What's the Best Grain for 300 Blackout Loads?

Ammunition & Reloading
1

I’ve been diving into the world of 300 Blackout ammunition, and I’m eager to hear your thoughts on what the best bullet grain is for different purposes. I’ve read various opinions and reviews, but I’m still a bit confused on the optimal choices for specific applications.

Hunting

When it comes to hunting, I’ve seen some people swear by 110 grains for deer or hogs, while others advocate for heavier grains like 125 or even 150. What have your experiences been? Is there a particular grain that performs better in terms of stopping power and accuracy?

Target Shooting

For target shooting, I’ve heard that lighter bullets, like 90 or 115 grains, can be more accurate at shorter ranges. But if you’ve got a preferred load for plinking at the range, I’d love to know what you use and why.

Overall Recommendations

Also, has anyone experimented with subsonic rounds? I assume there’s a different grain range there, and I’d appreciate any insight into how they stack up against supersonic rounds, both in performance and cost.

Considerations

  • Are there specific brands that you find more reliable?
  • What about reloading? Is there a particular grain that is easier to work with or produces better results?

I’m keen to gather all your advice and personal experiences. Let’s help each other out in finding the best grains for our 300 Blackout setups!

I’ve found that 110 grain bullets provide excellent accuracy in my .300 Blackout loads. They really shine in short barrels and are great for close-range shooting.

Totally agree! I prefer 125 grain for a bit more velocity. It’s a great balance between speed and stability.

I’ve also had good experiences with 220 grain subs. They offer superb suppression with my suppressor and I can hit bullseyes easily at 100 yards.

What kind of suppressor are you using? I’m curious because I’ve been looking into quieter options.

I’ve been using the SilencerCo Omega 9K with my 220 grains, and it’s incredibly quiet. Definitely enhances the accuracy during shooting sessions.

For those who want to focus on home defense, I recommend 130 grain. They hit hard but still maintain manageable recoil and accuracy.

That’s a solid choice! My wife feels more confident with the 125 grain, which is also lighter for her to handle.

Has anyone tried the 150 grain bullets? I’m curious if they provide better accuracy compared to the lighter options.

10

In my experience, 150 grain can be less consistent in accuracy—especially in shorter barrels. Stick with lighter grains for better precision.

11

LOL, I thought the heavier the grain, the better! Guess I need to do my homework. Thanks for the insight, everyone!

12

You’d think, right? But often it’s about finding the right balance between grain weight and your specific setup. It’s a bit of trial and error.

13

Great point! I’ve seen hollow points perform better in terms of terminal ballistics, especially at close range, but they can vary in accuracy.

14

What about the effect of different bullet designs (like hollow point vs. full metal jacket) on accuracy? Anyone have experiences to share?

Thanks for that insight! I guess it’s always a balancing act with ammunition type and purpose.

I’ve had great success with 220 grain subsonic loads for suppressed shooting. The noise reduction is fantastic, and it cycles smoothly in my setup.

17

I’ve heard a lot about 220 grain! What specific brand do you recommend? My buddy told me to check out Hornady.

I’ve been using the 208 grain A-MAX. It’s also quiet and maintains good accuracy. Plus, it expands well on impact!

A-MAX is a solid choice! I’ve seen some impressive groups at the range. How is it for cycling in semi-autos?

I’ve had feed issues with 208 grain in an AR-15. The 220 grain works much better for my setup, especially for suppressed use. Just my experience!
