No can't quit go that long I checked today and 2.910 at the lands with 180. With 162 is 2.950 at the lands.Is your barrel throated for a 2.950" oal with the 180gr Eld-M? You may not be able to go that long otherwise. Another .150" of powder space could change that list a bit though. I'd say those are basically starting loads as well. I doubt you will see any pressure signs until you get above 60,000psi...
That's decent speed. What kind of accuracy did you get?Well I finally got out to try it. Loaded to 2.94 COAL and used Ramshot Hunter. 46.1 grains was highest I went and was 2550 fps. Accuracy node was 45.5 grains at 2520 fps. This is with Mcgowen 8 twist 22" barrel.
I have always had an inkling to find a Kimber Montana or Classic in an 84L (270-30/06) and rebarrel to a 7mm Mauser with an 8 twist. Being as that action would really let a guy seat a long 175/180 class bullet out pretty long it would seem to be an excellent performer and nice to carry when a fella was wandering around for the day.Not quite apples and oranges but the 7x57 with 175s played hell with Teddy Roosevelt and the rough riders as well as killing every thing in Africa up to and including elephant. Personally I saw one shoot through two caribou at about 200 yards. Going heavy and going long sure seems to be the trend, i‘d be curious to see how it stacks up against the 162 class bullets in real life.
Saw your velocity numbers how did it shoot?
Ive yet to play with the 175 in my #1 but with reloader 26 55 grains was about all I could get in the case, it was just about spilling out.
what would reloader 17 look like.
