SIG SAUER Rolls Out New 300 Win Mag Match Grade Ammo

Since they stood up their ammunition manufacturing facility a couple years back SIG SAUER has been on a roll. Originally intended to give SIG SAUER the ability to be a one stop shop for guns and ammo for military and government contracts, their ammo manufacturing capacity has given them the ability to provide inexpensive quality ammunition to the masses as well. Their latest addition to the store is a .300 Win Mag cartridge with a 190 grain Sierra MatchKing projectile they claim is “match grade.” It makes perfect sense, since the U.S. military (and just about everyone else) has standardized around .300 WM as their long range precision caliber of choice in recent years replacing the ancient .308 Winchester loading.

Naturally we’ll be asking for some samples to test out. Stay tuned. In the meantime, here’s a press release.

SIG SAUER, Inc. continues to expand its Match Grade Elite Performance Ammunition line for rifles with the addition of 300 Win Mag Open Tip Match (OTM) rounds. Featuring a 190gr Sierra MatchKing® bullet, this new 300 Win Mag load has a muzzle velocity of 2,850 fps and muzzle energy of 3,426 ft-lbs.

Engineered to excel in today’s precision rifles, SIG SAUER Match Grade Elite Performance Ammunition features a temperature-stable propellant that delivers consistent muzzle velocity in all weather conditions. Premium-quality primers ensure minimum velocity variations, and the shell case metallurgy is optimized in the SIG Match Grade OTM cartridge to yield consistent bullet retention round to round. All SIG SAUER rifle ammunition is precision loaded on state-of-the-art equipment that is 100% electromechanically monitored to ensure geometric conformity and charge weight consistency.

“The exceptional quality of our SIG SAUER Match Grade loads makes this line a top choice for professional, competition and recreational shooters alike,” said Dan Powers, president of the SIG SAUER Ammunition Division.

All Elite Performance Ammunition is manufactured in the United States by SIG SAUER to the same exacting standards as the company’s premium pistols and rifles.

    I wonder who’s providing their brass? Good (match) 300wm brass is hard to come by.

    SIG SAUER Rolls Out New 300 Win Mag Match Grade Ammo.

    Why???

    1. avatar Geoff PR says:

      “Why???”

      That’s what I’m asking.

      Intelligent companies ‘Stick to the knitting’, meaning, they focus their efforts on what made them a successful company in the first place.

      An excellent example is Subaru, they primarily make AWD vehicles. (As far as I’m aware, the 2WD models are just missing the AWD bits).

      By focusing on what they do best, they have a much better chance in my opinion of mastering the craft.

      I suppose Sig could, with modern tools (hi-res balances, measuring equipment, whatever the latest ISO standards are) make match grade ammo.

      I’d be more comfortable if Sig sticks to making guns…

        Tell that to sig’s full line of kickass optics. And suppressors. And non standard sig firearms they’ve branched into. If they stuck with what they’ve always done, they’d be much worse off overall. They’ve “mastered” the craft with guns like the 226 legion. If they stuck with those we wouldn’t have the sublime p320 or their high end cans or competition killing optics.

          “Tell that to sig’s full line of kickass optics.”

          Knowing what’s involved with the manufacture of good optics, I will comfortably bet Sig in no way has scope factory where Sig grinds its own glass.

          Upon further reflection, it won’t surprise me if that ammo came from an established ammo manufacturer that just stuck it in a box that says ‘Sig’ on it…

      Some men see things as they are and say why? I dream things that never were and say WTF???

    While the Sierra 190 SMK is a good bullet, I’m more interested in the newer Accubond LR, ELD Match and other bullets that have much better BCs.

    2,850 fps seems kinda slow.

    1. avatar Accur81 says:

      It’s is. A hot .30-06 load can push 180 grainers to the 2850-2900 FPS mark. This looks like another Mk 248 .300 Win Mag military / LE clone load. It’s hot compared to a .308, but not much else in the .300 WM line. It is a consistent, known load though. The 190 SMK has a G1 BC of only .533, and the Accubond LR 190 is .610.

      When people say the 6.5 Creedmoor shoots as flat / more flat than a 300 WM, this is one of the loads they use as a reference point. I haven’t done much load development for my .300 WM other than buying 200 grain ELD-x’s and 180 grain SSTs. At this rate, I’ll have a nice load worked up in the next 5-10 years or so.

      1. avatar Tom in Oregon says:

        Yeah. Different barrels like different loads. Mine just loves the 168 SMK.

  5. avatar Stateisevil says:

    I’ll stick with 195 grain EOL berger. Same speed but with .755 BC. And less recoil in 7mm mag. Not as much brass options in 300 either. 300 wm in 230 grain berger good though.

  6. avatar Dan l says:

    Ya thats a state of the art load for the 300 straight out of the 70s. U need a 208 amax at minimum, bergers are best. And sadly nosler is very optimistic about there bcs. There 20% higher on the label on average than what they are in the real world. Google it and check out the research by bryan litz…. if you like shooting far you might wanna buy his books.

    I bet cost will be low. I got some sig sauer labeled 300bo from psa for 12 a box, not bad with 220 seirras. This loadwould be great at 20 to 25 a box.

    If u think sig makes great scopes your wrong on two accounts. First they dont make them. Second ive read nothing but bad reports and quality problems, so much so that the tango 4s and tango 6s were taken off the market.

    They make done decent 10mm not super hot but not 40sw either
