I'd still shoot some 5-10 shot groups to verify but would have a hard time believing that rifle would start throwing big groups. I hope to get something close to that.
Spent last night annealing and resizing 7 RM brass. Will trim tonight and load up 175 ABLR, 65 to 70 grains of H1000, and 64-68 of Re26, in 0.5 grain increments to find pressure. Due to mag box constraints, I cant get to L&G with that long pointy bullet. I'll then load 3 at pressure for each powder and see what happens. I'd be tickled if it kept them at an inch on the first go......
Them 7mm, 175 gr ABLR sure look sinister. Driving them at 2900+ should make for good elk medicine.

0.035" of reaching L&G which isn't terrible.
It does have a small spacer, I'd guess ~ 0.150 - no way to get a Mashburn jammed in there.

I also shot the 175 ABLR with 67 gr H1000 and it didn't group as well as the 180 ELDM (just over 1 MOA). All have been seated .020-.025 off rifling. I understand the ABLR likes more jump so will seat deeper and try again. I'm anxious to see what the 180 Scenar will do as well.

Thanks JGray! Please let us know how it goes. I've also gandered at the 180 Scenar - but bought several hundred ABLRs during the SPS sale at less than 1/2 price. Couldn't pass at that price.

Try the Nosler at .080” back from lands or even .10 back. They shoot well for me there.

I have some .284" Berger 190gr Hybrid Target on the way to add to what else I have waiting for the Garmin. And I hope the Garmin shows up soon, I keep buying rifles to compensate for a chronograph being on backorder!

After shooting that group using the ELDM bullets and 65gr R26, I'd call it quits....as long as you can back that up a few times with a cold barrel.

I had a couple hundred 175 ABLR previously and just a got a couple hundred more with that same sale. I'm determined to make them work!

Not looking for anything more - quite satisfied as is. Just want to see what other bullets will do...

ADG brass showed up just as we're packing for a trip to Hawaii. Threw together some H1000 loads with 180 ELDM's and ran out first thing yesterday (had to leave for airport at 2 pm). Hornady data shows max with 180's at 67.4 gr H100 and 2900 fps in a 24" barreled. I shot 64, 65, 66 and 67 gr. Grouping really tightened up at 66 and 67 gr and 2797 and 2830 fps respectively. At 100 yds (I mislabeled as 175 ELDX): ![[Linked Image from i.imgur.com]](https://i.imgur.com/4cjlOSD.jpeg) ![[Linked Image from i.imgur.com]](https://i.imgur.com/Opo8AcQ.jpg) New Arken EPL4 4-16 shot from initial bore sight without touching turrets to achieve zero. No clickers or stiff bolt lift, but very slight ejector marks at 67 gr, but damn this thing wants to shoot! I feel like 67.5 gr is doable and should be 2850'ish in a 22" barrel which jives with Hornady's data in a 24" barrel. Will continue with RL26 in ADG brass in a couple weeks - aloha from the beach  Just finished another range session - went to 67.5 H1000 with the 180 ELDM in new ADG brass. Magnetospeed showed 2872 fps, no visible pressure signs, and this at 100: ![[Linked Image from i.imgur.com]](https://i.imgur.com/KpPdkD4.jpg) Then moved to RL26 with the 180 ELDM in new ADG brass. Magnetospeed showed: 64 gr 2832 fps 65 gr 2849 fps 66 gr 2895 fps 67 gr 2956 fps w/ light ejector marks and just a hint of stiff bolt lift - hardly noticeable. About pissed myself watching the group develop with the 65 gr load ![[Linked Image from i.imgur.com]](https://i.imgur.com/Rl0klSQ.jpg) Best accuracy seems to be around 2850 with both powders, though RL26 is capable of getting 2900-2950 with 1/2 MOA accuracy. Recoil is notably more with RL26 above 64 gr - enough that back of trigger guard is popping my middle finger. I hadn't noticed that previously with the H1000 loads. Another 150 ADG cases arrived today... Dang, that's a shooter! Don't listen to these nuts - "Shoot another one", "shoot cold bore", blah, blah... Cut that group out, fold it carefully and put it in your wallet! Don't shoot another group with that load for a couple months anyway  Seriously, nice rifle. Those ones don't grow on trees. Have you run the factory ELDM load over a chrono with that rifle?

Not the ELDM - just the factory 175 ELDX at 2726.

I'd think if factory is running 2700, it would not be easy to hit 2850 without some unseen signs of pressure. I got 2726 with factory 175 ELDX, and think Beav might have been a little less, but don't recall without going back to his 7 PRC thread. 67 gr H1000 gave me 2830 with the 180 ELDM and the best accuracy I've seen so far. Hornady data lists 67.1 H1000 as max for the 175's and 67.4 as max for the 180 ELDM. Based on my fired cases, I'm fairly confident I can safely get to 2850 in my 22" barrel with the 180 ELDM and H1000. Over 2900 should be safely doable with RL26. Case head on Hornady factory 175 ELDX is .529 before firing and .532 after. ADG with 67 H1000 and 180 ELDM is .530 before and .533 after firing. .003 case head expansion on both. Fired brass comparison: ![[Linked Image from i.imgur.com]](https://i.imgur.com/v6XgxKb.jpg) How many firings? Clickers usually show up around five or six firings with the other PRC cases with SAAMI reamers.

1st firing for both cases. The only clickers I've experienced were on the second firing of ADG brass in my 7 SAUM, and the second firing of Starline brass in a 270 Win. Both of those loads were fine in new brass, so am thinking it's a brass sizing thing.

After a large sample size of over 100 rounds, I am averaging 2880 fps out of a 26" bartlein barrel. My ES is 51 fps.
This is with Hornady factory 175 ELD X loads.
