.30 is soon to be the new .25
Yeah, we airgunners can be greedy when it comes to power rkr. & you do have a point to a degree about it being hard to compete to fill the gap between .25 & .357 But what most larger bore air gun shooters really want is a caliber that can allow them to stretch their range out well past 150 yards & be less affected by wind, but can still deliver enough force to dispatch a pest or impact a target with authority, without having to aim for the sky in order to hit the target. A lot of long distance shooters love & prefer the .308 caliber for this reason, as well as the .257 The .25 can make it past 150 yards easy, but is somewhat lacking in the power dept at those ranges. The .357 can to, but is a little slow so trying to reach those distances requires a lot more h/o the further you need it to go. The .30 may turn out to be able to provide just be the right combo of weight, velocity, energy retention & wind resistance at longer ranges, depending on pellet/bullet weight & how fast a particular gun can move them.
Some of us just want it all
.30 cal 70 grain BBT @ 900 fps vs squirrel.The real question is would it be enough
Well rkr , we all know once caliber exceeds past .257 shot count goes to pot unless reg'd, & regs defeat the benefits of increasing the caliber. But even if one could only get 10-12 shots on a fill the gains in energy would be a worthwhile trade off to the abundance of shots available from the smaller calibers. You make a good point about the lands, but this is an airgun barrel. They're usually made thinner walled & with more shallow rifling that pb barrels anyway, so I don't think the depth of the lands cutting into the slug would cause too much excessive friction requiring that much more air usage.
Will the .30 be the next .25 ?possibly,.......That is entirely dependent on pellets manufacturers, it's nice to have different powers/calibers to fill gaps, 30-40 FPE .22 - 50-60 FPE .25 - 80-90 FPE .30 - 120-130 FPE .357Than if you wanna go big you have all kinds of options in .357 and .45 to have them in the 100s FPEIt's all about applications, I would like to have a 80-90 FPE .30
