Hi all!
I recently purchased one of the Sig Virtus Pcp rifles and have been very pleased with it. I have had only one issue with it where I had an out of round pellet that worked its way forward in the magazine belt and bound up at the chamber. Easy fix, just needed to seat the pellet back into the belt with a range rod. After having fired close to a thousand pellets through it I was impressed with how smoothly it shot and it is surprisingly consistent with most pellets that I have run through it ranging from 14.3 up to 18.21gr H&N Barracudas, some cheap Crossman premiere and some Nelson slugs. All of them shot well and group well. The only thing I felt was really an issue was the power, or lack of. I would not suggest what follows if you are not experienced with pneumatics, regulators, and gunsmithing. I decided to open the rifle up and inspect the action and operation to decide if it could handle a bit more power. After inspecting the internals and tolerances I felt like it would handle a few more psi from the regulator and slowly started to increase the output by rebuilding the Bellville disc spring. I started by adding a single twenty thousandths shim to the base of the stack which bumped it up about 40 psi at the output. It was an improvement, but I still felt it could use a bit more. After trying a few different configurations of disc and shims and testing the psi output of each I settled on adding one disc and one shim to the factory stack and ended up at 1480psi. For me it is a marked improvement over factory, it is much harder hitting and I have had zero issues with "flyers" or inconsistencies with accuracy which had been my main concern with increasing the output. This rifle was never designed to be a long range tack driver, more of a fun plinking gun. That said it has a ton of potential for improvement and in my experience benefits from a little increase in power. For now I am pretty happy that it will hold 1moa out to 50 yards, I haven't set up a known distance range farther than that yet for better testing. But you can bet as soon as I get my chrono back from a friend that has been borrowing it I will get out and do some more accuracy tuning and report back with a more detailed update on its performance if there is any interest in it.
