25x47 Lapua load data
- Thread starter JMGlasgow
- Start date
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.
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.
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
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.

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”.
I've settled on 39.5gr H4350 with the 135 Berger LRHT, 2.78" COAL. Velocity from my Benchmark 26" barrel is 2820FPS.
Sweet
Are you basically seating the bearing surface at the neck shoulder junction?
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.

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.
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

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.
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?
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*
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

Has anyone shot the Manson .135 FB and Compared against the Alpha .180 FB? Most of the PRS pros are moving towards the .180 and just curious if there was that noticable of change?
I am liking them, with a healthy jump (.06 with my measurements), Varget, 2720fps. Silly small groups.. on par with the 135s.
I haven’t been able to shoot them far enough to get a trued bc tho.
Does anyone have a BC for the 134eldms? Is Hornady close with .325?
Just 600 and 800 looks like I’m gonna have to up the bc over what AB says. I think it’s gonna be around .320-.335 range. When barrel was new the .315 matched, now trending a tenth or two high. I only gained 50 fps over the initial 200-300 rounds.
