7X57 Mauser

[freire]

Hello gentleman.
Today i received in the mail my new to me Brno 21H in 7x57,
i intend to reload using Nosler partitions or accubonds in 160grs.
By any chance any of you reload this cartridge using 160grs, if you do which powder works best for you.
Thanks...Happy new year everybody...

Sorry. I reload everything else, but when I bought my 7x57 earlier this year, it turned out that plain old Federal blue box was a tack-driver. Couldn't possibly better that, so I didn't even try.

Good luck with a fine rifle in a fine round!

In my Brno 22F I use H4350 with 160 grain bullets. Work up to 2600 fps and you will have a very effective "do-all" load.

Hi Victor. I recently worked up a load for my Ruger 7x57. I've been playing with W760 lately, and **grns (max load in my Speer manual #13) shoots nicely. Sub m.o.a. for 3 shot groups with 160 grn Accubonds. I don't have a chrony. My C.O.A.L. is 3.33", which is pretty long. I shoot 120 grn sierras in the same rifle, 3" C.O.A.L. is accurate, but the 160s needed to be seated closer to the lands in my rifle. Have fun!

Congratulations on getting one of the finest 7X57 rifles ever made, Victor.

Any of the 4350s, Re 17 and 19, and both the 4831 powders will all give your good velocity and excellent accuracy with bullets from 140 to 175 grains. I like the Nosler partitions and the Matrix bonded core bullets for hunting. Either one will do you well in 160 grain loads on any game we hunt in North America.

Now, just find one in 9.3X62, and you will be set for any game in the world.
