anyone heard much about this round?

Uh Oh. This is bad news. I have been thinking about getting a big bore AR. So many choices. Not enough money.

[bj139]

Here is a medium bore 358 ready to buy, load and fire. Much bigger selection of bullets.

the 358 uses a 6.8 bolt
the 400 uses a 7.62x39 or grendel bolt

[bj139]

Where would you buy barrels or dies?

[mdram]

no clue, maybe try the page linked in the article, and contact them

The update comments state it is not available commercially yet, still a wildcat, but of course you could have reamer made and chamber one yourself.

A 358 Gremlin (AKA 35 Gremlin) might be what you are looking for. I believe it was the FIRST wildcat based on the Grendel. Lots of bullets, and near identical to the 9mmx39 used a lot by the Russian army when it invaded Georgia. On the first forum before the crash some guy (from ?Indiana,?Michigan)had developed it and was marketing it along with barrels, brass and @ least two loaded bullets..

D tech in northern MN. can make any caliber upper, or just a bbl., if you have a reamer. I contacted him a few years back- he knows some of my relatives there.

He made the .358-6.5-243-- all on wssm cases. I asked what he had for a .40 cal. I was interested in the .440 corbon AR at the time. Only a few were made in the USA- then that round went away. He offered no options- but I can come up for lunch -anytime. And watch him make any bbl. I want !

So this new 400 AR wildcat is my close to- dream Heavy hitter for the AR . Plus off the shelf bolts, mags. I likey

I love that idea and was actually just thinking of a .40 to .44 caliber rifle this morning. I've mentioned in another place that my favorite short range round (100 yards or less) is a 200 grain .44 magnum fired out of a rifle. For whatever reason it just makes really large entry wounds, produces rapid blood loss, has low bloodshot, and enough energy/mass to break big bones and keep on going. Getting a bit more range out of it would be fun although I'm sure that it would come with a stiff recoil and more bloodshot at close range. Even the .44 mag pistol rounds make for a bruised shoulder without a recoil pad.

I currently have a .458 SOCOM and admittedly I haven't played with it much. It may already be what I was thinking of.

I have 2 458 Socom's. It's what you are looking for. Change the bolt, barrel and open the ejection port. Everything else is 5.56 based.

Almost any 45-70 bullet will work. Just make sure you get the original chamber by Teppo Jutsu, licensed out to Rock River Arms. Stay away from Wilson Combats 458 offering. Way too many problems there (repeat of the Grendel not being chambered to correct Alexander Arms dimensions).

Barnes 300 grain TTSX and H110 is a killer load!

In another thread someone mentioned the BCA side charging receiver has an ejection port big enough for 458 SOCOM.
I does look bigger on their website.

Ya, that was me. It works great with the .458. The BCA side charger is my go-to upper unless I specifically don't want a side charging upper.

Thanks for posting this info. I was thinking of of a big bore and I could make it work with only a barrel and bolt.

Sounds interesting, currently my short range thumper is a Ruger 44mag carbine. It shoots good and has killed somewhere around 20 deer and about that many hogs, for what ever reason it seems to really like 300gr Hornady XTPs which is ok with me. I have only recovered one bullet and ti weighed 278 grains and was .82 inches across and under the hide after going through both shoulders. Killed 2 deer one morning with one shot with it. Buck ran behind the doe I was shooting at about 70 yards that I didn't see coming through the scope and double lunged both.

I'm starting to grow an interest weed in the back of my not-so-smart brain for big bore AR/SR goodness. I currently have my long-drooled-over .357Mag Henry Hexagon to play with, but once I had it, shot it and put it away, I bought my first AR and have had nothing but Black Rifle Disease since. Grendel has much to do with that.

Seriously though, the 35 Gremlin sounds INTERESTING... the weed's sproutin' friends... ugh... time to get the empty wallet spray out again...

[bj139]

KSW,
These ARs are infectious. In the old days you would buy a rifle and it would be complete, nothing else to buy, and you shot it.
With the ARs there is always another inexpensive barrel to buy and excess parts that you must buy other parts for.
Many thousands of dollars later you think, "What did I need all these ARs for?"

I bought my first AR and have had nothing but Black Rifle Disease since. Grendel has much to do with that.

Yep, The ability to easily swap calibers has really brought new life into the AR, and the Grendel has really helped with that. The Grendel looks to be a really nice balance of energy, recoil, velocity and trajectory.

A .400 cal would be really cool to try though. I've used .357 magnum rifles and they just don't have the killing power that I'm comfortable with for big game, even under 100 yards. Maybe with some nice semi-wad cutter hard casts... The .44 Magnum rifles though can be WELL into the 30-30 energy levels, and with much bigger entry wounds. The .44 magnum is actually .429 or .430. I find the 10mm/.40cal diameter to be kind of "magical". It seams that when you get to that diameter, entry wound blood loss is significant and you don't have to use a bunch of velocity (blood shot) to get it.

My dad's (by extension, me...) has the .44Mag already. I wanted one of my own, but why have two of the same thing? I use the Henry to impress myself hitting cans on the fence at 70+ yards offhand, and loaded some XTPs for hexa-home defense rounds (lol), but never thought about using it for anything but against squirrels, bunnies, etc... It was mostly a target/cowboy gun, The 44 though, holy crap what a brush gun. Dad goes out with it and sits next to the roads on the public walk-in areas by his house (these are scrub patches the farmers can't come up with anything else to do to make them profitable, so they lease the small spaces to the state for WIHA...). Purpose driven use. Perfect.

Sorry to have hyjacked the thread. Back to the OP - I am surprised at the number of ways folks take a great thing and try to make it better... oh wait. Nope, this is just another example of freedom at work! Carry on...
