Tominco's FX Crown (pic heavy!)
- Thread starter Tominco
- Start date
There you have a review of the Crown in .25 caliber shooting at 75m, it has subtitles in english but if you don't get something let me know as spanish is my native language. Cheers

Next weeks project...
Tonight I plan on taking the stock off (again) and beginning the finishing process.
Thanks for the posts guys.

My poor Crown....
Ever since day 1, it has been forcibly disrobed on an almost daily basis. This evening I prepped the stock and applied the first 2 coats of finish. Lots of intricate sanding on this stock. And, it's THIRSY too!
This is going to be a challenge if I go for the full 20+ coats.
But, it'll be worth it.

Thank you Tom for the excellent write up with GREAT detail!!! Outstanding job, and I am really looking forward to your continued coverage on this rifle. I have one on order and am anxiously awaiting it's arrival.
How is your stock coming along?

sweet, I can't wait to get mine. Had one in .25 calibre (full power FAC UK) on order since May.
Must ring the dealer tomorrow to see where delivery is

Tom I hate to mention this.........................but I have came to the conclusion that you have made a deal with the devil to get some of the stocks I have seen on your rifles! Keep up the nice work!

I have confirmed that the Impact regulator instructions work for the Crown.
@Goodtogo - When the devil comes to collect, I'll take him out with my Crown and have him mounted.

AoA sent me a temporary instruction manual which actually is the Impact manual. In their letter they state that the Impact and the Crown include "many of the same features as well as the same warnings when adjusting the hammer spring and/or regulator." The letter says more than that but, that's the main point of it.
Thanks AoA!

"Tominco"This is a page from my Impact journal. Sorry if it's a little hard to read.
Where did you get the digital gauge? I don't trust any analog gauges.

"Factory sets them with $600 digital gauge"
I don't actually have one. I installed a 2-1/2" gauge onto my Impact which I know is waaay more accurate than the stock ones. It's a risky move with the fine aluminum BSPP threads. With the leverage that's involved with a big gauge like that and all it's additional fittings, one accidental bump could cause very serious (possibly unrepairable) problems.
But... I took my time and was successful.
If you google "digital pressure gauge" you'll get lots of results.

HOW TO...
Adjust velocity on the FX Crown.
There's a lot of us that like to shoot the .25 cal MKII's at speeds that are in the 830's, 850's, 870's, 890's (shooters preference). The new Crown's are coming out of the factory shooting the MKII's at about 800's - 810's. So, how do we increase the velocity?
An owner might think that by simply taking out the slack from this sliding block (behind the power wheel) they'll increase the velocity to it's maximum potential. This is easily done by removing the power wheel and screwing in the setscrew that touches the cam on the back of the power wheel. Seen here...
True and not true, it depends on how far you want to go. Ultimately, it's a balancing act.
If you only adjust the setscrew, you'll initially gain velocity but as you adjust it further you'll start to lose velocity. If you adjust the regulator at this point, you'll start to gain velocity again.
While I admit that I don't have all the details on what specifically happens internally, I do have a theory...
The hammer hits the valve harder and harder as you adjust the setscrew. At some point, it hits so hard that it starts bouncing back and closing faster. By increasing the regulator pressure, you increase the resistance behind the valve. Since there's more resistance, the valve stops bouncing back. Since there's more air pressure, more air is able to escape and your velocity increases.
If you continue to increase your reg pressure, you'll end up putting too much back pressure on the valve and your velocity will start to drop again.
So, in my opinion, the best way to get more velocity out of the FX Crown would be to slowly increase both. A few turns on the setscrew, then a few bar on the reg. Then back to the setscrew. Then back to the reg. Think of it as if you were "sneaking up" on the fps you're after.

My opinion.... BUY THIS RIFLE!
I've had it for less than a month and the things I'm seeing through the scope are really impressive! I took a rifle that shot the 25.4's really well and tuned it to shoot them even better. I was, honestly, a little disappointed in how it was shooting the MKII's at first. But, after a little more tuning, It's now shooting the MKII's as good as it was the 25.4's.
That's one of the many reasons I'd say this is a rifle to buy. If it's not shooting the pellet how you want it to, you can easily tune it to do so.
The Impact was awesome for it's tune-ability and the Royale has always been a top tier shooter. If you smashed those two together, you'd get the Crown.
Forget the mag. Single shot loading is the way to go. I do have a single shot tray for it BUT, you can get by just fine without one. The scope sits high and the opening is large enough that you can handle load this without much difficulty.
Almost all of my shooting has been done at 100 yards. I bought this specifically as a long range shooter, and it's proving that it will be a good rifle for that purpose. I didn't plan on replacing my Royale (My #1 shooter) with the Crown. But the Crown has basically caught up to the Royale and, with a little more time and tuning, I have little doubt that it will become my new #1 shooter. Recent events suggest this is already happening... In my "Airgun Depot's long rangers" video, I began with my Royale and switched to my Crown when I hit 150yds.
When I talk about "the things I see through the scope" I'm not necessarily referring to the groups I'm putting on the target. I'm referring more to the flight and the rifles ability to stamp shot on top of shot, on top of shot vs a small group where every shot wanders a little bit. I don't shoot very well through the scope cam but, I'm trying to get some of this on vid to show all of you.
Regardless, my official review at this time would say that this is a "BUY" Rifle.
Happy Shooting!

I don't know yet. I've been shooting the MKI's. Like Teds suggests, somewhere between 800 and 860.

Funny, I had assumed that a higher reg pressure would be less of a stress on the regulator, with a lower pressure differential for it to deal with... Yet another thing to research I guess
