Has anyone shot a crown under 20 fpe if so what was the accuracy ? my wildcat likes jsb but it likes them hot at about 28 fpe i want a crown in 177 cal but thats a 60 to 90 days wait
Shoot mine with JSBs regularly at 14-16 FPE I can shoot a 22 caliber pellet that I've placed down by my target with 0 issue. Of course a nice scope helps

I don't think it is unfair to say that a given pellet through a given choke and at a given twist rate will have a "sweet spot" for accuracy, both in terms of absolute accuracy and in terms of minimizing wind drift. (real world accuracy) So really one would expect, with a Crown or any rifle for that matter, a certain reduction in accuracy if you move off your peak tune.
That said, I've dialed my Crown back with the transfer port and not had any accuracy issues. I'm afraid I've never tried a statistical investigation of how it changes group sizes, because when I'm shooting for keeps I run full power, but I've not noticed anything going wonky. I hope that helps.

I understand STO I shoot a bench rest competition and my wildcat likes um hot to stay under the 20fpe I gotta slow it down and I lose to much accuracy so I am gonna buy a 177 so that I can stay under the 20fpe the only other advantage to shooting the 177 is scoring using the score pin

Given that a whole new rifle will be quite a spicy purchase, you might consider trying the pellet B liner on your wildcat before investing in a whole new rifle. It might not ultimately be the silver bullet you're looking for, but I'm betting the faster twist rate it runs will help stabilize pellets better at lower velocities. Just a wild guess though. I sort of figure 100$ for something you can probably sell again on the classifieds if it doesn't work out is worth a shot before dumping a couple grand into a new rifle, optics, etc.
Just throwing ideas out there.

The original Crown rifles sent to the UK market at 12FPE were terrible, the latest models shoot extremely well at these levels, most use the JSB heavy 10.34g.

Played with mine the other day WAY down in power. Reg I left at 130 where its tuned to. Went with the transfer port to 177 and hammer from min to max and transfer port at 22 and hammer up and down. At 27 yards, my back yard range groups were still good with a bunch of pellets. 500 fps minimum with a 21 gr pellet and a bit more with the GTO's. Nice thing is two quick turns just that fast and I'm back to the tune for 18.13's, takes me longer to type than do.
