I outshot my friend today at 300Y with my 25 cal Uragan King PCP in 25 cal using swaged slugs on a 7" diamond which I hit 4 times in a row. He was shooting his Anschutz 54 22rf with RWS target rifle ammo.
The difference was the wind stayed constant for me. I was using 2.4 mils of windage and my ES is around 10 fps. His wind hold is about half mine but his vertical is more.
It was a good day for me, I hit the 2.5", 2", 1" spinners with one shot each and also threaded the 1" bell target, all at 100Y. I usually don't hit those 1"ers on the first shot.
The thing that pisses me off about PCP airguns is POI shifts. Usually it's due to things like, shrouds, barrel bands, or frailty in the system.
Mikes BR rifle he used for N50 is the opposite, it's over built. It has a one piece and a thick action and a top of the line Muller barrel. It's highly tuned as good as it can be as well and he was tethered to the tank.
22rf's don't have POI shifts near as much PCP's do, especially Vudoo's, etc. Take my word for it!
Most PCP's are made for hunting not target shooting. I'll be so excited when the day comes that a powerful PCP repeater is made that will send .2 BC projectiles/slugs at 950-ish fps and is overbuilt like Mike's, about as precise, and of course lacking POI shifts!!!
One of the worse POI shifting PCP's I've owned was a FX Impact. I never figured out how to correct that. It amazes me that those skinny barrel liners centered with orings in a shroud can hold zero long enough to win a match with but those guys do quite well at RMAC with them.
