I found the 460 cases in the 460 revolver expand quite a bit. When resizing, particularly the last quarter inch to half inch of the case is a considerable squeeze On the case after heavy 325 grain lead cast bullets are shot. I leave the last 6.0 in an inch of the base of the case alone, as I found it unnecessary to resize the tail end of the case as it re-chambers wonderfully . It doesn’t seem to be excessive but... Anybody else find this to be the case or do I just have an extremely large chamber in my revolver?

I just fully size them, but it seems to me that I came across this before. Other than ease of resizing, there may have been another benefit, but what it may have been I cannot recall. Other more experienced will likely chime in.

Only 'situation' I have is cracking case mouths (Starline Brass). I actually anneal the case mouths now because of the very aggressive crimp I apply. Never had an issue with the brass expansion near the base of the case.

Thank you for the response guys.
I believe these cases in particular were over powered in that the lead was soft on these rounds and when I lit them off, I though the gun was going to explode. (perhaps the lead was causing excess pressures as it filled the entire barrel up with lead when I looked down it after range time was done)
Getting hit in the face from particles coming from the hand gun, is a bit frightful, especially when I shot off some full loaded 454 cassul speer 300grain deep curls and they were sharp kicks but no spraying of parts in my face going on.... and were fun to shoot.. I was a bit worried, after the cases required a bit of force and needed lube, otherwise the resizing die would want to shave of some of the brass casing.

My later loads with the same:Lyman 325grain lead mold, using Linotype lead.and they didn't spit anything out the ports and my barrel had NO LEAD in it... unlike the previous molds, that leaded up the entire barrel, from start to finish... (took better part of 2hours to get it all out of the cyl. and the barrel)
These cases didn't require the same amount of force to full size, but latter realized I didn't need to full size them anyway.

I learned the hard way about annealing.. Got the tips of around 300+ casses of 44 mag too hot, and the case mouths never stiffened up (can crush it easily by pressing it on the counter top)
There is some really bad youtube videos that steered me the wrong way about it... You DO NOT want to get them red on the tips.... not good results but I was wanting to do something as the cases were cracking, as my dad had loaded them up 10years + prior and out of 100, 5 or so would crack half way down the case.
But hey... the softened cases never cracked again!...😁
I will use them in my lever gun and leave them at the range, after doing some cowboy action shootn.. as they have worked fine with lighter loads.. the Hot loads causes the cases to overexpand, and the case of course doesn't rebound like brass should and then stick in the lever gun, and require a very stern clack of the lever... interesting enough, the short 44 mag handgun, obviously doesn't increase the pressures like the longer barrel in the lever gun, and they extract w/o issues in the wheel gun even with full loads.

Livn learn... I guess..

Use Templac. I do. I use an Annealeze in a darkened room so I can observe the case color. All you want is a slight dull red, nothing more and a properly annealed case will appear purple after it cools.

Toss the over annealed cases, they are dangerous,

460 cases solved....
I know threads worthless without pictures but Hodgdon website shows upwards of 41 grains of H1 10 and that’s just too hot in this gun put it down about 37 grains and no more case issues ( and what do you know)
The primer’s do not look like they were smashed by a 10ton press.
Lyman manual states 25grains maxh110. I really don’t understand the discrepancy between the two but I’ll see Hodgdon‘s website it is over what it should be it’s just too damn hot and just almost smashes the walls of the cases and the primers I have to show pictures because it’s a ridiculous what I was doing to them.

I realize that there’s a lot of variables but I think I need to purchase a chrono especially when dealing with such pressures in a hand gun.
it will tip me off when things are not right.
The accuracy seems good as well, will have to do more tests with accuracy.
My phone camera does not work but will have some phots in future

A couple of points about the 460S&W that I've experienced myself, and that I've read here and on the blue forum. I almost always get flattened primers with most every powder I've used, but especially with H110. One of the great things about using H110 is that it's almost impossible to overcharge a load with it, and sticky cases won't happen with light bullets. It's pretty safe to use in the 460S&W. You might need to go a little under a full load for heavies to prevent sticky cases. You mentioned several maximum load values, but not bullet weights so it's difficult to provide more help. I'm sure SidecarFlip may have some insight to share.

I've shot a 320gr MBC cast PC with max load of 2400, and had no unusual case expansion issues. The 460S&W case does normally take a good amount of force to resize because it is so long. I'll be loading up this projectile with H110 up to max next, so I'll pay attention to the expansion and post anything unusual.

My recent issues have been leading. And yes... it is massive leading....
The 330gr. Gas checked lead 460 lead bullets can easily hit a quarter at 20yards but bring out the 454 Cassul 250gr lead bullets and lead up the barrel and the accuracy goes to hell.
Clean out the barrel, shoot jacketed bullets or gas checked lead an accuracy galore.
Background: The cylinders are perfect, in that they are all cncd, cut now, and there is little to NO variance with these modern machined cyl on this 460. The bullets fit through with w/o swaging the rounds , and YES I can swage out CHUNKS of shiny lead out of the barrel, so I have with out a doubt it is leading...
This ONLY occurs with bullets that 1. Are LEAD bullets ( powder coated HI TECH. from A manufacture or my own lead bullets with lube) The lead bullets are 12-15 Hardness. The leading DOES NOT occur when I have a GAS CHECK or when they are copper coated.
Chrono places the 255gr. bullets at 1,110 to 1,300. is a SWC.Keith.shape.
Tried 2 dif. powders and same issue ( at min charge). I also add....This leading is occurring with 454 Casull cases.
All bullets were 45.2 (lead, Hitech coated, and brass plated) so all else being equal.
Tried Universal and Titegroup with equal leading occurring.
The forcing cone is also generous w/o any swaging of bullet.
Will be trying some lower speed cowboy loads in the 460, and 454 cassul cases and trail boss powder, and 250 grn S.W. E. Kieth.
My phone is getting new parts, so hopefully will show some picts....

Interesting. I get some noticeable leading with Hi-Tek cast projectiles, but it shoots right out with plated or FMJs. Notice I said "noticeable leading", not a fouled up barrel. I'm shooting only fast 460S&W, not 454 or 45C.

Don'r shoot any lead pills, only gilding jackets. Hornady and Swift.
