I've done it. Rifle 280AI,27" lilja,1/9 twist, barrel,160gr AB,Fed 215,IMR-7828. I used Nosler data and their start load was
57.5gr/IMR-7828,Fed 210,2836 fps and max was 61.5gr/IMR-7828,3043fps.
I used F-210 to start with 57.5gr /IMR-7827 @2916fps, When I switch to Fed 215 Primer same load...
Finally got around to chono few loads. Rifle, Rem action, 27" Lilja 1/9 twist barrel, Peterson brass, R-26, long throated. I used Nosler data for 175grABLR. My start load was 55.5/R-26 @2715fps, book load was 2697fps and I worked up to max 59.5/R-26 @2941fps. Its hunting rifle so 3 shot...
As I said I just shot few test loads. I don't chrono those loads and also give me chance adjust seating and decide if I want to use Nosler or Peterson brass. Same with Fed 210m or Fed 215. I load at range so doesn't take much to get good test loads to start with.
Finally got some R-26. I loaded up few test loads for 280AI using 175gr ABLR and was about 1" from existing load @ 100yds. Glad Nolser had some loading data.
Hornady X and Sierra Vl Manual have loading data for 308 Norma mag. I think you can get data on line may have to pay for it. Just looking, Hornady has better selection of powder, both use Norma case.
I have 270Wby and on Rem action with Rock Creek 26" barrel. I've had good luck with 150gr ABLR,IMR-7828. I've got couple boxes 165gr ABLR and need some loading data using IMR-7828, maybe QL.
Thanks

You had only one shot each bull and we shot 5 targets in relays plus we only could use 6x scope at all yardage. I also shot 6ppc match. I think on calm day the 30x47...

If you click on above under 22-250 seater is seater for 30x47. I have neck die and sizer for 30x47
After first firing I ran inside neck reamer. I shot HBR match with 30x47 and the 30x44.

I have 2-30-06's one has 26" barrel other 25 1/2" barrel. Nosler has load of max 56.5 gr/H-4350 with 180gr Partition @2769fps same load in 26" barrel @ 2851fps. I use rifle bull elk tag.
I'm little late. I use .311 bushing and inside is .281. Some may like little more or some like little less. I do clean up necks and most neck thickness varies .001". I measure 4 places on neck so I can get high/low and not using current brass, mine few years old. I had Wilson seater made...
Hornady data for Superformane max is 59.3gr @ 2750fps for all Hornady 180gr/178gr bullets and start is 48.9gr @ 2300fps for 30-06.
Did you do any workup loads or chronograph?
To fine tune you can get expanders from here.

I use bushing and more set up for that and fine tune with those.
K&M also make them

One example I've used frequently is the .300 RUM and .308 Winchester: The .300 RUM has just about twice the powder capacity as the .308, but does NOT produce twice as much velocity--a 100% increase. Instead the velocity increase, with the same bullet at the same pressure, is...
This was done over 24 hr
Dunno either, and can only guess at what Steve's point is about Homer Powley and the 4-to-1 Rule.
For those who aren't familiar with it, the 4-to-1 Rule is that any increase or decrease in the powder capacity of rifle cartridges of the same caliber results in about...
Sure did. I shot HBR with 30x44 and 30x47 both tight necks. I shot BIB 118gr and bullet he no longer makes. It was pretty good match rd and we never shoot pass 300yds. I get on BR site and last few years haven't heard much about either one but nice to see someone enjoy one. Good luck
