I haven't looked elsewhere, but Match Grade Machine evidently only makes .357 Maximum barrels from blanks with a .358" groove diameter. All my manuals specify .357" as the bullet diameter. How concerned should I really be about this? I wasn't really planning to load with rifle bullets.

Howdy !

IF your chamber could accomodate a .357Max round that was actually loaded w/ a .358" cal rifle bullet, could you go that route' ? I do realize that bullet wt / selection for the 'Max might be biased towards 180s and less.
I say this because I had a custom SS .358" calibre rifle barrel chambered for .357 AutoMag..... but I shot .358" cal rifle bullets ( " .358AutoMag " ).
For my shooting application, I wanted hyper accuracy in a .358" cal cartridge. I at first shot Rem 150 PSPs and they were fantastically accurate...... but I ran out of my bag of 500.
I then switched to the incredible Cutting Edge .358" cal turned-brass 150gr Extended Range " Raptor " bullet.
I klled groundhogs w/ the set-up out to 350yd ( the farthest shot I got to make using the rifle ).
I believe my barrel had 1-16 twist. The best charge ended up being 24gr WW296 and SP Mag primer.
That is something in the .357Max zone.
The 150gr brass " Raptors " are ong for their wt, but the barrel twist stabilized them just fine @ the charge wt mentioned.
With regards,
357Mag
Cutting Edge also makes a 160gr copper version, and some handgun cal offerings.
