What is the air tube outside diameter on the Stormrider? Looks to be around 25 mm or 1".

Correct me if I'm wrong but it sounds like you are distinguishing these tight spots as different from a choke...a choke being a tight region that is usually 1/2" long or more. A spot that feels tight right at the muzzle is usually the result of a burr left behind from crowning. If so, the good news is that's usually a pretty easy fix with a brass screw and abrasive compound. SPA's reputation for mangling crowns precedes them so it would not surprise me in the least.The other clue for me is where you said:Quoteone of the barrels swaged the slug until the difference in the rifling impressions and the body of the slug were almost nonexistent.suggesting the burr may be wiping out the profile of the lands and grooves as the slug emerges from the muzzle.

PeterThe O/S diameter of my 17 cal SR measures right around .868", filled to 2900 psi. HTH's

Quote from: subscriber on January 24, 2023, 08:11:51 PMstorm tubeyour guess is right and there's around 5.5mm clearance between barrel and maintube, but would need a new barrel band too, i may have the file somewhere remind me to check tomorrow
A smidge less hammer spring should even that out IMO. No???
Maybe the reg has a slow recovery time?
Most Snowpeak/Artemis guns i've had through my hands using wood have all been literally drenched in plastic so called pore filler.This is what hands them that rather pöastic feel.Only reason for the doing it that way is that it's fast and thus cheap to produce en masse.Only way i know to get rid of it is to sand the stuff down.Done it to my Stormrider, P-15 and now my M-16.Pore filler gone i use a slight amount of dye to get that hue. Then, as you mention, a 50/50 mix of boiled linseed n turpentine.At first i apply it wet for as long as the wood takes for it.Then let it rest to cure. Yet another layer and this time i sand it too - lighter and lighter paper as I go.Final stage ( not done in the pics) a layer of antique wax or similar that you buff out.
