Best 7mm cartridge?

[john338]

280 ai. Almost the 7mm mag velocity with manageable recoil and good barrel life.

I like my 7mm rum.
Curious to know what it is about the 6.5 PRC that makes you unhappy?
I've been contemplating one.

Look at the new 277 Fury.
140 Grains, 3,000 FPS, 16″ Barrel
There have been all kinds of numbers circulating, but the facts are that a 140-grain bullet will attain a velocity of more than 3,000 FPS from a 16″ barrel. Exact chronographed velocity won't be finalized until it's checked in SIG Cross production rifles but at least 3,000 FPS is certain. Obviously, longer barrels are going to mean even faster speeds.

I like the design of the Sig Cross...light weight, short barrel, folding stock, one piece receiver. Waiting to see what accuracy looks like, and the uptake on 277 Fury vs 308 and 6.5CM. The latter two rounds will be good enough, so the 277 Fury will have to knock my socks off AND emerge from proprietary status before I'd go that route, personally.

Hey y'all I'm kinda new to shooting really far. I got a 6.5 PRC right now but I'm not really happy with the rifle and I was looking at getting a new one. I really like 7mm (Especially the 195gr EOL) I'm just curious what cartridge I should shoot. It's going to be a long range target gun (around a 1000) and my elk rifle. Any recommendations for cartridges or rifles? I was considering building one but I'm hesitant because I don't really know what I'm doing. (I was looking at 28 Nosler but the brass is expensive and I'm not quite sure if I need that much rifle)

Creedmoorshooter & myself have had good results from 180 elds in factory twisted 7mm rm heavy barreled 700s. Mine is a sendero & his is a 700 long range. It's mixed bag results with 180s in factory 700 7mm rem mags so it may not be a gamble you want to take. Years ago there were a few folks winning matches with 280ai and straight up 280 rem pushing 180s but those were custom rifles.

I'm shooting a 284 Shehane (improved 284 Winchester) with 180 vld's at 2790, could go higher but this node is very broad and stable at various elevations (500 ft to 6800 ft)

I have 2-7mm rifles. One custom 7SAUM and a Legendary Arms 280AI either works out to 1,000-1200yds and will get done what you want it to. See other posts about the 28 Nosler is great long range but they are in fact hard on barrels and shoulders.

Anyone else a fan of the 7SAUM? Really like mine.

Big fan been shooting mine for years for hogs in California and mule deer in Oregon and elk great accuracy and works great

OP said 7mm, elk, 195's, 1000y. Best recipe for that is 28N with a brake.

 

[Ace Quackhunter]

I think the 284 Winchester is hard to beat for knocking down elk.

 

[DJ Fergus]

Funny you say that, my mentor/friend that retired from gunsmithing said he hated the 7rm and could never build one that performed. I've only owned two and sold them both

He's taking about the 7mm LRM not the 7mm Remington magnum

Im running 195's in my 7 SAUM at 2900 fps. Super polite to shoot and great ballistic performance. My SAUM is set up on a long action.

 

[WahooYahoo]

So the rifle specs for both rifles were exactly the same, yet 14 grains of powder only added 50fps? Was the Nosler reamer a saami spec with the 195s?

The Nosler chamber was throated for the 195 to sit at the neck shoulder junction, so it has a long throat. I'm not saying that the Nosler load can't be hotter. if pushed a bit, it might be 100 fps different. But that would be an even greater powders wt disparity. My point is The Nosler was designed to turn a lighter bullet into a bolt of lightning. Its horribly inefficient and far from a sweet spot of "costs".
The Max has improved all that was wrong with the SAUM. Better brass aside, the bullet is where it belongs in the neck, the few extra grains of powder get it to 3k fps in the big pill, 31xx in the 180's, 40 degree shoulder reduces case stretch, an so on. The one concern I had regarding feeding a short fatty is reportedly disarmed with the "Kwik Klip" magazine.
BTW, in the example I gave, both are loaded with N570
