New gun .22or.25?

I’m going to be getting a new impact x as soon as I settle on what caliber to get! I have a streamline .25 so I was thinking a .25 impact, then I only have to stock up on one size of ammo. But with all the advances of the 22 slug, plus being able to push the 22 little faster and still get a lot of shots per fill got me thinking 22 might not be a bad idea. what are your thoughts? I am a hunter first to if that makes a difference small game up to raccoon size so really a well placed shot with 22 or 25 will easily take down my target quickly. Just looking for y’all’s opinion before I spend the money. Thanks
 
A .22 will do the trick most of the time but you gotta love the power of the .25 for hunting...especially as you move up to groundhog/racoons sized critters.

One nice thing about the Impact is you could always add another barrel kit later on. :)

One other thing, while .25's aren't readily available at your local Walmart, there are designs to cover the entire landscape of needs, including very good expanding pellets like the Predator Polymag and hollowpoint slugs, if your airgun likes them.
 
I have and and LOVE the.25 for a variety of reasons. I am a hunter as well and I love the ability to take down with out a guess at 100 yard for small game like squirrels.. Not to mention the energy that is dumped on the animal with a .25 when tuned right...I have had all types of 22's and I was so excited when the 25 came online.....It boils down to a big piece of lead, bigger energy dump.....in my opinion...
 
It sort of depends on what size critters you are hunting and the amount of pellets or slugs shot. With the availability of the new FX Hybrid slug we finally have a slug that will really expand on smaller game and pests but then they are more costly to shoot. If you are not wanting to spend that much on ammo compared to the FX slugs then I say go with the .25 cal. bigger hole and more take down power. Bill
 
25 all the way, split the difference between 22 and 30. In my mind the best balance when comparing the 3, but I shoot pellets only. Not as cost effective as a 22 but a lot better than a 30. Power better than a 22. Or as good as a 30. Sound of as quiet as a 22 better than a 30. All around cost better than 30 shooting pellets and better than shoot 22 with slugs.
 
What`s up Ginuwine.

I am in the market for another airgun also. I have a few pcp guns, one .22 pcp, and a couple .25`s. Been wanting an FX Impact, .22/25. I want to shoot longer distance. I am thinking the .22 will get the job done, but .25 will deliver more energy on target. Slugs will be the ammo of choice. Thinking, thinking. Will make a decision soon.
 
 I’m going to pull trigger on the .25. Here is why, with the power plenum, and the 700mm barrel 100+ shots per fill with kings should be no problem, I’ll be able to crank up the power with slugs and get 30 cal power with a better shot count, I mainly only shoot squirrels and rabbits with the occasional raccoon or woodchuck. In the past with my m-rod, bobcat, crown, cricket, and streamline all .25cal I have not had a problem with quick clean kills Out to 75-80 yards on a woodchuck, also most if not all my rabbits and squirrels have been at less than 50 yards. If I want to take something bigger like a coyote I’ll spend the $450 on a .30 kit or get out a powder burner. 
 
The type of shooting should always dictate the caliber. Bigger quarry or really long distances? Increase the projectile size.

Shorter ranges or smaller pests, any small-bore will work.

There's a few factors that are worth considering: as others mentioned, we have a lot of options in .22 from slugs to pellets, and hybrid slugs. You can even buy NOE molds and roll your own. .22 costs less as a rule. You get more shots as a rule. You have more choices as a rule.

Still, let the type of shooting the caliber. and be honest with yourself.
