Debating on acquiring one - partly for a HD weapon, partly as a truck gun, partly to annoy liberals, partly for the hell of it smile The house gun is a 16" .300BO, loaded with supersonic ammo.

Can't quite decide on whether I'd want a pistol caliber, a .300 BO, or a 5.56. Shot next to one guy at the indoor range, who had a 5.56 pistol, roughly a 10" barrel, and it was utterly obnoxious as far as muzzle blast. Think he had a standard flash hider on it, and I know some of the devices like the KAK cans help direct blast forward.

I've seen a PSA 9mm pistols recently that were reasonable priced and seemed decently made. The last I read, people who had intensively studied PCC's were not impressed with them for defensive use.

Thoughts?

Been involved with a few short barrelled AR's - 556 exclusively, Velocity loss is incredible - no, I did not chrono the loads, dead on at 25, 12 inches low at 100, 6 inches low at 50.
Not something I was interested in, personally.

Looking at a 9mm AR to complement handguns (less variety of ammo)

Also, REALLY looking at 350 Legend.

Worked a lot putting together PSA, nothing wrong with those weapons or the company. MILSPEC is MILSPEC, period.
I did put together a couple of PSA 308s and there is no MILSPEC on AR-10, thus I've been told uppers and lowers between companies are not compatible - but I really can't verify that.

Curious what kind of load you were using to get that kind of a rainbow trajectory? A standard velocity 22 lr shoots flatter than what you’re describing from a 5.56mm

I do have a BCA .350 Legend upper, and it shoots well, and kills critters well. In a pistol? Hmmm...

One of my gripes about the .350 is it needs special magazines, which defeats the purpose of commonality with the numerous 5.56 mags. The .300 BO works well with 5.56 mags, although I know some do make special mags for it, too.

mine in 300bo 8.5 inch barrel hangs next to the door on a hook. dog wants to go for a walk every time i touch it.
we have a wolf problem here so it goes on every walk with me. i seldom grab my 9mm S&W anymore.
also have a 10.5 inch 7.62x39, and a 10.5 .556. don't shoot them as much what with the component shortage right now, but the 7.62 sits next to my nightstand. it is fitted out with light and laser etc.
i should thin the herd but..........

i like the 300bo for the weight range of bullets it will handle.
ymmv

Yep,
Total bullshit.

With a 10.5" barrel you can get 2800 out of a 52gr NCC.

Here's what a 250 yard zero looks like:

Typical 55gr ammo will get you 2700-2800 fps from a 10.5".

With a 25 yard zero, you should be hitting 5-6" high at 100.

I zero my 10.5" 5.56 at 40 yards.

It hits 2" high at 100, and is back on zero at 200.

If true, you had other undiagnosed issues.

You claim that the bullet dropped 6” in 25 yards (between the 25 yard zero mark and 50 yard target). Never mind that a person could literally throw a baseball that distance with a flatter trajectory. You then claim that the bullet dropped another 6” while traveling twice as far (50 yards) even though the bullet is continuing to slow down and should be dropping at a faster rate.

Not saying that you’re lying at all but it defies any experience that I’ve had and defies physics. I think something was wrong with your setup.

He wasn’t actually zeroed at 25.

For lost people the group dispersion at 25 is large enough to be incapable of verifying that the group is actually zeroed at 25 or if it’s a bit high or low. And a bit high or low at 25 can be a big deal.

This is why we get on paper up close and zero at long range.

Those that zero at 25 or even 50 yards will never know where they are sighted at 200 yards until they shoot it.

3” difference in drop at 100 with .8” difference at 25.

My 11.5” with a 25 yard zero.

Same load with a zero that’s .8” high at 25 (which is very likely with most people’s 3 shot zero process)

I ran the numbers in Strelok.

12” low at 100 is 6” low at 50, and 4” low at 25.

I’ve been using an sbr at work for many years. Yes they are loud as hell but handy in confined spaces. I wouldn’t go less than 10.5 if i were to build or buy one. Just my personal preference and I’d stick with 5.56.

PCCs are a hoot. I've had a couple and shot quite a few more. They're notoriously unreliable. The only model that has an across-the-board reputation for reliability is the JP, which I have now and should have just paid the money for to begin with. A few friends have MPXs that they trust, now that they've worked out the kinks and proved them reliable.
