventually become hard, brittle, and incapable of sealing properly.

So how does this normal, unavoidable heating effect from ordinary use relate to the occasional degas and refill? As in, does one have a disproportionately greater effect than the other? Well, I guess it just depends. For example, although a complete refill from zero clearly produces a greater temperature rise, this situation is not happening all that often. Whereas the heating from normal use is happening probably hundreds or thousands of times for every 1 time you do a complete degas/refill so my intuition is not to fret over it. Besides, it’s unavoidable that someday the regulator will need to be serviced. Other O-rings too. I mean of course you don’t want to needlessly hasten it but worst case it’s just an inconvenience when the day comes.
