7x57 158 gr GROM from Prvi Partizan - 08/21/08
Has anyone tried this cartridge?
GROM translates to "thunder" as far as I can tell, and the Prvi Partizan web site describes it as a premium bullet: the top half similar to a traditional lead/copper cup and core bullet, with the bottom half solid copper for deep penetration, sort of like the Nosler Partition.
I've tried it in my Ruger M77 tang-safety 7x57, and it shoots as well as the Federal 140gr factory load: right around 1 1/2 inches at 100 yards. I haven't had the opportunity to try it on game, so I thought I'd put this note out there and see if anyone has hunted with it or has tested the bullet in some sort of medium like clay, phone books, etc.
The best part is the price: $11.59 a box from A1 Ammo, $12.99 from Midway. At 2460 fps, it has a point-blank range (+ or - 3 inches) right around 225 yards. This isn't a hotrod load, but it sure looks like it will get the job done.
