That is allegedly why springers in .22 are more pleasant to shoot, and why PCPs in .22 (at least at 12 fpe like the Brits use them) get better shot counts. The part about springs and seals lasting longer also makes sense. But why is it easier to make an accurate .22 barrel? I have never heard that before. If that is so, why are all the 10m guns in .177? I know that bore size has been mandated by governing bodies, but is it because it makes the sport more challenging, or what? I can certainly see why the trajectory difference can affect practical (not inherent) accuracy for many people, but I have never come across an argument based on internal ballistics or manufacturing realities. I guess it would take someone who either makes springers for a living, like a Weihrauch employee, or tunes a whole lot of them, like you or Bayman, to be able to comment. Someone else in the discussion above (sorry, the thread has gone on for a while so I can't remember who it was) claimed that something to do with barrel lengths will make a .177 more accurate in this platform. That was a new one to me as well.This is addressed specifically to Hector, but if anyone else has something helpful to say, feel free to chime in. It's almost turning into a masterclass in the pursuit of practical accuracy within clearly defined parameters!HA

Blinking just because people will be ending up with using the current JSBs and H&Ns. Why would you need more choice in .20 ? The Exact, FTT and Baracuda are proven in fit&finish, accuracy, balistics and most barrels like them. So you can add many more brands and types in .20, Exact, FTT and Baracuda is the way to go. Not only in .20 as you know btw....Not so long ago JSB even invested in- and launched a .20 Exact Heavy to the market.
Well ive owned both HW50s in 22cal tuned and HW50s in 177cal tuned. Both guns shoot smooth and quiet enough for no complaints at all. Both guns are deadly accurate with the 22cal flat out to 30-35 yards with good lead JSB pellets. The 177cal brings the flatness out further to 50 yards. I hunt alot of squirrels usually with my 22 rimfire. In the hardwoods shots could be anywhere from 15yards out to 80 yds. I sold the 22cal and bought the 177cal with Rons reasoning .I dont want to have to guesstimate elevation and drifts. things happen fast when hunting . A few seconds to shoot . Usually I go for the head to save the good meat from destruction from the rimfire. So ID say stick with the 177 which should be capable of headshots out to 50 yards and youll cover 90% of real field hunting experience. Dont fuss about the differance in the shot cycle.IF anything the cocking is abit harder than the sweet 30s. A muzzle brake will help ergonomically here .
