Weather is really good for shooting now. Going to start shooting my 6.5x47 lapua for the first time. I have 100 factory loaded rounds I'm gonna shoot first. then 200 pieces of fresh brass for reloading. I have the following components
Bullets: 130gr Berger AR Hybrid OTM 130gr eld-m 140gr Sierra match kings 136gr Lapua scenar L
Primer: CCI 400 CCI 450 Federal 205m
Powder: CFE 223 Varget H4350 Vihtavuori N150 <- i don;t have any but i see a good deal online so highly considering buying some to try here. I've had great luck with N160 in a 260.
Please suggest a starting combo. I idea here is to commit to shooting at least 500-1000rds the chosen combo. Brass is the only decided part. Truly don't know what to chose. If it matters, it's a Tikka t3 action with a 22" fairly heavy contoured barrel with a brake. Built to be a PRS type rifle. Most shooting will be 600yrds or less.
Varget and H4350 are the go-to's on that round. I run H4350 in mine. I switched to the 130 Hybrid's on my last batch of ammo. For 600 and in, I'd lean towards the 130 grain. I use CCI #450 primers. The 205's are thinner cupped and will pierce much easier. If you have a problem with pierced primers, you will need to send your bolt off to be bushed.
So I went with 130 eldm and Varget for now. The attached pic is a 9 sets of 3-shot loads at 100yds only. 8) is 35.5gr and 9) is 35.8gr. I will certainly try some where in there.
BUT at 2715-2730fps just feels a little slow to me. Heck, my 260 does that with a 147eldm and N160. I have not seen any overpressure signs. The bolt maybe a little harder to lift but not sure if it's just in my head. I'm kind if a wuss when it comes to running hot loads, in general. Still feels like this should be going faster.
A 22" 6.5X47 making 130's go 2715-2730 fps. Nothing wrong with that. It's a new barrel, it's going to speed up. And some barrels are faster than others. There's no way to explain it, but it is a thing.

I'm running a 130 VLD at 2894 fps in a 21"or 22" barrel in my 6.5x47. The 140's I'm running around 2730 fps. There is certainly more room to go up with your 130 ELDM at 2715 fps, if you want. Varget will work fine with the 130's. Your 35.8 grains is below the published max also. I find the 6.5x47 handles pressure very well, better than most cartridges. Depending on your round count on the barrel, you should be able to get up into the 2800+ fps easily.
thanks for the feedback gents. The accuracy so far is amazing. My first purpose built rifle has been great. Easily 0.5 to <1.0moa all day on multiple groups at both 100 and 300yds with factory 136gr ammo.
Currently there have been 127rds through this barrel (Brux i believe). Seems like sacrilege but I am starting out with a Peterson brass. I have some Lapuas I will try next with the same Varget but 130AR hyrbids so this 130eldm load will stay. I think I will push the Lapua version higher. I was expecting like over 2800fps.
I forgot to mention I seated my bullets to approx. 2.675" COAL. Using the hornady tool, the bullet jammed basically right at 2.700". Is it normal to be that short? I've shot the test loads so I know there are no issues. But 2.700" COAL is what i tend to see most often in manuals. The factory ammo was about that and it touched the lands slightly.
One more question, anyone has experience with Vihtavuori N550 and this caliber? Do some christmas spending.
Seating depth and where the ogive makes contact with the rifling depends on what reamer was used. There are 3 common throat lengths in the 6.5x47, basically a short, medium and long throat reamers (I don't recall the exact throat dimensions). But most use the medium reamer, which mine is the medium. COAL is shorter, like arounf 2.7 ish with a 140 grain, which is common.
V N550 is a double base powder and is in the burn rate of H4350. It would be a good powder in this round, especially if you want higher velocity. (All N5xx series powders are double base, where the N1xx series powders are single base powders from VV).

Manuals don't matter, on ammo length. Load for the free bore in YOUR chamber. You found lands at what CBTO? If "even" fits in the mag, seat about .005" deeper in the brass, and start there with powder charge testing.
That is why a whole lot of good loads, in a whole lot of cartridges are well above published maximum. You're not part of SAAMI. You are loading ammo just for you. Your ammo is not going into someone else's rifle.

I can get you kind of close with what you have. I use Lapua Brass (obviously), Federal GM205M Primers, Varget and 140 gr. Berger VLDs at 2818f.p.s. with single digit S.D. . I haven’t used the bullets that you have listed so take my advice with a grain of salt.
Also i had my rifle chambered with a throat just slightly longer than SAAMI ( S&S had a custom reamer for when Stick was still shooting benchrest.) so I could seat the bullet longer and have a hair more powder capacity.
If your rifle has a small firing pin with a bushing you can probably push it harder than the published data (Be careful with this. Every rifle is unique). If not start with around 35 gr. of Varget and carefully work up from there. Try to find the node that gives you the best combination of accuracy, S.D., and velocity. Be on the look out for high pressure signs.
My load is 37.2 gr. Of Varget with the 140gr. VLD and i am able to get better velocity than most Creedmores. Most of my brass is on its fourth reload and i have never seen pressure signs.
thanks for the info Ritter. Have you annealed your brass within these first 4-5 firings?
Just trying to help out.
And yes, I anneal the brass every time. I also load 300-400 round at a time.
I just do it because it’s become a habit for all of the odd stuff I load.
Honestly I wouldn’t worry about annealing the brass for the Lapua. The 6.5 is not very hard on brass and even if you full length resize it, your still not working it very much. Just pay attention to your case length and once you need to trim it is when you might think about annealing it.
