Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
Thanks Rick, I just got my 9.3 and some 250 Accubonds... Need to load some up and see what the deal is!
60 grs Varget!
I am hoping I can get by with RL15 Vern. I have MOUNDS of it and no Varget... I am going to fight the urge to buy Varget for this one. I don't use it in anything else.
Attached is a nice group using John's max of 60.5 of Varget with the 250 NAB. I shot this group just this morning. But I got 90 FPS less than John did with his. He has written that Varget varies quite a bit lot-to-lot and he has seen up to 2 grains different required to get the same velocity/pressure from one lot of Varget to the other. I'm also attaching the chart of his original 9.3x62 data. Cheers, Rex
EDIT: I was wrong - it was Re15 that John saw the lot to lot differences with, not Varget. He wrote that Varget was quite consistent. Sorry for that error.
I stopped there. 3 shots under an inch is expected with that load.
Overall length is 3.367”. Nothing specific in regards to the long, tapered throat. It just feeds well there in my old Pre-64 that started life as a 30-06.

That’s very similar to mine with 250s. I get a few more feet per second but I’m using magnum primers.
I get less with the 286 however. 66 grains Big Game gives me 2470 FPS.
Also like mine and most others I’ve heard about, the 286 partition is more accurate than the boattail Accubond. I’ve heard theories about jumping bullets and resultant accuracy with boattail bullets, and since we can’t get close to the throat in most 9.3 x 62s… I wonder.
