Hello anyone have the spec's on the .300 win mag, useing 190gr. Serria matchking and Reloader 22 powder all my books leave this combo out, min and max loads would be very helpful.
Thanks in advance.

I used 74 grains on a couple .300 barrels with the 190 Matchkings. You could back that off to 70 to start.

RE 22 and 190MKs are a very popular combo to shoot. Most people find their sweet spot somewhere between 72 and 74 grains, BUT again start around 70 and work up. This worked very well in my Sendero out to 750yds.
