30 Cal for medium sized animals?

Absolutely a .30 can do vital shots better. Don’t get me wrong, a .25 can put down coons just fine on a double lung or head hit at close range, and a magnum powered .25 like a Condor spitting out a highly expanding 25 slug at very high FPE for max bullet expansion and wound channe damage can do it even better to bigger animals and futher range. 

But a .30 can do it more quietly and more efficiently. As where most .25s have to strain a bit to get to 70-80fpe or more, it comes natural to most .30s out there. You also get a bigger hole when using pellets. Even if all your pellet does is punch a hole from side to side of the lungs, a .30 hole is a big hole. More and more .30 options for ammo are hitting the market every few months. Swaged slugs are starting to appear. I’ve had a chance to shoot some for R&D purposes but not into a varmint yet. 

So yeah, IMHO go with a .30. Its the best all around caliber in my opinion. 

Your .22 Streamline on high power should be putting out over 30 ft/lb of energy.... more than enough for your skunks and such.

I've taken out 3 raccoons in trees at distances between 28-45 yards with headshots with a Kalibrgun Cricket in .25 caliber putting out 50 ft lbs and they were dead by the time they hit the ground. That being said, I highly recommend a .30 cal PCP for the kind of work you're considering doing. I've shot everything from .177 to .30 and the .30 is my favorite for pure hunting.
The Matador R5 .30 and Predator Polymag is my favorite hunting combo inside of 50 yards.
My latest hunting is exclusively with the .30 cal due to its increased power and quietness. You'd have to be pushing a 25 cal pellet above 900+ fps to achieve something close to 60ish ft lbs with a lot of noise generated by the increased velocity. I'm shooting my Matador R5 at 850 fps, which is relatively conservative at 71 ft lbs, and it's quieter than my Cricket .25 shooting at around 950 fps.
Supposedly the Cricket .25 shoots Polymags well too inside of 50 yards, but I have not tested it yet myself.

But is that enough energy for a vitals shot? And then there's the distance.....let's say 50 yards.....the 22 wouldn't be pumping out 30fpe at that distance.

I'm not sure its a matter of energy. You've probably got enough energy to send the pellet thru both lungs on a coon sized animal out to a reasonable distance. Its just that the .22 is making a very small hole when you do so, one that could easily clot. The bigger the hole, the more trama to the lungs and the less likely they will clot and recover. 

The BT 65 is a great rifle. I highly recommend to go get it at B. Walton (www.bwaltonpcp.net) he sells it tuned for 920 FPS zeroed in so when you get it, the rifle will group under 1"
at 100 yards. The factory LDC is good but he also has his own and the DonnyFL LDC which will drop the decibels down to the low 40-42DB and that is super quiet.

With his tune

Another issue worth considering is the cost of .25 ammo versus .30. It is not insignificant if you plan to shoot enough to enjoy your gun purchase.

just my opinion..these 25 cal pellets for my crown..would take down big prey..they are big...anything bigger Caliper you need to go to Africa to hunt.

Ted did a review about the 25.. and said it was his " caliber" of choice.. made a whole lot of sense.. to me anyway.. I think you made the right choice.. just swap out that stock with your 22 cal.. when you take it afield as to not scratch it.. .. 
All the best.. we expect a full report and video, please sir.. 

"Bob_O"Yes, I'm very familiar with that video!! Actually most if his vids...LOL!!!
And yes I definitely will swap stocks if the 25 is going to see any dirty work, otherwise I'll just have the 22 do it. I don't plan on retiring the 22.
I have a couple of videos planned for both Streamline's. ;-)

Awesome, looking forward to it!

Bob. I watxhed your dairy farm hunting video on a large screen ( I was watching from smart phone) Wow some great footage and excellent shooting. Especially in those conditions. I noticed it looked like a Vortex you were using in one video with cross hair reticle. Then a "mildot" reticle, what is the scope with the mildot reticle? Thanks Mark 

Nice..looks like you've gone nocturnal..
