Question for FX Crown and Impact users

I have .177 and .22 barrel kits for my FX Impact. 

Admittedly, I mostly use the .22 barrel, but it’s nice to know I can quickly switch over if required, or I simply fancy a change. 



This rig has been first class since taking delivery 2 years ago this month... love the thing!

I have the impact in .25. I want to get the .22 barrel kit for it. Then I ask, why do I want to have an extra barrel, magazine, and probe in .25 laying around that I'll never put back on the gun? Once you get the gun setup, why would you want to change calibers again, unless you have a special purpose that makes it worth, say, putting a .30 barrel on it for some reason, sighting it in, and learning that caliber?

I think it's just too much hassle to switch over and setup the gun again. It's a great option to be able to do that, but in reality, just too much hassle.

Eventually I will put a .22 barrel on it, but it'll be an "X" barrel where I currently have a standard ST barrel. The upgrade will be as much for the new barrel liner system as the change in caliber.

That will leave me with a .25 caliber barrel I'll probably rarely if ever use again.

So, you can kinda see the logic. Great option, but rarely used. . . . . 

I suspect it'll be the same with the liners. People will settle on a liner and just shoot that liner.

You know what they say, beware of the person with just one gun, they probably know how to use it.

I would be interested in the 177 cal kit ..backyard shooting for shorter distance and queitier would be a win !
but a compressor is next.

Moving up to a legal hunting caliber or a slug gun would be the "why" for me!

I'll likely just get the slug barrel for my .22 and save myself the hassle of a whole new caliber change kit, mag etc. Pellets for day to day pest bird whacking and change to slugs when I need more thump and/or wind bucking ability. Depends on how they perform in average owners hands though - otherwise I'll do exactly as you say and stick with my chosen caliber, tune it up for whatever pellet I fancy at the time and stay there until I change my mind.

I bought mine for the quick adjustment abilities for different weight pellets, not necessarily different calibers, but that may change with time...??

Personally I would buy a whole different rifle .

Yote - gotta agree on buying a new gun - Since changing calibers is $400 for the barrel kit and $80 for the magazine in the Impact, buying a new gun might just be the best solution to change calibers -



Even if you want to stay with FX, a Streamline synthetic is about $1000. If you leave the FX Brand, the $500 to 1000 options are so varied, so many choices. The best part is that you get to set the gun up and leave it setup. So much better than converting one gun from caliber to caliber.

I have an Impact with the original 25 ST, 22 ST, 25 700mm X and just bought a 30 700mm X. Difference in accuracy between the ST and X barrels is so close that it comes down to my abilities on a given day. I really don’t use the 22 and instead just grab my wildcat for that cal. Both 25 barrels are great. The 700mm barrels use less air giving more shots per charge. I believe the original 25 ST is 600mm and when changed to the 700mm the gun has to be turned down to get the same speed. That’s where the extra shots come from. Bought the 30 cal barrel simply because I like the cal. I’m going to sell the 22 cal barrel simply because of lack of use. The gun has to be re sighted with and tuned with each barrel change, but that’s not a problem if you simply write down the settings. Takes about 5 min to change barrels and reset and it’s always come back to dead on. The barrel kits seem expensive, but it’s much cheaper then having multiple guns especially when a scope, rings and case are needed for each gun. It comes down to what you want. Sylvan

Great question blackdiesel and one l have thought about a lot. I do have a 25 cal Impact and have been loving this caliber after shooting a 22 HW100 for 8 years.

l have a 22 X barrel due very soon and wonder if l will enjoy it after Still getting a buzz using the 25.

I keep thinking that l would rather have a dedicated 22 of a different brand but they don’t offer the versatility of the Impact especially with the liners and hitting power of slugs.which looks like a game changer that so many of us are keen to explore. Time will tell and l guess we are lucky we have so many options with our hobby.

I look forward to more options on this.

I have both 20 cal crown and 30 cal inpact. On my inpact I have also a 25cal barrel kit but I don't use it much it's just nice knowing I can but really I keep on my 30cal. The one time I run out of pellets in 30cal I switched to my 25cal till I got some more in that was nice and it got more shots witch was also nice so I am like you it's a good thing for a small number of people for me if Iam going to switch caliber I want a new airgun it's what I tell my wife at least Hahahah.

I agree with others, it's a Pain to change any set up on your Impact. Because of what is required to tune it again. 
But!
Having that ability is great!
Or if you don't want you can have several guns already set up for different calibers?

Just depend on how much you want to work at changing calibers.

I picked the .22 because that is the most ideal caliber for my shooting needs.

BUT! I will stilll need to change out setting s when I buy the slug liners for my gun. Shouldn't be too bad.
Once I gather the data/settings for the regular pellets and the slugs I should be able to just switch to different liners and pellet wieghts fairly easily.

I don't have either of those guns but I swap calibers with my Royale all the time, best part is the .25 mags work well with the .22 pellets too. Only takes about 5 minutes to do as I leave the reg pressure the same for both calibers.

As for "tuning" I just set the HST in a certain position for each caliber upon reassembly.

The OP wanted to hear from people that actually change the caliber, not from people that just "think" about it. 

I guess people just like to hear themselves talk and do not really care about answering the question. I know. Trust me.

I'm a little late to the show, but have experience with all and pretty much what everyone else said.

I started off with a .22 caliber and learning on pcp guns. Then after 50k pellets I decided to buy a .30 caliber. Now at this time I'm still learning to tune and learning what is a good tune and when not to touch it. Over the many different tunes I put on the gun, there was one time when I had the .30 shooting at a speed that I liked and I had the .22 shooting at a speed I liked and both were very accurate. So, I'm mentioning this because it is/was possible. Since then, every time I'd switch to get the accuracy potential I KNOW is possible, I've had to change the valve stem length and not just the hammer. You could always measure the lengths and replace with ease, but today I rather just have two guns. Call it lazy, but usually I'd switch cals with the weather or what I'm shooting. Calm day, no wind, shoot the .22. Windy days, long range, shoot the .30. The ultimate would be a .25 and .30 setup. Now at first you say they're too close, but given the shot count available from the .25 and its hitting power with a 34gn it could be an everyday piece. Which I have actually switched to full time. Then you have the .30. .30 is great for it's hitting power and those super windy days. That added bc really helps with the wind. Of course you know all this. 

In conclusion, most people just want superb accuracy and even though with a nice gauge liked the edmu on the rear, you can easily get repeatable results, you just don't want to touch it when it's shooting great. So, just buy another gun.

I forgot to mention, on almost any setup the guns are at a minimum 1/2" at 50y. It's the longer distances that really need a good tune to be accurate and consistent. So you could always set the gun up on your favorite caliber ie. .30 and then what every you get with a .22 or .25 is what you get which like I said should at least be 1/2" at 50y. So if it's for backyard (suburbs), you just need to re-zero and your golden.

I have a Crown in .25......I love it. I have a .177 barrel kit on order, but I probably won't see this until Christmas. I ordered this kit because the .25 is too loud for backyard use. Since then though, I have made a moderator which is very quiet and backyard use is now very acceptable. However, the pellet impact of a .25 pellet on ANY target is too loud for backyard use and this is where the .177 caliber will help. Air guns are short range weapons. That's their advantage. I can regularly take targets at 80 meters. If I need to hit targets at longer ranges, I would use a cartridge weapon. I want my pellet to lose energy very quickly, that's its advantage. I think using slugs and striving for long range service.is unnecessary and in the end, self defeating.
