XCR in 300 blackout

The allure of of .330 AAC Blackout / .300 Whisper / .300-221 is that with this rifle, all you need to do is a barrel swap (from .223) and you're ready to go!

Same bolt and mags as the .223 model.

As a side note, I have learned that the Robarms .223 barrels are actually chambered in .223 Wylde making them suitable for both .223 Rem and 5.56 NATO ammo.

I have 1,000 300 BLK cases ready to load, now, all I need is the barrel !

PM me when you're ready for a barrel. I can point you to a guy who will make you a nice stainless match grade barrel to any length and contour you want.
 
You two should start a TV show. There's so much bs flying, we'll call it, "The News". (less a comment about content, more about delivery) If it takes off, you might afford some new elevator shoes.

Or you could go out and shoot. More round count, less post count.

Do you think anyone expects surplus ammo to deliver, as precision.

Keep empty posts like that flowing and soon you'll catch up in post count.
More round count, less post count? How do you know how much either of us shoot? I put thousands of rounds down range every year in everything from 17 Fireball to 338 Lapua and I'm pretty sure TDC shoots a lot more than I do.

No one expects surplus to deliver great accuracy but that's part of my point. There are so few choices in .311 projectiles that even if you reload for it the x39 could never compete with 300BLK when you want to try for smaller groups.
The 300BLK is a very easy cartridge to reload for and only uses about 20gr of powder for supersonic loads and around 12gr for subsonic loads so it's easy on the powder supplies in times like this where powder is not as easy to get. I load 110gr, 125gr, 155gr, 165gr, 168gr, 178gr, 180gr, and 208gr projectiles and all perform well.
 
It's very similar performance with 110gr loads in the velocity and trajectory departments but 300BLK can be loaded with quality projectiles any weight you want up to 220gr which in my opinion makes it outperform the x39 in all the areas that actually matter for field use.
I can reload 300blk for the same price as your crap corrosive surplus that ruins expensive rifles.
Not being able to use a suppressor isn't a problem, subsonic are still quieter than supersonic and the heavy rounds hit the gongs harder which is cool to watch and hear.
X39 is a round for cheap red rifles not black rifles. It also feeds like crap from AR mags (anything over 7-10 rounds), and you have no options other than FMJ, or soft point 124gr.
Brass for 300BLK is pretty much free since it is made from a 223 case so it's plentiful and easy to create.
300BLK also makes an excellent short range deer round with numerous bullet options.

No Fireball, it's not a fanboy cartridge, it is an excellent cartridge that does everything the x39 does and more and feeds properly from an AR magazine.

Interesting note....saved for reference sake

I don't dispute the 300 offers a much greater variety of projectiles for reloading and ultimately precision. What I question is why anyone would run a semi and/or an xcr in an attempt for precision? Reloading is time and cost prohibitive compared to surplus. In a semi auto surplus is king and if you're after accuracy there are more common and better performing calibres.

With 300BLK I run pretty much exclusively handloads since factory fodder is pricey, but for my 223's, my 9mm's, and my 45's I agree completely, surplus is the way to go. I do handload for all of those but don't shoot it that often. It's more for when I want to show what the rifle is capable of off the bench, for general blasting I shoot the cheap stuff. My 223's will never see Norinco ammo though, too many inconsistencies to risk my rifles. My pistols get fed anything I can get.
I don't mind the time it takes to handload, when the wife puts one of her stupid shows on the tv I go downstairs to the gun room and prep brass or play the slot machine till I have a pail of ammo.

Agree'd, XCR's aren't known for accuracy but that doesn't make them crap. They definitely have some issues with quality control due to the number of them that have problems before they even complete the break-in period but thankfully Wolverine has really stepped up and people can buy one knowing that if they do have issues that they will be taken care of.
Not all retailers are that good about standing behind their products, just ask mikethebike about his Christensen Arms AR.

If you're into hand loading and low round counts then the 300 works. As you say you have 223 brass to use for the 300 and its what you use for precision. For the majority who want a cheap to run volume shooter the 300 is a niche calibre that doesn't stand a chance against more commonly available calibres.

The issues with the XCR's isn't anything new, the RA M96 was a POS as well. For a pedigree of problems and an average shooting semi, its a poor choice for precision work with an expensive and rare calibre. As for Christiensen Arms they've been over priced since day one and have more than a few cases of lemons being sold. There isn't an AR on the planet worth $3500.

RA hasnt released the barrels for purchase yet as far as i know. Check out the xcr forums.
 
According to the XCR Forum, When Alex was asked about the 300 BLK, his replied was "it is very close" and based on all previous experiences that can mean any where between 6 months to 3 years.

As to the price of the conversion kit it will be $750, like all other conversion kits.
 
but we only need the barrel the bolt and firing pin are the same as .223 are they not? the barrel should only be $499
 
Seems pointless.

The only upside to the XCR is that you can get it in NR.

An 18.6" barrel completely misses the point of .300blk IMO.

A 8-10 inch gun in 3b is getting worthwhile because you can get a lot out of the cartridge even with a short barrel.

But then it's restricted anyway, so why screw around with an XCR? You could have an AR at that point, which is a better rifle.


I guess conceivably 110gr bullets could be used with a long barrel and you could hunt with it marginally better than with 5.56, or in provinces with a calibre restriction for hunting.

sure, chances are Wolverine will bring just the barrel for folks that own the .223/5.56 XCR and full kit for folks that owns the 7.62x39 XCR.

Your logic is falling on deaf ears...

I hadn't ordered one because I wanted to hear if anyone had issues with cycling. But because I couldn't get any feed back I held off. Didn't want to be the first test subject.

Appeal to the 300blk is that I reload.... Only need extra dies and keep all the same components for 223 and 308...

If the 300blk is a fail I'd consider the 6.8 or even 308.
