For the original stated purpose of backyard plinking a .177 will do just fine. But let's face it we all eventually convince ourselves that we really need the one that catches our attention the most. It doesn't really matter in the end what we need. It is what we want that counts. My 30 is a .177 and it does everything I want a 30 to do.
I would like to add a little something for the "lowly powered HW30s in 22 cal. First off if it has the vortek kit in it its an 8.5ft pound rifle. Low 500s with a 14.3 gr pellet. What can that do in hunting. Well Ive had crosman 1322 pumper with a few slight mods and stock barrel to match that power and Ive had the Crosman 112 bulk fill CO2 pistol shooting 510-520. Shots at crow at 30 yards went fully thru dropping the bird. Bunnies, and squirrels and pigeons out to 25 yards all fell to my 2 air pistols . I also own an R7 in 177 and while i love the gun for its flat accuracy out to 30 yds shots on game are a 50/50 proposition. You can hit right thru them but the damage is very small and they rarely drop where hit. Ive had to chase down far too many for this little caliber. It seems I get that even if the power is 700 or 800 fps . they zip thru the chest hit but the animal takes off. More likely to die but they can stay hidden . Who wants that. So whoever said 22cal is more for hunting is correct. Not to expect anything less on paper at the right yardage but then thats what this challenge was all about- yard work /short range. One other thing, youd better check the trajectory charts again. theres no 1.5 or 2 inch drop anywhere from zero to 25 yds with a 500fps 14.3gr pellet. I get plus or minus 1/4 " from 8yds to 25.
I bought my 30 in .22 for targets and linking. Almost all of my rifles are in this caliber cuz it's just much easier for me to deal with in the larger sized pellets.
Brett I have a 30 in .22 and have a stainless .22 en route as we speak. I love the .22 cal. I’m a plinker. Don’t mind the looping. The gun is accurate. Would I use on game, not a chance. Especially in winter with snow, you can follow it with a scope. Dead nuts on every time.I like the 30 and have a few because as I age the 30 with be far more practical to use. Crow
