Winchester's new 350 Legend cartridge 35-223 AR compatible

[ARCHIVED THREAD] - Winchester's new 350 Legend cartridge 35-223 AR compatible (Page 1 of 11)

Posted: 1/19/2019 10:44:24 PM EDT

This should be an interesting new cartridge. .35 cal on a blown out .223 case. 2000 fps with a 200 gr is pushing 35 remington ballsitics. They are rolling this out at SHOT.

So.......a 350 blackout? ;)

But muh .30-30.

Oh hell yes, I want one right now.

I’m intrigued.

If this out Blackouts the Blackout, it could be pretty cool.

Interesting...would definitely be popular in areas that only allow straight wall rifle cases for hunting.

Sort of want because reasons...

I approve.

Interested to see what comes of that and who makes parts for it. I might "need" one of these.

I see a new upper build in my future.

I love 35 cals. There's a huge variety of bullets from 110gr pistol bullets to .250 gr heavies. I expect 200gr would be about the limit with this new cartridge without taking up too much powder space. Although really heavy subsonics might work.

What are the chances that the only thing a standard AR needs to function with this cartridge is a barrel?

I would imagine the standard BCG will work since .223 is the parent case, but what about mags and buffers?

So it's a 38-55?

I've got a feeling that standard .223 mags are not going to feed right.

The old 38-55 is .375 cal.

Hmmm, interested in seeing what velocity you can get out of a 16" barrel with 200gr bullets.

I am throwing out my Blackout and Creedmoore......

Posted: 1/20/2019 12:16:39 AM EDT

[#18]

That actually is pretty cool.

I want a contender barrel for it. Although I guess 357 max would make more sense for that.

On any decently long barrel I would think most 9mm cans would handle subs just fine, too.

A straight 20-rounder might.

Hrmmmm. I just got into .357 max this past year. I'm not sure my 16" barrel could get a 200gr bullet to 2000. If nothing else I hope .35s get popular and we get more velocity appropriate bullet options. I'm kind of in no mans land with 180s.

Derp. My bad. Still, not that far off 38-55 & 375

Straight wall case... so no trimming? If so I might be in.

Absolutely hate case trimming.

Posted: 1/20/2019 12:32:12 AM EDT

[#25]

2000FPS at 200 grains, is pretty good.

It looks like this new round will be longer than the .357 Max, so more case capacity.

Enough to get a 200 grain bullet to 2000 fps...well, that remains to be seen.

[#29]

Meh, I'm not understanding the point of this?

Why are y'all interested in it? I'm more utilitarian though, and it seems other cartridges would do a better job at killing, so?

Hmmm.... I may need one of these.

Posted: 1/20/2019 12:39:47 AM EDT

[#31]

That’s cool.

If you want a different option than 300 blkout, it works.

I think I’d just take a 30/30 for that kind of thing though.

If they did it right, this fits the world of standard AR parts.

In that context, a straight wall .223 case is basically the biggest cartridge you're going to fit without sacrificing capacity or common parts.

Hopefully, we're looking at something that has much better subsonic terminal ballistics than .300blk. This could be America's 9x39mm.

My main interest is in a small bolt gun in this chambering. Zastava Mini Mauser, CZ 527 or Howa mini action.

Sounds interesting, however, the appeal with 300 BLK is using suppressors. Not a lot of suppressors for handling .35 Cal. Hybrid or whatever it is from Griffin...

Posted: 1/20/2019 12:55:48 AM EDT

Very exciting cartridge. Similar performance to a .357 magnum carbine, with 25% more weight.

This is a 9mm bore diameter.

If the pressure of the cartridge isn't an issue, most 9mm or .45 cans will work.

Interdasting.

I will keep an eye on this.

Factory .35 Remington ammunition won't make 2,000 FPS out of a lever action barrel.

Interesting cartridge indeed. Maybe the most useful deer hunting cartridge yet for the AR.

ETA: their math is wrong on the magazine cover. That or the writer is just lying because they've been paid off to promote a new cartridge. 1,776 ft lbs doesn't equal 2,046 ft lbs available from a .30-30 Winchester.

Posted: 1/20/2019 1:08:44 AM EDT

I have one right now. Go over to variants and look at 357 AR max.

Posted: 1/20/2019 1:12:12 AM EDT

They need to do the same thing for big frame guns in .45.

I wonder if Winchester is actually not the big player behind this round, because this has AR15 written all over it.

Pretty much as subs only though, not supers. Will have to see what the Silencer manufacturers say.

I would be interested to see what MDWS could do with a 35 caliber bullet in their new line of 6.8 case-based wildcats..

@MDWS.

Oh and please hurry up with the 30 cal variant

I'd bet subsonic loads are going to be announced real soon after the release. This would offer a nice alternative to the 300 blackout.

The more things change the more they stay the same

- Looks similar tothe 351 Winchester Self Loader (Circa 1907) that was semi-popular for law enforcement through the 1950s when othre post-WWII semis like the M1 carbine became wider available.

351 WSL on left side of this picture below - 5.56 on extreme right.
