What powder and charge weight are you running to get those types of velocities? Sounds like a hot ass load
What powder and charge weight are you running to get those types of velocities? Sounds like a hot ass load
Sounds real hot. I'm slinging 140 Hybrids at 2800 with 37g Varget SD3 and .25moa out of a 26" Bartlein.
That’s what I was thinking too, I’m at 2760 with the RDF’s and 37.3 g varget. Same load with the Hybrids got me right at 2800. I’m running a 24” Bartlein. 2900 fps with the RDF’s out of a 24 inch tube is insane speed unless something like RL17 is used and that’s still pushing it
2900FPS with 140s? how many loads you get on your brass? i ran up to 38.1 grains of varget and only had 2814 and that was a VERY hot load.
Trick is the h4350. 41.8g for 2836fps this is my pet load. The next higher node was 42.6g no pressure signs 2913fps. Haven’t had to pull any brass from the lineup yet, and I have fewer than 200 pieces. Not sure how many reloads, I stopped counting. I just aneal every three firings or so. Lapua Brass is the cat’s ass! BTW, obviously have to use a drop tube to fit it all in and the 140 is just ever so slightly compressed when seated at 2.165 BTO
no way i could get that much 4350 in mine...but my reamer only has .100 freebore....funny thing is i sent 130 and 140g berger hybrid dummies in to JGS and had the reamer/chamber built around the bergers and this barrel wont shoot either one very well but it shoots the 140g ELD-Ms so well i bought 3000 of them.
41.8g H4350 is a hot load. I tested up to 41.1g with H4350 which was 2817 SD 4 .358" group but had a sticky bolt. Thats in a 26" Bartlein.

My last 6.5x47 was in a Bartlein and chambered by short action customs, he and I could not get anything to shoot very fast out of it without seeing pressure. This rifle was chambered by patriot valley arms and is built on a Mullerworks barrel. Night and day difference. Not only do I not have a sticky bolt with this load but I am constantly running through full 10 round mags at matches. At the time I was having it built I asked Josh to chamber it for the 130 hybrid.
Got some numbers on my 36.6 varget under 140eld m

That was lapua on the 5th firing with NO case prep, cci no41 primers(those gold hard cupped AR15 primers), 28" Savage prefit barrel. .289 bushing full length sized every reload.
About to try some 4451 out the new 18" 6.5x47 with 123gr scenars. I went to 41gr. If it shoots decent (1/2 MOA) and gives me the speed i'm hoping for i'll likely run it until hunting season ends. If the velocity isn't there might look to 2000MR or RL16.
Anyone ran 4451 or H4350 rather in a shorter config? I know it's burn rate seems a bit counter productive for shorter barrel lengths but i can't help but think it's will provide moderate results.

IMR 8208 may work good with those lighter pills and short barrel too. It’s more temp stable than 2000 mr, and faster burning than the 4451 and would probably work good in that set up.
8208 temp stable? I know i could punch the ticket with RL17, no question i can get the speed i want out of it. But i also want temp stability so my DOPE isn't changing that drastically.
8208 is very very temp stable, don’t know if it will produce the velocity RL17 or PP2000 will because those two powders are crazy in the velocity category but it’s a very accurate and stable powder that does produce higher velocities than other average temp stable powders do. It’s too fast for the heavies in 6.5x47 but should work pretty good with the lighter pills and short barrel. If I ran lighter weight pills in mine it would be the first powder is try.
From left to right 39.5-40.5gr of 4451 with 123gr scenars .010 off the lands. Only 4 shots in the first group, other than the flier it looks pretty decent. SD was 3.3 so probably going to run with it for a bit. Second group was 2550ish with an SD of 8.2. Last group i rushed and shot fast because i was running out of daylight truth be told i should've let the can cool as the mirage was killing me.

About to try some 2000MR. Went from 40.5-43gr in 1/2gr increments and am hoping not to run into pressure signs but we shall see tomorrow.
Yup 123s, i have some 140s actually but haven't even bothered with them out of such a short barrel.
Been playing around with the lite weight pills, the 47’ makes a great coyote and varmint shooter.

Geno what barrel length?
Here are the results from 2000mr stopped at 41.5 as i figured i was pushing pressure and jumped out of the node. 40.5 is the top left that gave me an SD of 3.0 I'll have to look back to see the environmentals. 41.5 got me to 2887avg but with an SD of 28.3.
Got some 123gr ELD-Ms in going to load some this weekend over 8208 and see how it does. Been told to try varget as well which i have a ton of though i'm almost positive i'd be pushing 37+ grains to reach that kind of speed in such a short package. I've been debating on just moving up to a 130 and shooting for 2700. More energy across the board.

Well one way or another i'm going to get 2800 with a temp stable powder...funny now kind of regretting not getting 130 ELD-Ms. At 2700 they're more viable than the 123s past 600yds. For 600yd hunting they're both pretty similar. Yes that is a throwback H4895
Here's some 130gr OCW's for you to compare. 130 ELD-M or 130 Hybrid with Varget is probably your best bet and 2700+ shouldnt be a problem.
Shot RL16 today using the .2gr increment method looking for flat spots. Went from 40.0-42.8 in .2gr increments. No pressure signs as far as i could tell. Which QL acts like you can't get enough RL16 in the case to spike pressure. These are .010 off the lands, loaded with 205s/205m i use them basically interchangeably depending on which is readily available to me at the time. All 15 shots are next to the D, didn't change out to a fresh target because it's 28F here.
Will likely move to 130s after i run out of 123s as i still think 2750 with 130s over RL16 or Varget for that matter will be more viable. That said if i didn't have to settle powder so much with RL16 i'd probably run 42.7 and call it a day at 2900 or so. Probably still need to compare as 42.1 should give me nearly 2850.
Here are the results. 18" barrel with the omega on the end. 28F 30.50inHg 66% humidity.

I have a few friends that have put a lot of time into finding balance of speed and bullet weight. They all ended up settling on the 130jlk. Might want to give them a look. Most are using Varget
Yeah I’ve been told varget is the way to go. But i feel like I’d have to push it to get the speeds i want. Based on my experience with 4166. Contrary to that i can’t seem to get enough RL16 In the case.
Shot the rest of the 2000mr with it being 45F here. Still seemed to hold up fine. The second attachment is 42.1gr of RL16 gave me an SD of 8 out of 5 shots. Mostly threw them straight from chargemaster.

If you have a tight firing pin; the brass can take the Varget
Anyone tried the 100 grain Berger bullets with the 6.5 x 47? Part of me feels this is a back door to the 6 x 47 without a new barrel!
I don't think i do with the bighorn at least if we're to assume that's based on primer flow i get primer flow with pretty much everything i've tried thus far. With the Tempest i've pushed to 37.8 with 4166 but got pressure signs on both it and 37.6
You might have problems with the top loads of Varget then... mine is a win70 and they are notoriously sloppy around the pin. I'm blanking every 15-20th. Have a new pin spring on the way to see it I can get away with just that. If not, off to be bushed.
Here's a shot of my LabRadar after shooting 28rds the other day for a seating depth test. So thats 8 foulers than 5 shot groups of 4 different base to ogive measurements. 5.8 SD.

Pretty impressive fella
As I stated those 28 shots were a seating depth test. So varry8ng from touching lands to .02 off...
I understood that. Barrel length and a COAL range like 2.780-2.800 would get guys in the right area though. Just trying to clarify for someone looking to find a load similar to yours
So I got around to load development for 2 projectiles... Nosler 140 RDF, which I only did the first stage to find a velocity node, and then switched to the Berger Hybrid 130 AR OTM.
24" MPA build, Surefire 300SPS. Magnetospeed V3, and I used Labradar side by side with the V3 for the 140 RDF.
For the RDF 140, 37.0 to 37.5 grains of Varget gave me 2801, 2795, 2808, and 2803fps so I would have explored 37.3 grains.
For the Berger Hybrid 130: 37.8 gr Varget, CCI 450, .030" off the lands. 3 shot ES: 3, SD: 1.4
This gave me 2925fps and .312" for the group I shot, and I've never shot for groups, so I was happy. I'll try to post some pics
I tried 10, 20, 30, and 40 thousandths off, with .030" off the best, followed by .020"(.435" group SD: 9), then .040" off (.562" group SD: 3.1). .010" off was a .8" 5 shot group with an SD of 1
Now I have 50 rounds loaded to try at distance, hopefully I'll get results out to 1,000 yards. So far, I'm very excited about my first try at load development.

Following. I just sent my specs to PVA for my Nucleus barrel.
Running an OCW with 120 Scenar L-.020 off, reformed, annealed, inside/outside reamed, 300 Savage cases fired 4-5x, Varget and BR2 primers. 24” Krieger on Stiller Predator. Trying to make sense of the string of 10 round velocity variation and determine nodes, and reading steps that don’t seem to have continuity.
37.0-2924. 37.1-2918. 37.2-2947. 37.3-2958
37.4-2942. 37.5-2951. 37.6-2975. 37.7-2966
37.8-2970. 37.9-2994
Appears 37.2-37.6 could be close, but velocity variation has me uncertain if I’m already above where I should be. Primers a bit flat at edge but not out of line. Need to bush for smaller firing pin. Could use some of the assembled guidance here.

Are those 1 shot at each charge weight?? If so, you can't put much weight into velocity. Pick center of node and move on to testing seating depth. For real velocity numbers you need to shoot 15-20rds..
I would pick 37.3-37.4 and move on.
I would pick 37.3-37.4 and move on.
Was trying to see if there was continuity to POI and velocity, hence one shot on each target but last. Will proceed as you’ve noted and advise. Thx.

Shot both loads to 800 yards this weekend with great results.
140 load took 6 Mils and the 130 load took 5.4 Mils.
Measuring off the steel both loads printed about 3”-4” groups on steel at 800.
Looking at trying some 123 scenars next and probably some 130 eld-m.

So my load has dramatically dropped speed. Been running 36.2gr of 4166 which had me at 2815fps. It was 2735fps before the F-class match this weekend and i just chrono'd the last 11 of that batch today and had an avg of 2747fps. SD of 6 with both so pretty happy about that. I'm hoping it was just a bad batch of powder, or the results of me leaving that particular pound out in my chargemaster for two weeks.
If not i think i'm going to try RL16 with the longer barrel. Given the results i'm getting out of my 18" 6.5x47 i think 2800-2850 wouldn't be hard.

Ran RL16 out of the short 6.5x47 today 8 shots in with 42.1gr of RL16 no issues all of a sudden 9 and 10 are sticky as hell, both showing stout pressure signs. I let the gun rest. Take the can off and fire nearly another 50rds without a single hiccup. Which goes back to my condensation theory or maybe my omega just inherently causes issue on that gun. I don't get it. I do load development exclusively with the can. Yes it was colder when i developed the load originally but it averaged 2840 during the winter. Average today was 2839. No unusual velocity jumps of any kind.

I finally found a node for the 130gr hybrid with varget and it the best two shot group i've ever printed, then it got to my head and whiffed the third shot.
Chorono results are solid though. 37.6gr of Varget out of 3 shots gave me an SD of 1 and then 3 more shots of 37.8gr gave me an over all SD between the two of 4.1 out of 6 shots. Not my best day accuracy wise, 15mph wind was killing me and i'm having a hard time adjust to the Huber.
Also had one case that is about to have case head separation. What's a realistic number of firings for 6.5x47 without annealing? I think i'm at 12 or so now on 2nd hand brass.
