Reloading The 7mm (7x57) Mauser Rifle


(Note: These are maximum loads, you should use 10% less to start.)
(See note on Powders below or read all about various Powders.)
Bullet is .284" diameter. These loads are for the stronger Model 98 Mauser and other modern rifles. DO NOT use in the older Model 93 or 95. You would have to reduce the load for them. I do not have load data for older Mausers. Because of type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

Discussion: This cartridge has been around in Mauser rifles since the 1890's. It was used by the Spanish military originally and later in Mexico and other Spanish American countries. Some U.S. rifle makers have chambered for the 7mm over the years. This caliber (essientally at 28 caliber) in the stronger 98 actions (and other modern rifles) can move lighter bullets right at 3,000 fps and the heavier 175 grain hunting bullets near 2,500 fps. This makes a decent hunting rifle for deer and slightly larger game.

Over the the years, Rememington chambered several rifles in "7mm-08" . This is a .308 case necked down to take a 7mm bullet. It can move a 7mm 175 grain bullet to the same speeds as the original 7mm Mauser, but in a shorter case.
