Before the introduction of the Winchester’s .350 Legend barrel, there was already a pool of tested and trusted calibers available on the market. In the midwestern parts of the United States such as Iowa, Ohio, and Michigan, the use of traditional bottleneck cartridges posed a problem. Since traditional bottleneck cartridges tend to produce higher velocities, it became a concern to those areas with smaller hunting grounds. 

For that reason, several states limited the use of firearms to muzzleloaders and shotguns. But after a while, other states loosened their restrictions by only allowing the use of straight-walled cartridges for hunting. That’s when the .450 Bushmaster increased in demand. It became the king of straight-walled calibers. However, even though it’s a great round for hunting, it’s expensive and has a lot of recoil.

So, Winchester Repeating Arms saw an opportunity to develop a new cartridge. This led to the innovation of the .350 Legend. Winchester claims that it’s the fastest production straight-walled hunting cartridge in the world. It can deliver enough energy to produce lethal effects on a large deer at an effective range of 250 yards — which is astounding. It’s an ideal choice for hunting in areas with ammo restrictions.

These are the barrels we’re going to review:

  • Faxon Gunner Profile AR-15 .350 Legend Barrel: A highly accurate barrel with the ideal balance of a government and pencil profile
  • CMMG .350 Legend AR-15 Barrel: Barrel made of chrome moly steel with great accuracy
  • Shaw .350 Legend Barrel: A barrel made of polished stainless steel that gives a tactical look
  • AR-Stoner .350 Legend Barrel: A barrel made of polished stainless steel that gives a tactical look

First, we’ll look a bit closer at the characteristics of this cartridge before we get into the pros and cons of our top four barrel picks.

The .350 Legend vs. .450 Bushmaster

In this ballistics test by Great Days Outdoors, they compared the performance of the .450 and .350 cartridges.

Using the larger .450 with a 250gr bullet, the .450 delivered 2,200 fps of muzzle velocity and 2,675 ft-lbs of energy. It dropped 4 to 5 inches between 100 – 200 yards.

In comparison, the .350 Legend, using a 150gr bullet, delivered 2,300 fps of muzzle velocity with 1,800 ft-lbs of energy. Although it does not have much power as the .450, the .350 Legend offers many impressive characteristics. Firstly, the bullet drop of the .350 is slower. Secondly, the caliber creates less noise. Thirdly, the 350 has less recoil, making it ideal for small-framed and young shooters. And fourth, it has a lower price point. If you shoot a lot, you will save a significant amount of money.

What’s the Best Barrel Length for a .350 Legend?

Only you can answer this question because the best .350 Legend barrel will always depend on your personal preference. However, for what it is worth, my choice for an ideal barrel length is 20 inches. I find using a 20-inch barrel viable for hunting large animals. A longer barrel can deliver higher velocity and accuracy. This is demonstrated below, with the “velocity by the inch” test.

Firearm Convention used a barrel with an initial 25-inch length. After firing a total of 5 rounds, they cut off 1 inch. This was repeated until they were left with a 7-inch barrel. The table below shows the average velocity of the 5-round shoot for each barrel length.

As the results above show, a longer barrel delivers higher velocity. Now, let’s talk about the best .350 Legend Barrels in the market.
