Except it can't because it hasn't been met with standardization, there are no mainstream guns for it and no mainstream ammo. It's a specialty thing that is heavily reliant on conversions for the public . it's not a a buy a gun and a box of ammo and go type of thing. While 10mm isn't super common, it's way more available than the Rowland will ever be . why? I don't know but it may have something to do with the question of - what will the 460 Rowland do that a 10mm can't ? More power, yes but it won't match a 44 magnum and 44 mag is the smallest of the big magnums currently available . 10mm has its hands full trying to match 357 mag but it's comparable. With the 10mm you get flatter trajectory than the 45 acp , other than that it's not much advantage. If there was a 460 Rowland that could feed wfn bullets I could say there's something there until then the big revolvers will dominate the 460 in everything I can do. Big bullets do fine at low velocity and it's something that can't quantified on paper, a 250-300 grain bullet @ 1100 is formidable, way better if the bullet profile is better than a RN - seems the 460 will be stuck with profiles that work in semi autos , it'll need to work much harder to match what a lower pressure and more pleasant cartridge can do because of the projectiles will be.I think the point of this round is that whatever a 10mm can do, the 460 can do better.
Neither has 9 Major.Except it can't because it hasn't been met with standardization
So is the 9mm Major but it's seems to be doing fine. Even some commercial companies making ammo for it now.there are no mainstream guns for it and no mainstream ammo. It's a specialty thing that is heavily reliant on conversions for the public

Did a very similar conversion on a XD45 tac.I went with a Glock 21 gen 3 with a a KKM threaded barrel and a screw on slab sided 3 chamber comp and a heavy 24 pound recoil spring. I too cast 255 grain .45 Colt bullets sized to .452 and load them to around 1100 fps. I also take off the com and put the standard recoil system back in for suppressor use (it has tall big dot sights) so it is very veratile. I do use only Starline .45 Super brass and have no trouble with the beast running at the 1100 fps range withe 255 bullet. However , both my son and I have gone the 10mm route as our bear protection guns with a Glock 20 and a Sig 320xten , as it is easier and with reduced recoil springs seem fine with our .40S&W loads for "plinking".
