Introduction

If you’re venturing into handloading for the .300 Blackout and considering H110 powder, you’re in good company! Many reloaders have found success using H110 for this versatile cartridge. In this post, we’ll discuss some effective load data, performance insights, and tips to get the most out of your .300 BLK loads.

Why Choose H110?

H110 is a popular choice for .300 BLK due to its consistent performance and velocity with both subsonic and supersonic loads. Here are a few reasons why you might consider H110:

  • High Energy Density: H110 provides considerable power in a small charge, making it ideal for compact cartridges like the .300 BLK.
  • Temperature Stability: It has good temperature stability, which can help maintain consistent performance across different shooting conditions.
  • Wide Burn Rate Range: H110 works well with a variety of bullet weights, from light to heavy, allowing versatility in your loads.

Basic Load Data

Here are some recommended load recipes for the .300 Blackout using H110 powder. Always remember to start low and work your way up to ensure safety and performance:

Tips for Success

  • Measure Twice: Always double-check your measurements for powder and bullet seating depth. Consistency is key to accuracy.
  • Chronograph Your Loads: Using a chronograph can help you monitor your velocities and ensure your loads are performing as expected.
  • Document Everything: Keep a detailed log of your loads, including components, charge weights, and performance results. This will help refine your loads over time.

That’s absolutely right! The ability to use it with a suppressor is a game changer for me. I’ve found it to be fantastic for home defense as well.

I’ve seen folks debate whether .300 BLK is better than other calibers. Its design really sets it apart for close-quarters situations. The low recoil and high energy dump can be great for new shooters too.

Totally agree with you! It’s super effective in hunting too. I’ve taken deer with it without any issue!

For those new to the .300 BLK, understanding its ballistics helps a lot. It’s designed for short-barreled rifles, and the round performs excellently out to 200 yards, which is achievable for most situations.

Using H110 can lead to some really great results, but it can also be tricky. You’ll want to start low and work your way up while keeping safety in mind. I love it for its consistent performance!

In my experience, the .300 BLK shines in subsonic loads, especially for tactical use. Always have a good load bench setup to tweak and test! Anyone else have tips on favorite recipes with H110?

10

I’m curious too! I usually use 190-grain bullets with H110; they really pack a punch! Is there a preferred bullet weight for subsonic loads?

11

For subsonic loads, going heavier like 220-grain can be effective. Just watch out for overpressure signs if you’re pushing toward the limits! Anyone tried that combo?

I’ve had great success with 125 grain bullets using H110. They seem to be a sweet spot for reliability and velocity! What are you thinking of using?

17

I also prefer 125 grain bullets, especially for hunting. I typically get around 2,150 fps with my loads. Make sure to start low and work your way up.

18

Why not 150 grains? I’ve heard they can be quite effective too, just wondering if anyone has experience with that weight.

I tested 150 grains once, but I found H110 didn’t perform as well for me. I got better groups with the 125s. But hey, if it works for you, go for it! Everyone’s setup is different.

Absolutely! Personal preferences play such a huge role. What powder did you switch to for the 150s?
