I'm testing all of my 300BLK rifles with my collection of supersonic ammo to see how accurate they are. Last range report I tested my Sig MCX + CAT RAT Flow. This time, I'm testing my Radian Model 1 in 300BLK + CAT ODB.

The rifle:

• Radian Model 1 9" 300BLK upper on a milspec lower
• CAT ODB Inconel Hub
• AI Nano muzzle device
• CAT TSF-X Hub Adapter

Additional setup used for bench testing

• Leupold MK5 HD 3.6–18x scope
• Shooting bags:
  • Caldwell Deadshot front shooting bag
  • Armagedon Gear X-Wing Large Enhanced Rear Shooting Bag
• Garmin Xero C1 Pro chronograph
• MantisX X10 Elite to record firearm movement during each shot

I tested 7 different supersonic 300BLK ammunition. For each one, I shot two 10-shot groups at 50 yards. The table below is a summary of the results:

The mean radius column and the extreme spread is the average of the two 10-shot groups for each ammo. The rest of the columns are simply based on all 20 shots. I list mean radius first since I think it does a better job than extreme spread of summarizing precision. Extreme spread is decided by only two shots, and is more noisy. Same exact principle applies to the standard deviation and extreme spread of muzzle velocity.

Overall, I was relatively impressed with the precision of the Radian Model 1. One of the Black Hills TMK 10-shot groups was 1.1 MOA. The other group was also close to being a ~1 MOA group, but shot #1 was a flier, making that 10-shot group 2 MOA. Looking at the MantisX and the Garmin data, nothing was off, so it appears to be a valid shot. Regardless, very good performance overall.

Phantom Defense "Spicy Boi" 85 grain was disappointing. With a mean radius of 1.22 MOA, it had lower overall precision than my bulk ammo, Magtech 123gr. It performed on the low end in my Sig MCX precision test as well. Due to its low ballistic coefficient, Phantom Defense 85gr is geared for closer engagements, so its lack of precision is perhaps less important.

Phantom Defense TAC-TX 110gr performed very well. Great accuracy and high muzzle velocity and energy. And this bullet is a known strong performer. This is definitely the ammo I will use as a defense load for this rifle + suppressor.

I've been trying to find a good home for this 8":300BLK upper that I built recently and I think I found a winner. I'm waiting for my light to come so I can use this for home defense. This is what I came up with since my last post. My next post will be about the light I got. I'm keeping the light a surprise. I'll be very interested in what the community thinks. Untill thén I hope you enjoy this pic.

What’s is everybody using for a supersonic deer hunting projectile. I feel like the obvious answer is the Barnes TAC-TX line of bullets but as far as lead based what are people using? Seems like 110 v-max, 125 SST, 125 nosler ballistic tip are pretty common?

Specifics of the rifle is a CVA scout with 16 inch barrel shots out to 200 yards.

Thanks for any input!

I know this has been discussed quite a bit, but can’t seem to get clarity on this particular situation…
Trying to help my dad find a can for his Geissele SD 8” 300 w/ phased array, but i have very little suppressor experience (non friendly state). It’s a full Geissele build. He said it came with an H1 buffer. Wants to shoot subs 90% of the time, and wants a balance between sound mitigation and not too much gas blowback. Should he be looking at low, medium or high back pressure cans with this system? It came with the Hux flash hider, making me think it was designed for a HUX flow through, but I know those aren’t great for sound. Does that phased array give you lots of optionality, or should he be looking firmly one direction or another on the back pressure? I’ve watched like 20 hours of suppressor vids on YouTube but none tested on this system. Any help appreciated!

Here’s my new goofy hunting setup minus the can I’m picking up Friday. I really wish Rossi made a 1:5 twist so it would stabilize 220s better. Picked up some Barnes 205 grain and they work a lot better.

Last couple days have been pretty awesome! I have been giggling just thinking about this thing! For the low low price of 30$ I put this together.

This is currently legal for me to do where I live, and it really should be everywhere! But please make sure you check your state laws before you put together your own.

God bless America 🇺🇸 🤘🏽🦅 have fun boys!

I’ve been shooting for a few years now and want to step into the world of 300BLK.

I was looking online at different manufacturers and settled on the PSA 8.5” 1:7 twist nitride barrel for $219.99.

If I went shorter, I’d prefer a 1:5 twist. However, for an 8.5” barrel running supers most of the time, I think 1:7 is the better choice.

If you have any suggestions or advice since I’m new to the cartridge, I’d love to hear them.

Just showing off the progress on my Diamondback 300 Blackout SBR! Running it suppressed and loving the new Stark grip.

Finally got some needed accessories and new optic for this 8" 300BLK with a Quad Rail. I'm just waiting for my light and it'll be g2g.

I’m looking at buying this 7.62x39 AR pistol as my first firearm.
Is this brand reliable?
How does 7.62 compare to 5.56 and .300 Blackout for ammo cost and suppressor use?
Can I add a suppressor, optic, shell catcher, and light or laser?
Any issues with the 7” barrel?
Would you recommend this gun?

Lemme know your thoughts!

how can i get my 4inch 300blk run smooth ?

Just recently picked up a PSA Mixtape and am looking for suppressor recommendations.

I have been pretty sold on going ahead and getting the Mixtape suppressor, my only reservation is the lack of long term use and reviews that are out there on it. I know it’s specifically made for the mixtape which is what draws me to it, and haven’t necessarily seen anything negative about it.

I’m new to suppressors and have tried looking into a bunch of options, such as the Omega 300 or OCL Polonium 30. I know those are solid options, just not sure what direction I should go and am looking for any advice.

I have this old Aero Enhanced upper lying around with an 8” barrel. I recently disassembled a HB clone build I had and now have this 6” Q barrel that needs a home. Looks like none of my armorer’s wrench works for this enhanced barrel nut. Would it be worth it to buy a new wrench to swap these barrels?

It's a KRISS stock lmaooooooooo
