What Twist Rate is Best for 300 blackout? 1x7 vs 1x8

When it comes to choosing the twist rate for your 300 Blackout rifle, you may find yourself in a dilemma between 1x7 and 1x8 twist rates. While both options have their benefits, one may be better suited for your needs than the other. In this article, we'll dive into the technicalities of twist rate and discuss which option is best for the 300 Blackout.

Before we get into the specifics of twist rate, let's first understand what it is and why it's important. Twist rate refers to the number of rifling grooves in a barrel and the speed at which they twist. The faster the twist rate, the tighter the bullet will spin as it travels down the barrel. This spin helps stabilize the bullet in flight, resulting in improved accuracy and consistency.

When it comes to the 300 Blackout, there are two primary twist rates to consider: 1x7 and 1x8. The "1" in front of these numbers indicates a single full revolution of the rifling grooves. The "7" or "8" that follows represents the number of inches it takes for the rifling to complete that single revolution.

The general consensus among 300 Blackout shooters is that a twist rate of 1x8 is the better option for most applications. This is because the 300 Blackout is a relatively heavy round that requires a slower twist rate to stabilize it properly. The 1x8 twist rate is capable of handling most bullet weights and lengths and is well suited for lightweight supersonic rounds.

That being said, there are still scenarios where a 1x7 twist rate may be the better option for your 300 Blackout rifle. The 1x7 twist rate is ideal for shooters who prefer subsonic rounds (or heavier rounds) for who plan to use a suppressor. Subsonic rounds require a faster twist rate to stabilize properly, as they lack the velocity of their supersonic counterparts. Additionally, a suppressor can add weight to the barrel, which can affect the trajectory of the bullet. A 1x7 twist rate can help counteract this effect and provide improved accuracy.

Now that we've discussed the technicalities of twist rate, let's talk about where to find high-quality barrels for your 300 Blackout. Moriarti Armaments offers a variety of barrels with different twist rates and lengths to suit your specific needs.
