Hi Tango,
For the 100+gr. bullets I would consider the H4831. Although 4350 is also really good powder for most stuff a 25-06 will do.
--- Winchester Cases
--- Winchester LR Primers
--- Berger 115gr Hunting VLD
--- H4831 @ 48 Starting up to around 52ish max. The 2 I reload for (not mine) seem to like 51.4gr of H4831. Remember Always Work Up Slowly!!!!
This load chrono's out right about 2890, in the 2 rifles i load for, and is utterly deadly out to 500 yards. (min 2000fps and 1000lb of energy retained)
There are not a whole lot of combinations that will honestly beat it, and be anywhere remotely as pleasant to shoot. Certainly that 7mag will, but it is a fire breathing beast! Oh, if it is not a savage W / Accu-trigger...DON'T Do It!!!!
just a word to the wise...some of the older savage / stevens were utterly sadistic to shoot! BTW, I shoot a 375 H&H quite comfortably, and a 375 Ruger, as well as a Winchester Stainless Stalker 300wm shooting 208gr Amax using H1000 .... I am telling you some of those old savage / stevens Pre-Accu-Trigger were down right Hurtful!
Shoot it first, before you buy.
That being said, the accu-trigger era for savage pretty much turned the company around on a dime. I own an Accu-trigger Savage 111 in custom chambered 6.5x55 BJAI and it shoots very well. Even when it was brand new as a 30-06 it shot real nice.
Shoot well,
Gary
