Back in the day when the 220 swift was really popular, people were loading them up to muzzle velocities of 4300+ FPS. It was insane, and these were the ones that got the barrels shot out in a year or two. I have owned both calibers, and for me, the 22-250 is the most accurate round I have ever shot. Better than my 6PPC as well.

My buddy and I were sniping California ground squirrels (Otospermophilus beecheyi) in Nevada, shooting up to granite boulders in a steep box canyon. Buddy shooting 22-250, me 223 (both R700s). We were sitting close together on the ground, elevating using shooting sticks, taking turns spotting for each other. While I glassed, waiting for him to fire, I heard a "tink" followed by "Damnation!" He had groped for a round out of his cartridge box while watching a squirrel through his scope, but grabbed a 223 round out of my box by mistake, chambered it and pulled the trigger. There's a lesson in that story somewhere.

Howdy!
6PPC has a rim diameter significantly smaller than that of .308-family brass, and larger than .223 rim diameter.
Rim diameters are called out in reloading books, and even on Wiki notes given for many rifle cases
A PPC oughta work ok on groundhogs for the distances you mentioned.
You can plug n’ play velocity numbers and bullet weights of various combos into the on-line Powley Computer; and compare results. Sample PPC velocities for various bullet weights can be obtained from places like Hodgdon’s reloading data site.
As mentioned previously, I myself use 450ft lb as the minimum energy threshold value when considering loads for use on groundhog; for whatever range is being considered. You won’t be low on energy when using an appropriately constructed varmint bullet of typical varmint calibre s (IMHO)

I would put heavy weight on Alex's recommendation of a fast twist with light bullets for tremendous explosions. I witnessed this with a 7 Twist H Br running 55g Sierra bthp(tough bullet) on p. dogs.
I used zero freebore- .058 reamers with the 6 PPC's.
