"amoxom"BSA R10 mkII any day. It is regulated and super consistent. This is the down fall with Daystate... Very few from the factory regulated airguns.
look at the review that Giles did on the Airgun gear show on YouTube. Granted, it was .177 and UK spec, but still, that gun kicks ass, and is also cheaper than the Daystate.
What he said. I've come to the conclusion that being regulated is one of, if not the most important factor in accuracy. I have a BSA R-10 MKII in .22 and it is one of the most accurate guns I've ever shot, out of about 15 or so different PCP's, some more than twice as much.
I recently had a Daystate Wolverine (not regulated) and did an experiment. I shot 8 consecutive 5 shot groups at 50 yards. As the bell curve increased due to not being regulated, the shot patterns on the target rose with it. And vice versa, when the velocity decreased and the shot curve started to come back down, sure enough the groups started to fall on the target as well.
Accuracy aside, being regulated will usually get you a higher shot count also.
Also, don't let the lesser price fool you, the BSA is a fantastically built gun and compares in quality to much more expensive PCP's. The stock is quality walnut made by Minelli.
If you were going to consider other guns, I'd also give a ringing endorsement to the FX Royale line. You will get a huge shot count, regulated, adjustable power, and it's the other gun I have that I'll likely never part with because of how accurate it is. The recent price drop makes them a compelling choice IMHO. Regardless, the BSA R-10 is right there at the top of my "highest recommended" list, for what that's worth, haha.
Good luck with whatever you choose!
