The RWA HM1000X .30 caliber barrel is a Lothar-Walther polygon barrel. IF I decide to size/resixe pellets would you recommend a 7.62 or a 7.63 resizer? I have the TRROBB tapered resizer for my .25 cal but he doesn't make one for .30 caliber. Looks like the only .30 caliber resizers make the head and pellet skirt the same size. Doesn't seem right...any problems with this from those who have used one?

Someone posted a company that makes nonadjustable individual tapered sizers a few days ago, I don't have a link to it but I think they might have what you want.

If not mistaken Air Gun spec .30 cal are .300" where as .308 cal fire arm is classified at a 7.62 metric

But said measuring a .308 bullet is larger than a .300 AG slug .... somethings lost in translation between Fire arm and Air Gun barrel spec/sizing ? being likely a Land / groove spec difference having a Firearm barrel having a deeper groove and larger diameter tho still being .300 diameter on the Lands.

I asked them about it and that's why I made this post. They said "You will have to figure out the size you will need each barrel is different." So - no help at all.

I don't see the poly .30 listed on LW website for spec. but the 28" 6g no- choke .30 is .298 x .306 16 twist .There is only .00039 difference between the 2 die sets You can measure your bore with pin gauges from amazon then measure groove with a .306 slug pushed thru mic that. Id by em both because no way to know which it will like with pellets. .300 vs .30039
