I don't know what is worse: Resurecting a two month old thread or starting a new one that covers "the same ol' thing". I flipped a coin and here I am adding to this thread.
Today I gathered up a few different blends of ammo to test for my OBR (can't afford to keep shooting Federal GMM). I have Hirtenberger on my to-do list but have not ordered any up yet. Anyway here is my mini report for my Sunday afternoon fun shooting 100 rounds of each of the following "budget" fodder.
BOWN BEAR (Russia) 145gr Bimetal FMJ Lacquered Steel Case $.40/rnd ..... Average 10 round group 2.75" (10 groups)
SILVER BEAR (Russia) 145gr Bimetal FMJ Zinc Plated Steel Case $.42/rnd .. Average 10 round group 3.25" (10 groups)
AMERICAN TACTICAL (Turkiye) 150gr FMJ Brass Case NATO Spec $.49/rnd .. Average 10 round group 1.25" (10 groups)
Control Group:
FEDERAL GOLD MEDAL MATCH 168gr BTHP $1.30/rnd ... One 10 round group 0.51"
All rounds were shot prone at 100 yards, 74 degrees, null wind. I shot 10 rounds of each type of ammo in succession and rotated each type thru 5 magazines in order to mix things up as much as I could. I had one Failure to Eject on the first volley of Silver Bear and one bad primer on the 7th round of the fourth volley of Brown Bear. Other than that there were no problems as the OBR digested them all without fail.
After shooting all 310 rounds (no cleaning) I found no lacquer build up from the Brown Bear. The low round count may be the reason but I have read other reports that say the melting lacquer problem has been solved.
The Silver Bear left very noticeable amounts of zinc shavings on the bolt face and locking lugs. If I had to pick between the Russian ammo I would go with Brown Bear but I would keep an eye out for lacquer build up just in case those reports I read were incorrect. The Silver Bear leaves too much zinc shavings in the weapon for my taste
(and, for me, it was less accurate even though it was the more expensive of the two).
Of the the types of ammo I shot today I would lean towards the American Tactical because of the brass case and considerably better accuracy (although FAR from FGMM!). I would feel okay using it to tune up fundamentals and for move-and-shoot drills. I would, however, defer back to FGMM or home brews for hunting or competitions.
The OBR defintely needs a cleaning after today's fun but I would have to shoot numerous rounds each type on their own to determine which of the three were the major culprits. Based on what I've read in other reviews I would have to guess it was the Russian fodder that was responsible for most of it.
Good Shootin'
