25 X 47 Lapua

[p-man]

Just curious if anyone on here has any performance results with 100-110 grain bullets in this chambering.

I have never chronographed my 25x47 loads. That said, using 110 Gr. BT, a Bartlein 1:9" twist barrel, CCI-BR4 primers, and a healthy, but not excessive charge weight of [now, discontinued] IMR 4007, I collected some NBRSA HUNTER CLASS NATIONAL CHAMPIONSHIPS: a pair of 200 yard and one Grand Agg win. So, the cartridge, teamed with good bullets and barrel, is quite capable of excellent (BR quality) precision. Since the case-capacities are nearly equal, I'd expect velocity the same as via 250/3000 Ackley Improved - about 3100 FPS +/-. RG

I do not own one but I researched them quite a bit before going 6.5x47. I think the case capacity, good brass with the small rifle primers would yeild over 3000 with most powders in a 24". Depending on if you are after accuracy or speed there are probably powders that would push into the 3100 range at 60kpsi if throated properly. You can seat these out a long way and make full use of case capacity. I did this in my 6.5x47.
Had there been a better variety of heavies in this caliber I would have went this route when I built.
I will be following this as I still find this cartridge intriguing. I also find your bullet weight. choice to be interesting. You would have a rifle capable of a lot of variety. varmints, predator, deer, target, prs...

RGR, I did have a 6.5x47 ten years ago and let someone talk me out of it. I've always had at least (2) 250 Savages for kids or the SA, plus an Ackley for myself to play with. My latest future project list includes two 'quarterbores':

#1 is to build a version of the original Howa Alpine; I have the lightweight action, the Alpine stock, and a .257 barrel that fairly duplicates the contour. My original intention was to do another 250 Sav, but now I'm thinking that maybe the 25x47 would be a fun match for that setup - the only change would necessitate getting a new bolt but that's not a gamechanger. My barrel is a 10-twist and the little gun would probably never shoot anything but southeastern whitetails, so I think 100-110 grain bullets would be the ticket. I know the original 6.5x47 was developed for loads up to 66,000 by Lapua, taking advantage of the stronger case available with the small rifle primer - and that was the premise for the effeciency of the velocities obtained. I've always wondered why the cartridge was not pushed or marketed for hunting AND target like Hornady did with the CM. Still I'm sure I'll never really push the boundaries in this rifle - velocities in the 2800s with this little case would suit me just fine and still be a great kids rifle.

#2 will be a 25CM on a Sendero-type rifle/stock combo that will be mostly for punching paper and steel. As I do composite stocks, I've already started on my stock and have an action but still holding out on the barrel. I would still like to see Hornady or anyone for that matter, formalize the 25CM with SAAMI. I'm still gunshy after what Nosler did with the 280AI, so I'm not going to complete a build assuming that what ends up with the SAAMI stamp on it, is going to be what we all know as the 25CM today.

Anyway as Linebaugh says, I too would like to follow your continuing results/development if you don't mind sharing updates every now and then. My current 250AI is throughj 9-twist Rock Creek and pretty much those loads can be stepped down as starters when I do get going with a 25CM, but you're the only one that I'm aware has anything current with the Lapua.

Thanks much,
Py

I have one that was built by Alex Wheeler. I use BIB 110 grainers. It was stupid easy to tune, shoots itty bitty groups, recoil is a non issue. I don’t remember the details but I’ll check it out when I get home.

Based upon history, I wouldn't wait on a SAAMI spec'd 25Creedmor - or, any other .25 caliber . . .
Why would you need a new bolt - the [parent] 6.5x47 LAPUA shares the same case-head diameter as the 250 Savage (250/3000).

I also have a 6.5x47 Bartlein 1:9" twist barrel which fits the same BAT actioned Hunter rifle. When LAPUA SAAMI spec'd the 6.5x47, I acquired brass and had Hugh Henriksen make chamber reamers for 6mm; .257; 6.5mm; and .308 - as expected all GREAT reamers.

Following an appropriate wait, a few days before a tournament, a set of Ulrich 6.5 dies arrived, so, some bullets were made! Having never fired a shot through it, prior to the opening "commence fire" command, at a NBRSA registered tournament, the the 6.5 barrel (H-4350) was "tuned" during the 100 Yd. stage - the last two targets were "cleaned" - 100 & some Xes - I was 7-8 points "down" close to last place . . . but, it was exceptionally tough conditions that weekend -so, there remained some hope.

That barrel/bullet combination proceeded to nab the "fake wood" @ 200 Yd, 300 Yd, & the 200/300 Yd Agg. and was still good for 2nd in the 100/200/300 GRAND AGG . . . while beginning a tournament using a never fired barrel is not recommended procedure, I wanted to test the bullets produced by the then NEW George Ulrich 6.5 dies. Another GREAT Bartlein barrel and Ulrich die set were proven. There is no better proving ground than point-blank BR - either group, or, score.

There is a LOT of unproven "stuff" which will "work", but few willing to test/risk, "looking like a fool". Sometimes the uncommon disappoints . . . sometimes, as was the .25x47 LAPUA project, it's a rousing success - that initial Bartlein barrel never finished lower that 5th place in a NBRSA registered Hunter tournament. AND, still, to my knowledge, nobody else had one made and campaigned it on the circuit ! RG

 

[p-man]

you are absolutely correct, my brain was in the wrong gear

 

[TZaun]

I shot a 25x47 for mid-range F-Class a couple of years. I too shot RG’s 110 BIB bullets out of a 9-twist 30” barrel. I tried Varget and H4350 and Varget shot considerably better and could push them much faster. I found 2 nodes with Varget around 36.6 (3020 fps) and 38.0 (3110 fps). Very good accuracy.

 

[Preacher]

Double lunged a slow moving doe at 200 yards with Randy's 110's, she went about 30 yards..
Shot was centered between 2 ribs on the way in, and broke a rib on the way out..
Made a pretty good mess of her lungs..

Hopefully that bullet becomes available again in the future. Great bullet! Congrats on the deer!

RGR, what really convinced me before I did my 6.5x47 was the article on some dude who had already done a 7x47 with surprising results coming out of such a small case. No matter what anyone building off a 47mm Lapua, can always easily rechamber to a larger, short-action case; in this case from the 25x47 to 250 Sav AI or 25CM. My enthusiasm is beginning to spool up

 

[Preacher]

I hope so too, I'm down to 70 of them, but thats 70 more deer...
Shoot them out of my 25-6.5 x 55 SM also....

 

[JPB3]

Don't know about the .25x47 but I've done several .25 Creed's.. In my mind it was and is a great success.
Only used it to hunt but they, several of them, shoot very well with 100 Nosler BT's and or the 115 Bergers.
For my use the 100NBT steals the show.. Using 6.5 Lapua sp pocket brass necked down was able to get amazing velocity with great accuracy.. Think near .25-06 performance. Deer and coyote killer

Preacher, somewhat rare to take the 6.5Swede to 25 cal. I think it is great idea.

 

[Bodhisafa]

Is the x 47 case big enough to push the heavy 25 cal bullets fast enough to take advantage of their high BC?

I'm using a 28" Bartlein running 135 Bergers at 2880 and 134 ELDM at 2820. I've run both up into the low 2900's but they shoot well going slower. I will say it was the hardest cartridge to get into a good tune I've ever shot but has been pretty stable once I got there. Maybe just the very long bullets and fast twist needed?

Maybe try some RL15 if you can get your hands on some... Should be close in burn rates and I have had some very good results in a 6BR. H4350 is just slightly slower but also should perform.
