Just got my boys 47 out yesterday after a quick and rough load work up.

120 amax
cci 450
short throated .070" freebore
2.589" COAL
37.9gr Varget
2926fps

44moa to 1200. Put the last 3 rounds into 4" at that distance to finish up the afternoon. 6moa of wind

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.
40.0: 2693
40.2: 2716
40.4: 2710
40.6: 2740
40.8: 2735
41.0: 2777
41.2: 2788
41.4: 2807
41.6: 2812
41.8: 2827
42.0: 2841
42.2: 2842
42.4: 2866
42.6: 2896
42.8: 2895

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
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.

PVA 26" Rock Creek Button Prefit
140 ELD-M
37.2g Varget
2xLapua
CCI 450
2831
SD 5.8

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.
