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
