7mmSTW or 7mm Ultra

7mm Ultra does not appear to have much over the 7mmSTW, especially considering the increased powder used in the ultra, costs etc. Of the two cartridges, which one will still be around and available in 5 to 10 years?

I just dont understand all I know about this 7 mag. thing.....The long action and STW will both be replaced, by the short 7 mag. and the truly great Rem. 7 mag....Thats what I think in 5 years or so, and i would purchase my 7 mag. rifles accordingly...why all the options????..the Rem 7mag. was all we needed, but the short action has its benifits...I guess....sakofan...but what do I know, I said Def Lepperd would be the next Led Zepplin after I saw them in concert in '82...what was in those brownies???

I own both the 7mmstw ans the 7mm ultra and find only about 50 to 75fps difference with handloads.I personally prefer the stw because they will work in the remington detatchable magazine which I prefer over a floorplate.The 7mm bore does not appear to be large enough to offer much advantage with the ultramag case.I do however much prefer the 300 ultramag over the 300 weatherby mag.

The velocity difference in the STW and the 7mm Ultra is within the variation of two different barrels shooting the same cartridge. In other words, a "fast" STW barrel might give you as much or more velocity than a "slow" Ultra barrel.

Given that their practical velocities are so similar, I see no advantage to the Ultra over the STW. With the STW (1) your brass will be less expensive, (2) your magazine will hold at least one more round (and you'll avoid the feeding difficulties that have been exhibited by some guns chambered for the "fat" rounds), (3) you will need a bit less powder for the same velocities. Less powder means a little longer barrel life, but either cartridge will have a relatively short barrel life (meaning that if used only for serious hunting, your great-grandchildren may be faced with rebarreling the rifle).

I suspect that they will both still be "around and available in 5 to 10 years". Should either or both be dropped in factory chamberings, it will just make a gun so chambered more valuable.

Gentlemen,

I'll keep my 7mm Rem Mag. It works every time, and I suspect it will keep doing everything I need a 7mm rifle to do for quite some time to come.

I think the Ultra is overbore & will drop from favor before the 7STW. The STW is @ the limit of overbore as you can see by reports from the other guys, too much powder for too little vel. gain. Just buy 300rds of brass & don't worry what happens in 10 years.

My buddy shoots the STW and I shoot the Ultra. We can see no practical difference between them. I believe both to be "specialty" calibers. My Ultra is a Sendero that functions and shoots perfectly. I am getting 3400fps with 150 Sciroccos. I use a 6.5x20x40 Leupold with a custom reticle in Talley mounts. The rifle is used to shoot targets at very long ranges. I will also use it this fall to pot Mule Deer across canyons, again at very long ranges. I think the big sevens are maybe the best long range deer killers I have seen, but don't plan on using my own for any other game. Both catridges are loud, and gulp huge quantities of powder but don't let anyone tell you they aren't accurate. The short and fats can't run with either of them but almost certainly will get better barrel life if that matters. Pay your money and take your choice but if you are looking for a good general purpose hunting catridge I believe there are better choices.

Steven-

Back to your original question, what cartridge is going to be around 5 -10 years from now; the answer is the 7 mm Ultra. The 7 STW is already going the way of the 6.5 Rem. Mag. I could be wrong but I don't think there are any current manufacturers chambering for the 7 STW. Thus, brass and ammo is going to become increasingly scarce.

Good luck!

Yes, you could be. There are currently more manufacturers chambering the STW than the Ultra. Added to that thousands of STW's produced both as wildcats and as factory chamberings in the many years prior to the advent of the Ultra, it is highly doubtful that there will ever be as many Ultras in circulation as STW's.

However, I doubt that the owner of either will have any real difficulty finding ammunition in the foreseeable future. In the unlikely case of an ammunition scarcity, advantageous to the STW is the fact that a number of different cases produced by a number of different manufacturers can be used as the parent: 375 H & H, .300 H & H, 375 Wby, .340 Wby, 300 Wby, 8mm Rem Mag. The only other case that the Ultra can be formed from is the .300 or .375 Ultra, although arguably, the shorter .338 Ultra might work in a pinch if you don't mind an abbreviated neck. Currently, only Remington is producing this line of cases, and I suspect that the Ultras will remain proprietary with Remington. On the other hand, Remington, Winchester, Federal, Hornady, and maybe some others are producing STW ammo and cases.

Given these circumstances, it would seem difficult to defend your presumption that the STW will become obsolete and the Ultra predominant.

Agreeing with Stonecreek, the brass would be the deciding factor, I handload for a couple buddies with the STW`s and Winchester has all the new brass you want for the STW. If you go with the RUM line then Remington will be the only choice. I wish Lapua made brass for everything. [Mad]

The line of full-lenght lazzeronis ; 7.21 Firebird,7.82 Warbird and 8.59 Titan,,equates to SHARP RECOIL !! [Eek!]
I think laying on the ground with the 7.21 Firebird with a scope and full tilt loads ( 3600 fps with 150 gr.)is going to make a nasty cut !!....(not at least 8.59 titan, 3150 fps@250 gr.!!!)
