True, you can always have it throated longer if your not happy with the 115s.
.25 WSSM thread.. I'm starting over.
- Thread starter jeffreybehr
- Start date
That's the beauty of getting a zero freebore reamer and having a uni-throater. You can fine tune the throat to whatever bullet you prefer.
Have managed to find and buy about 700 Berger 115s, a combination of the current hunting bullet and the discontinued target bullet.. TYVM CKAB and jplahr!
Have more opened-box target bullets coming tomorrow..

And still I've been vacillating between the .25WSSM and the .25-284, and I continue to have trouble resolving my Savage-short-action bolthead for 0.532"-rim cartridge.. This is a confusing issue (for me, at least) created by Savage's refusal to sell complete bolts and also that the 0.532" bolthead is slightly longer than .473" bolthead..
Am investigating two solutions to this; more info later.
Also have sort of decided to concentrate on the Berger 115gn. bullets since I have over 700 of them, and I think I'll have the barrel throated for the 115 seated about halfway into the neck.. Also have 500-each of the Berger 135s and 133s ordered plus 250 of the Patriot Valley 120gn. Senecas and 500 Blackjack 131s.
Meanwhile, the shoulder-joint-REreplacement surgery is scheduled for June 08.

And here it is..
Of course, with its slightly longer snout, it wouldn't close on the 'old' barrel and chamber so I removed the barrel.. The black bolt is from my 110 Tactical Desert in 6Creed which is for sale.
The new bolt's cosmetics are identical to those of the original bolt, and most probably I'll switch bolt handles when the original returns from my friend in Tucson.

It might be the 25 SAUM...
It's the Remington 6.5 SAUM...
6.5 Remington Short Action Ultra Magnum – 6.5 SAUM
A little history Why is the 6.5 mm Remington Short Action Ultra Magnum becoming such popular cartridge in the world of long-range hunting and competitive shooting? I am hoping to help educate everyone and get some of these questions cleared up. Let’s start with how this cartridge came about,
bluemountainprecision.com
...necked down.. Loaddata.com's data on the 6.5 SAUM average almost 62 grains for all bullet weights (129 thru 147 grains).. Even if reduced to, say, 58 grains for the 25-cal. equivalents, that's still too much powder for me, as I'm building a long-range-target rifle and not a hunting rifle--and I'm WAY too old and chubby for the latter.
But thx for the pointer; I suppose it'd be next up if I want to go faster.

I've been interested in doing a 25 Dasher for a while, but can't convince myself that it's worth tooling up for since I jumped on 6.5 years back. I'm excited to see how the 25 WSSM does for you. Do you have a specific range or type of target shooting you want to pursue with it?
What I'm always concerned about is if the combination I'm looking at will reach a stable node before pressuring out or if I'll be stuck just below it and have to drop down to a "low" node to get the really sharp accuracy I'm after. On the flip side, the low node has always been better for me when it comes to pure BR accuracy.

I shot 1000yd. BR at Three Points west of Tuscon in 2007*, then quit for years, then restarted rifle shooting in 2017 when I bought the Savage 12BR in 6.5-284.. My current goal is to start load development with the Berger 115 and then go to the Berger 135 and/or the BlackJack 131 and/or the Patriot Arms Seneca120, all at 100 or 200 yards.. If succesful at 100-200 yards, I'll move to the longer ranges and, I hope, rejoin the Sahuaro club and shoot at 1000 yards again at Three Points.
My general problems are threefold--(1) I'm now 77 and a bit chubbier and shakier then I was; (2) I've lost most of whatever shooting skills I had years ago; and (3) I've definitely lost whatever load-development skills I had years ago.. And...oh ya...I've having my right-shoulder joint REreplaced in a couple weeks.. But there's some silver in that cloud--the shoulder ought to be well on its way to 'shootable' about when the barrel gets here.
* and one weekend won three of the four trophies awarded to LR and HR competitors.. That day I shot a 4-9/16" 5-shot group in LR and a 7-odd-inch 10-shot group (with my LR) in HR...BUT...it was all downhill from there.. Sold the expensive Shehane rifle and all shooting stuff in '08.. BTW I've owned THREE Farley front rests in 15 years, all from Bruno's.

WAHOO!
Haven't yet found the 133gn. hunting bullets.
Will be asking for throating advice soon.

I'm a big fan of the wssm. Just built a 243 wssm in a ar and love it. I can only load the 105 because of mag length. Have a model 70 in the 25 and it shoots lights out and been thinking about building a fast twist heavy barrel for 1k shoots good to know there is more folks like me out there that like the little guys!
There's a few of us out there.
Since i'm doing short range benchrest, (400.yards & under) i'm building a 250 Savage on a 1:10 twist.
The 100 & 200 yard matches will be with 75gr Sierra HP Varmint.
And since where i shoot has some switchy winds i'll go 110-115gr bullets for the 300-400 yard.
Still following the 25WSSM build with interest!
I love this thread. I can't wait to see how Jeffrey's new rifle shoots. I've owned two rifles chambered in 25 wssm since 2006. A Browning A-bolt composite stalker and a Winchester model 70 coyote. They aren't barrel burners. Simply because they can be loaded to 65,000 psi does not make them barrel burners. Best group I've shot with my Browning was a 3/4" 3 shot group @ 200 yards. This load was 115 grain Barnes tsx bullets loaded under H4350. The model 70 likes 115 grain Nosler BTs. It shoots them inside an inch consistently at 100 yards. I'm not a bench rest guy. I do hunt at longer ranges, and my model 70 is topped with a vxii 6-18×40 with a laser etched turret from Kenton industries matched to the 115 grain Nosler BTs. I usually load those bullets under Superformance to achieve 3000 FPS that is necessary for my turret. It offers the highest velocities for the 25 wssm with 100-120 grain pills. I now have 15 years experience reloading the 25 wssm. I was making 25 wssm brass from 243 wssm brass when all I could find was 243 brass. Super easy one step process, and I think it makes for better brass then 25 winchester brass. It seems to soften the necks up a bit. Winchester brass isn't the best, but the necks can be cleaned up nicely if you have the time. I've probably put 1600 rounds down both barrels. I shoot prairie dogs with the 75 Vmax's. Great bullet for varmint shooting, especially at almost 3800 FPS. Those barrels get hot when you're having fun. My barrels are still in excellent shape and both rifles shoot as good as new. I can consisting hit prairie dogs to beyond 400 yards, so I'll call that good enough. I've shot 2 bull elk, 5 pronghorns, 5 muley's, and lots of coyotes and bobcats with my 25 wssm. It is an excellent all around cartridge. My favorite load is the 100 grain scirocco ii loaded under Superformance. It can achieve 3380 FPS which shoots very flat. Sighted 2 inches high at 100 yards it'll zero itself at 340 yards at 8500 feet above sea level. I find no advantage to shooting the 115-120 grain bullets out of mine, unless your wanting a little better performance in wind drift beyond 700 yards. The 100 grain scirocco performs slightly better to 700 yards than the 115 Bergers do in drop and wind drift. The biggest reason for this is the difference in muzzle velocities between these bullet weights. 3380 FPS vs 3100 FPS. The Bergers don't shoot well out of either of my rifles. I don't think they are a good bullet for hunting either. I shot a black bear with the 115 grain Bergers at 50 yards through both shoulders. I never could find that bear, and that made me sick. They're just too soft especially at close range at a high muzzle velocity. The shooting I've done at 750 yards leads me to believe that the 115 Nosler BTs are nearly as good at bucking the wind as the Berger Vlds. You'd be splitting hairs between the two, and the Nosler's are much easier to get to shoot. They also have a thicker jacket for hunting purposes. If I had a 1:8 twist, I might try the 130-140 grain bullets, but I personally think that these long heavy bullets are only good for extreme distances beyond 800 yards where it counts. And I own a 30-378 for that.
I believe that. The 115 Berger Vlds don't group well at 100-200 yards. 2 inches at best. But they do hold good accuracy beyond 500 yards. If I were building a gun I would try throating the barrel to shoot the longer heavier bullets. By tuning it. But that gets to be time consuming and expensive. But again I'm not a bench rest competition shooter. If I can hit a 15-18 inch plate past 700 yards I'm good. Since that's about the size of a deer sized animal's vitals at center mass. An elk's vitals are even larger. These match bullets are only good at lower velocities when hunting. They explode on high velocity impacts. I think the sciroccos and accubonds are much better all around bullets and they have pretty high B.C.s. Especially when you adjust the B.C.s for atmospheric conditions at high altitude. I think the 100 grain sciroccos have a .8 B.C. when pushed to above 3300 FPS at 11,000 feet above sea level where I hunt elk. Why even shoot the 130-140 grain bullets when the lighter bullets shoot better from a standard 1:10 twist and have a nice high B.C. when you correct for atmosphere?
They don't "explode", but they do come apart.
I've found that the Berger VLD performs exactly as advertized. Goes in 1-3 inches, then rapidly expands.
With the deer i've shot (and my daughter) we haven't had an exit yet.
As for the Accubond, seems either your rifle likes them, or it doesn't.
I just can't get them to shoot from my rifles.
I wish Nosler would make an ABLR for the 25 caliber!

No 100 grain bullet carries a .8 BC. I'd give it maybe a .5 max but believe a .4 is more In line with a 100 grain BC of a .257 bullet. Hell, I haven't found a .7 in the heaviest .257 bullet. The .6+ BC .257s in the 130-135 weights is very impressive IMO. To get into the .8, you'll be getting up into the .284 heavy's.

I will just put this out there for info purposes, as I no longer try to convince shooters of anything. I started BR with a 700 brx brcame a 6SUPER LR, BARREL WAS CHANGED TO A schneiderP5 7.5twist.treatedpowder,barrel and bullets. i expect it to last forever
