Great article, although I would compare them to gasoline and diesel. One has a little more torque and power while the other is a little faster. Both are great at what they are designed for.

Thanks Mike for the article! Next we need too see wind hold for the 4 different grains. The 300bo would be interesting! As an sbr/pistol the bo isn't too bad 200-300 yards. TSiWRX posted in a 300bo thread about a 1k yard shots with this cartridge. What was funny about it is one said it has an effective range of 1k yards. Just so you can shoot it that far doesn't make it effective! I think it's just blind luck!!! Every cartridge has a purpose for its range. I still haven't been able too get better clarification what is classified as effective. When I see the difference between a 300wm and a 338lm, there isn't much change. 200-300 yards at most. If you have any information about "Effective Range " terminology, please let me know! I have 2 8 1/2" and 1 16" barrels in the 300bo. The 16" is more for testing against published load data. It is a good caliber for what it's intended for! So many people scoff at this cartridge! Thanks again! Mike at Armory Life!

I always say effective range is what one has trained for and can perform at reliably. It may be different for everyone.

Between the 300wm and the 338lm when it comes too effective range I have seen the 300 listed as 1,200 meters and the 338 at 1,400 meters. I think there should be more spread between the two!

I dont know, but I would be more than willing to find out had I the time and resources.

I have both 300wm and 338lm in Savage 110 Stealth, so I would have good comparison for 24" barrels. The scopes would be the only difference besides the cartridges.
Question is would you have the range to accurately test those?

About 3,000 yards should be enough!

To be honest here, I have never shot the 300BLK, so really I couldn’t say either way.

It's a good cq gun, unless you live in 1 of those states where it is 10 rounds or less mag cap. Home defense cut the muzzle energy down to 500-700fpe. Then you have a high powered high capacity pistol with great control!

Ohio here, no magazine restrictions, I may have to try one out, seems like a lot here shoot that, looks and sound interesting.

What kind of bullet weight would you look for?

I'm coming at this completely subjectively... I've shot sub-sonic .300 BLK supressed and it was very cool, quiet, with minimum recoil. My AR556 is a growly cat and (so I've heard) a suppressor will only have so much net effect. Point is, for more enjoyable supressed shooting, I've heard (and experienced) that the .300 BLK is the way to go.
Again, a completely amateur opinion. Your mileage is sure to vary

For factory sub ammo your options are limited, but hand loads will give you more flexibility. 50 yards or less maybe 100 yards possible!
Heck I need to come to that range lol. The biggest I have here is 500 yard.

For me it’s Not so much a need but an enjoyment in shooting all 4 of my AR platforms. I’ve yet to get my mind wrapped around all the specs of each round and what they can and cannot do I just enjoy kicking back on any given day and putting rounds down range and holes in paper. My satisfaction comes from getting better every time I shoot.
