NEW 338ARC, what say ye?

[Formidilosus]

What’s the case fill on that load?

Not much. Trailboss is the way, but hasn’t been available in years.

I have half a pound of Trailboss that I should use. Fudds and their cowboy loads hoarding it and not using it.

Ahh. Trailboss and subs are a great combo.

I’d bet decent money if they did a gel test of both sub-x offerings you couldn’t tell the difference.

I know you're probably right, but in the video it seemed to tumble and they claimed its an improved sub-x bullet. They both suck in the grand scheme of things

 

[RockAndSage]

There might be something to be said about it filling out the ARC "ecosystem", in that it might make sense for bolt and magazine commonality if you're running a different ARC or a grendel and want to keep things a little uniform, while also getting into something specialized for subs. It's an option, but not any kind of game-changer.

I celebrate the arrival of every new AR15-length cartridge for two reasons:

- It helps normalize and sell more ARs
- It keeps my hopes alive that a manufacturer will bring a truly excellent micro bolt action to market

 

[ShadowAviator]

It seems to fit into their ARC line pretty well. The 358 Gremlin is a similar idea. Grendel case, 358 bullet.

If you are going "AR10" size, the 375 Raptor made more sense to me. Good subsonic performance, and beats the 8.6BLK supersonic.

I’m all for these new tiny little cartridges and sure am hoping it pushes someone to start offering an appropriate tiny left hand action!

 

[rharbaugh]

if I want to shoot subs, it’s a 308 so I at least have a real cartridge when I want.

Form are you shooting subs for fun or purpose? What bullet do you use?

 

[Ozarkansas]

There are specific powders and loads that work, but not too bad.

100 yards, 1.5” dots.

I’ve had good luck using similarly tiny amounts of Unique and cast bullets- I guess it never occurred to me that I could use jacketed bullets too (since I learned about it from guys who only shoot cast bullets).

To those of you who haven’t tried it, some of these super fast burning flake powders ignite so easily that “case fill” really isn’t a concern

Cheers to a truly excellent micro bolt. If I were hornady I’d be teaming up with TC to build a micro series of Icon rifles. I’d also get Ruger on board to make marlin 336’s that shoot the ARC. Gummy tipped 22 and 6mm bullets

When was the last time a cartridge over 30 really took off?

350 legend?

350 legend?

Yea probably, although that one is popular not really on its own merits, but because of state hunting regs.
