I have a Mexican small ring Mauser that my dad built with a new 20" Douglas barrel, really nice wood, Timney trigger and new bolt handle. He chambered it in 7mm-08. Is it possible to re-chamber to the more classic 7x57 without needing a new barrel? I know both rounds are very close from a ballistic standpoint, and I already have a Sako 75 in 7mm-08,but it just seems that this rifle would have so much more "cool factor" in 7x57.
Thanks in advance.

I doubt it, you would be better of going to 7x64 or 280, or just leave it as it is.
These are my opinions, feel free to disagree.

You'd have to set the barrel back about 0.25" to get rid of the 7-08 shoulder area, but otherwise, you're fine. Without the setback, you'd have a double shoulder.

I'm guessing the twist on that barrel is not 8.75", which is the standard for 7x57, and a superbly useful twist at that. Is that right?

There is nothing to gain in going to the 7/08 other than headaches.If you set the barrel back to clean up the chamber you will likely have to 're-inlet the barrel channel.The small ring action is perfect for the 7x57. Leave it alone.
You can fool all the people some of the time and some of the people all the time, but you cannot fool all the people all the time.

"my dad built" This would be enough to make me leave as is, my dad gave me his old 303 he has had all his life, he sporterized it, shortened the barrel himself, recrowned it himself, and worked the stock down and added a higher comb, I would never think of changing it, he is 90 and still around.

Both rounds are excellent.

Why waste a lot of money and screw up a good rifle just to end up with pretty much what you had when you started?

Partsman - agree, but I have quite a few that he built, including ones he built for my 2 daughters on Mauser actions - 257 Roberts and a 6.5x55.
He tends to like the classic rounds, and I'm not sure why he didn't make this one a 7x57, so was just checking to see what it would take. I'll probably just leave it as is and work on it feeding - the sharper shoulder of the 7-08 creates some issues.

just rebarrel to 7x57 if this is really what you want , but since your dad gave it to you and if it groups well then i would leave as is and build a 7x57 on another rifle or action.

... the sharper shoulder of the 7-08 creates some issues. Trash that barrel and get another chambered for 7x57, twisted properly. I have some things of my Dad's that I feel sentimental about, but to be quite honest, not all of his projects were good ideas.

I find nothing special about the old 7-57.
Sure somebody shot elephants and sold their teeth long ago but otherwise the ammo is not available easily as it never was popular here in the USA.

Man, you are consistent!
A few years ago I decided to try some factory 7x57's out, to see how they compared to 7mm-08 factories, since people keep saying how 7x57's are loaded down so much. I tried one local store here in Montana and found three brands of 7x57, equally the variety of 7mm-08 ammo on hand. (Turned out the 7x57 stuff was a whole 100 fps behind the 7mm-08, on average.)
I would bet serious money that you'd find more 7x57 ammo on gun store shelves in most parts of American than ammo for the .358 Winchester, the cartridge you keep holding up as ideal.

That sounds like a vote FOR the 7x57... DF

I'd also lay pretty good odds on Beck's not having any .358's.
