The 7x57 doesn't have a lot on a .270, but the common availability and use of 160 and 175 grain bullets make it a better rounded caliber for larger game. Besides it's just a lot more in the nostalgia department, the .270 will never be a 7x57.

My 7x57 is not as pretty as those listed being built on a large ring mauser action that strangely has a action like that of a small ring mauser. I put a stainless barrel on it and painted the action and barrel with grey galvanizing compound and painfully fitted it into a Ramline synthetic stock built for a small ring action. When it finally started shooting like it should I patch painted it with the same paint, UGLY! I cut the barrel from 24 inches to 19 just to ease handling in tight places. This is my lousy weather rifle and I am perfectly happy with 2300-2600 feet per second loads with 160 and 175 grain bullets. Why push velocity in a rifle that will never be used at any range farther than 250 yards? I have a 270 for that and bullet performance with Sierra and Hornady standard style bullets is perfect. The only thing I would change is the Ramline stock but as is it will do anything I need done in the eastern half of Texas.

Bob,
I have a 7x57 Mauser 98 project at the moment and I have bought a 24" Heym semiweight barrel. I installed a front and rear sight. The original mauser 3-position safety I changed to a Dakota safety.
I shoot also the 7x57 in a Spanish service rifle (M98 1910) for military shooting. The accuracy at 100m is very good.
I�m loading the 154grs SP Hornady and the 160grs SP Speer bullet.
