Thread: School me on the 7x57 mauser

I've had them on and off for the last 27 years. Presently have an R version in a K4. I tend to think of them as the German .308W. Do everything without fuss or fanfare.
I will make a few points relative to handloading. Most 7mm Mauser rifles have very long throats designed around 175 grain projectiles. So having a magazine to seat a pill long in a case is beneficial. You will almost never load 20 thou off. It's (140 - 160 gns) going to jump to the lands.

With respect to JD " With a good rifle design (like a Mauser 98 or any modern action type) with a 24 inch barrel you can load the 140 grain bullet up to 2950-3000 fps and the 160 grain up to 2700-2800fps."
It is not easy to get these velocities handloading and they (his loads) are hot!
He is about 150fps above where most reloaders would say quick and accurate and stop. His results are what you aim for with a 7x64 or .280rem. If you like the challenge of wearing an extractor then WW760 is the best powder for this case. Yes 2209 works but 760 is better, more velocity with less pressure.
However the beauty of the 7 mm is a 140 - 160 works well at safer speeds. (2600 - 2800 fps).

In my experience it is easier to get top velocity (2850 fps) with a 140 in the 7mm08 because the smaller chamber, shorter throat etc.
