SigSauer Ammo

In case you haven’t noticed, SigSauer is becoming a real player in the ammunition field. Like so many companies with European origins that go back centuries, the current American-based SigSauer, Inc. represents the Swiss firm, SIG, and the German firm, J.P. Sauer, both of whom have a long history of firearms manufacturing.

In 1976 the two became sister companies under one ownership and in 1985 established a subsidiary company, Sigarms, here in the States, to import the products of both companies. After a restructuring, SigSauer, Inc. was established in 2007 with headquarters in Newington, NH.

Since that time the company has become surprisingly diverse, for in addition to manufacturing world renown pistols, bolt-action and AR-platform rifles, they also produce riflescopes, electro-optics, airguns, suppressors and conduct a 200-acre firearms training facility in Epping, NH.

But the company’s fastest growing business is in ammunition, which is now being manufactured in its brand new 70,000 sq. ft. facility in Jacksonville, Arkansas. In just six short years the company’s SigSauer product line has grown to where they currently offer 44 centerfire rifle and 61 pistol loads. Among those offerings are three in 6.5 Creedmoor.

Now it just so happened I had a Shaw Barrels’ Mark X Chassis rifle in 6.5 Creed that I was about to review for a second time. Normally, I use at least four different factory loads of different manufacturer when bench testing a rifle, but in this case I had a couple boxes each of all three of the SigSauer loads on hand and thought it would be an interesting test of both rifle and ammo, particularly because there were three bullet weights represented — 120, 130 and 140.

The test gun is an imposing piece of ordnance consisting of Shaw’s own Mark X action mated to a 24” Heavy Varmint spiral-fluted barrel set into an MTD chassis affixed to a Magpul PRS Gen 3 adjustable buttstock. With a Leica 4-20×50 scope aboard, the range-ready rig weighed just two ounces shy of 13 lbs. Hardly a hunting rifle, but obviously that’s not what this rig was designed for!

The range results below pretty much reflect what I’ve learned over the last couple of years — that SigSauer is producing some very good ammo. Now granted, the test rifle also has to be very accurate, but then a gun is only as good as the ammo put through it. I’ve not yet had the opportunity to use any of their ammo on game, but the accuracy is certainly there! The addition of several new calibers and loads are planned for next year.

I should point out that SigSauer offers unprimed brass from .223/5.56 to .338 Norma, and .380 to .45 Auto. To find out more, visit their website at –Jon Sundra
