25x47 Lapua load data

[Birch7]

I should have my new 25x47 soon. Anyone have starting load with Varget and a 134eldm? Thanks

Start at 35. 37 grains put me at 2870 at 2.82 coal in a 28” proof. 39 went 3k

I'd start at 32.0 grains add half grain increments working up to the mid 2600's, then load 150 of them knowing that somewhere around 100-150rnds in you will likely gain velocity and what shot good before that may not shoot as good after the change. Some folks I know have been OOHing and AAHing about the mid to low 2700's but they are using N150.

Berger 135 LRHT @ 2.805”, 39.0gr H4350 (various primers) = 2820-2850fps from 27” Brux 1:7.5tw. Still seeing linear velocity trends above that, so I’d consider it a mildly warm load. Been up to 2880, but don’t need to be there for this rifle. I am also using the Blackjack spec reamer with 0.131” FB, for reference.

Just ordered a 24” Fluted Sendero for NRL Hunter, and need to make PF with that so I will push a little harder to get to the 2820fps minimum needed. I want to run Alpha brass in this barrel, mainly to help keep it from being interchanged. Does anyone have any comparison between Alpha & Lapua brass (6.5x47L necked down)? I may try Varget for this purpose too, Im slightly compressed around 40gr, and may not have enough case capacity to meet PF with H4350.

Does seem like you'd be pushing it a bit to meet PF. I was considering a 6.5x47 tube with the idea of shooting 144s to help reach PF without running too warm in a 24-25" barrel.

Alpha now makes 25x47 Lapua brass. No neck sizing required.

 

[jps24]

What barrel twist rate are you all using? 1:7 ?

 

[Niles Coyote]

1:7.25

 

[Jdavio]

From reading all these replies, I just want to confirm that the tools required (seating and sizing dies in particular) are both the same for 6.4x47 and the 25x47. So theoretically someone could build a gun in each and have everything they need as long as they had the appropriate bushing/expanding mandrel

 

[John Glidewell]

^^^ correct

 

[Jdavio]

I wish I hadn’t asked. Part of me really wants to turn my 6.5creedmoor into 6.5x47 when I need a new barrel and then build out the 25x47 ha

Looking for some recommendations on starting powder weights for the following:

25x47 Lapua, 24" barrel, 1:7.5 twist
135gr Berger LRHT
H4350

I'm looking to get around 2800fps.

Looking at previous posts, what I found was around 39.0gr H4350.

I'd appreciate any input. Thanks.

 

[762 ULTRAMAGA]

I'm looking to pick up the Manson 25x47 reamer and want to verify that a .135 freebore is enough for the 134 eldm or 135 Berger?

My final load was 40.6 H4350 with a 133 Berger. Slightly compressed. Shot really well. 2840 FPS 24”.

 

[JMGlasgow]

I've settled on 39.5gr H4350 with the 135 Berger LRHT, 2.78" COAL. Velocity from my Benchmark 26" barrel is 2820FPS.

 

[762 ULTRAMAGA]

What freebore are you guys running?

 

[JMGlasgow]

.130 Freebore according to the print.

Are you basically seating the bearing surface at the neck shoulder junction?

 

[JMGlasgow]

I'm seating them far enough into the case so that they reliably feed in my 2.8" magazines. I don't really chase the lands, I just find a load at a length that works and shoot it. This one is .5 moa for five shots.

Honestly this is a very forgiving bullet and cartridge combo. I've only shot the Bergers and 6.5x47 Lapua cases necked down. Every powder and primer combo I've tried has been accurate. I can't reliably shoot any better.

Who's got the deeeeets on when berger 135gr LRHT will be in stock?

 

[JMGlasgow]

No clue. I stocked up when I had the chance.

The .130-.135” FB reamers keep the Boat Tail junction ahead of the neck/shoulder junction in the case. Blackjack specifically designed the reamers that way. Manson, PTG, JGS, etc were all contracted to make reamers for them to distribute to gunsmiths and customers when the bullets went live. Just ask your reamer maker of choice for the latest blackjack spec reamer and you will be in business. The Blackjack Ace 131 XL was the longest .257 bullet of anything ever offered in this class and it cleared the N/S junction well before jam.

Right on man thanks

My go to load is 36.4 gr varget with Alpha brass and 135gr hybrids. 2759 fps and SDs under 5. This is a ten shot group. I have shot several 3-4 shot groups with this load under .25”. It’s a little slow compared to what I see others posting but I am happy with the consistency.

Hi Guys,

could someone who has the 135 Berger 25 Cal please measure something for me ?
I need them to put it in GRT, which is a Software like Quickload, so i could run some calculations.

What i´m looking for is the Diameter at the Start and the End of the Boat Tail, length is mentioned in the Berger Specs.

If someone would let me now these two, that would be great

 

[jps24]

Anyone have experience / data with the Hornady 134gr ELD-M bullets? How well they perform, etc

 

[jps24]

Alpha Munitions brass is in stock now

 

[bbyars]

Drank the koolaid and starting a new build, CRB barrel on order, Dies picked up on the PX. Im really interested to see if/when the new 138 atips become available if they are going to be worth the $$$. Ive seen the new "aeromatch" start to ship but Otherwise ill probably stock up on the 131smk.

What are these new bullets? I got a few of those CRB blanks and 500 Peterson cases in 6.5x47. still debating dies and reloading method. Put an interest pre-order in with ingenuity precision.

Foundation called and told me that my stock is almost ready. Wow! I am excited.

So. Tell me about these bullets and your build?

That is nice. How full does the case get with that much vargay?

I was reading about comparable powders and am tempted to try n150/160/550. Alongside a few other name brands of similar "range".

For target loads, it may be more viable in some circumstances. Save the faster powders for hunting type loads.

 

[bbyars]

I just ordered everything this week so I won’t really have any news til around 2weeks from now

 

[bbyars]

Don’t know anyone that has hands on but paper puts them above bergers….just curious if the extra $10-20 a box is gonna be worth it. But supposedly they are going to be bulk packaging as well to cut some costs as well.

I dunno if the chase of .33 to .34 or .35 is worth it? I know Sierra is now selling the 131ace directly as the 131 smk. It is not the best price, but.. I know those things shoot.

I bought a few of the 134gr(?) Hornady bullets. A box of 100(50?). I have not gotten any berger 135's.

Think I will just try the load data from blackjack and get rounds down range.

What type of dies did you get?

 

[bbyars]

Bought a used SAC x47 die but had full intentions of buying a redding type S for sizing. Also bought a LE Wilson arbor style seater die for 6.5x47.

I have been debating on reloading setup. Initially, I had thought to use a Harvey hand deprime. Mec press with a fl bushing die for sizing and an arbor press for seating. However... That is a lot of investment.

Contemplating just getting a conversion set of Hornady LnL bushings, the mec press and buying a set of whidden dies.. mostly because I will be shooting more like PRS/NRL and actual hunting.

I am thinking a 3d printed primer catch, a universal decapper and the whidden dies would probably get me there when annealing and using quality reloading components/practices. In mind was an ad fx120i scale with some form of automation and one of those pcps or whatever diebody priming systems are called.

However this is due to cost vs return on initial investment. Then goes the rabbit hole of wet tumble vs dry media. *Sigh*

 

[Quietguy88]

@Fat Dark Earth That was shot numbers 31-61 through the barrel.

Jumping forward now

I took 33.0gr of n150 with the 135gr hybrids to a match last Sunday first pic was before the match minus the cold clean bore... second pic will be after 110 rnds were fired. Temperature from beginning to end was in increase of about 20 degrees. And the barrel had just under 180 rounds on it at the start of the day... also, this is with Virgin brass. So I expect sd to tighten up on the next firing.View attachment 8386048View attachment 8386049

How do you like the n150? I have been considering it. Which brand brass are you using and how much powder can you get into the case usably?

I picked up 500 cases of Peterson stamped 6.5x47.

Thank you very much for all the information you have shared so far in this thread.

My 25x47 Lapua just showed up 2 days ago and I managed to get out yesterday. Loaded a random load of rl16 to just break it in. First 3 shots out of the new rifle

Took it too 740 yards and second group at distance

Performed some ladders today and picked a node to test and got these results

So far loving this caliber
