I don't know if you've tried but the Winchester LRM have the lowest SD in my 300WSM, 6.5 WSM and there's a couple of guys that gave up on the Feds and CCI shooting 338 Edge and 6.5-280 out my way.
Yes, very true ... and shooting other stuff too along with home projects completely unrelated to shooting. I'm hoping to buy a used gas-powered concrete mixer this weekend and then there'll be more projects.
You must have some kind of "spidey sense" because I was at Proof Research yesterday afternoon discussing my 6.5 PRC project. Kelly told me that the current "best" twist rate is 1:7.5 which is what they use and yet I had barrels made with a 1:8 twist based on Horndady's recommendation. She also mentioned that a tight chamber with "lots" of freebore helps. I don't think that the twist difference would be a deal breaker but I still haven't managed to get consistently good results. I was thinking about trying different torque values at the barrel receiver interface to see if it makes a difference. Overall this project hasn't gone that well and I really don't know why. I was expecting greatness from this rifle/cartridge combination but so far all I see is mediocrity.

I'm just curious what your expectations are/were for the rifle.
Do you think that the folks at Hornady had your needs or application in mind when designing the 6.5 PRC or the 143 gr. ELDX? What were their standards? Objectives and application? Did they meet those objectives with factory systems?I forgot mention, the good folks at Proof Research very kindly offered to take a look at the rifle and see if they had any input on why it's not shooting the way I hoped. They might need to put me under the microscope! I like to solve my own problems so I'm hesitant to take the rifle to them since it would be an admission of failure on my part. I tried to check the barrel twist but got very inconsistent results but the vendor assures me that they are 1:8. I'm not done with this project yet and will try to get back on it and figure out the annealing process for the Hornady brass. I'll also try using GM215M rather than GM210M primers in case that helps any.

still fighting with mine as well. I'm going looking for some factory fodder today hopefully.Still 6.5 PRC at the moment, but it would take 10 minutes to swap out the barrel for the original 300 WSM or the .308 Win that I tried. It's been on the back burner for a while now but I'll get back on it at some point. I need to try a different powder and work up some AccuBond LR handloads. I have a bunch of the 142gr ABLR bullets to try and I don't think the 1:8 twist rate is a problem at all.

I appreciate you gents sharing your experience with this one. Really makes me think maybe I ought to just stay in the leopard camp after all when I build my 6.5 screamer....still fighting with mine as well. I'm going looking for some factory fodder today hopefully.
I can break 3k with good accuracy from mine, but not with anything resembling book data.

I’d love to hear how them 142’s do for you!Still 6.5 PRC at the moment, but it would take 10 minutes to swap out the barrel for the original 300 WSM or the .308 Win that I tried.

Yep, that really is a recurring theme for many of us. I still need to get a Remington 700 Alaskan Ti project wrapped up so that I can sell it.
I'll definitely report back on any load development for the ABLRs. I've been working for months on my driveway in preparation for 9,000+ sq.ft. of asphalt. I have a small Kubota tractor with a loader and backhoe so it takes a lot of time and effort to move many cubic yards of dirt and rocks, some the size of an armchair! The paving company were at my house last Friday to grade, fill and compact, and yesterday they were here to lay asphalt. It's all done now so hopefully I can get back on some load development in between sifting dirt and back-filling where necessary, building retaining walls, extending the barn, etc.
Im having a hard time finding a case gauge with a shell holder right now, any suggestions, i want to use it in my Lee case conditioning kit to resize brass if neccary, im still looking, is not the prc a little longer than creedmor and grendal.
Any news you can share about the 142 ablr’s?
Sounds like good gear! Can’t wait to hear about it!!!Nothing to report at the moment but hopefully this spring I'll be able to work up a load using the ABLRs. I placed an order with Redding in January for a powder measure, 6.5 PRC dies and 7mm-08 AI dies. The check was cashed a couple of days ago so I assume that they'll be shipping the order out soon.

Nothing at the moment. The rifle has sat for months and other projects have taken precedence, not all of them firearms related.
