New: Winchester 350 Legend Cartridge

By Dave Dolbee published on in Ammunition, News, Videos

The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), the firearms and ammunition industry’s technical standards-setting organization, is pleased to announce the acceptance of a new cartridge and chamber standard, the 350 Legend (350 LGND), introduced by Winchester Ammunition.

“SAAMI member ammunition and firearm companies are driven by technological innovation.” said Randy Bimson, Director of Technical Affairs and Technical Advisor of SAAMI. “Winchester’s 350 Legend cartridge brings a fresh look and innovation to a very mature cartridge category opening up new options to both the hunter and recreational shooter. SAAMI is pleased to include the new 350 Legend in the SAAMI standards.”

Winchester Ammunition is addressing a rapidly growing market segment, “straight-wall-cartridge-compliant” deer-hunting states. A growing number of states that previously restricted deer hunting to limited-range slug guns or muzzle loading firearms are now allowing rifles chambered in straight-walled centerfire cartridges, many of which originated as handgun cartridge designs. The Winchester 350 Legend offers a significantly flatter trajectory and better terminal performance over current straight-wall cartridges while remaining compliant in most applicable states.

“The 350 Legend is a high-performing, straight-walled cartridge that dominates in velocity, energy, recoil, and affordability, all of which are vital to our customers,” said Matt Campbell, vice president of sales and marketing for Winchester Ammunition. “Winchester is dedicated to innovation and it’s paramount that we continue to deliver meaningful, technology driven products that have a tremendous impact on the hunting and shooting sports industry.”

More information about the current 350 Legend offerings can be found here.

The SAAMI cartridge and chamber drawings and velocity and pressure are available here.

SAAMI was founded in 1926 at the request of the federal government and tasked with coordinating the industry’s technical data, creating and publishing industry standards for interchangeability, reliability, performance, quality and product safety, and promote safe and responsible use of firearms.

    Looks like a .351 WSL “Magnum” to me. why not just re-introduce the classic .351 WSL with modern loads? This perceived need to re-invent the wheel by the firearms industry escapes me.

    So, at the risk of sounding like a moron, why are some states limiting to straight wall cartridges? My state doesn’t and I couldn’t find any good info on it in a quick search.
    Thanks,

    Disagree. Cartridge and chamber specs were included in the link. I suspect that current ammo specs were in the other link. (Click the link, pdf file automatically doenloads, how hard is that?)

    How is this good-looking round different from the 357 Max Rimless?

    So it seems like a straightwall 35 rem with a rebated rim? 357 max is a great 35 cal straightwall cartridge and probably has similar ballistics in a rifle if loaded properly. I can’t say that for sure because actual ballistics are not currently availablle. What is OAL? Can it be used in an AR platform? I hope so, I have been waiting for a factory developed 35 cal AR platform cartridge. Will bullets be available in 140, 180g, 200g and 250g from FTX to cast core and Bow tail designs?

      Looking at the saami specs, yes it would fit in an ar 15 platform.

    Other than lower recoil, I don’t see much advantage over the 450 Bushmaster, and I don’t find the recoil on the 450 to be offensive.

    I would be interested in how the trajectory of the 350 compares to the 450 out to about 300 yards.

    I like you articles most of the time. However this was a waist of good space and more advertisement than good imformation. No specs or actual photos or range imformation on its loadings current or planned. Most of us not all are very aware of SAAMI and their function. More like teaser. It really waisted good internet time.

    Stick with my 45.70 i do not see the need for this when so many straight wall’s are out there do a better job to me .But i would love to try one at the range before making a final decision on just how much this even matters .

      This 350 legend round seems to fill the need for a “girl gun” cartridge… for my money the 45/70 is the way to go … guess since more ladies are hunting these days Winchester stepped up with this new 350 legend round ?
