I like to load a bit hotter than Roman by about 2 grains. That is is with either H414SL10 (most constent surplus powder ever made available, right along with 4831) or W760.
I use the Hornady 140gn, SST Interlock for terminal performance.
Every rifle is an entity unto itself. Roman's load, along with mine is with a powder that isn't commonly available anymore. H414SL10, is slightly slower than W760/H414. It was offered by Higginson's. It is a commercial factory powder that was developed for consistencey and was one of the early extreme range powders that showed a lot of promise. To my knowledge, none of the commercial loaders use it anymore as there are other powders available that equal it and cover a wider range of cartridges.
W760 or H414 along with Rx19 or one of the 4350 powders is a very good choice. I like to use magnum primers with ball powders.
I won't tell you not to go lighter than 140 gn bullets but if you want an accurate bullet that will be adequate for everything from bears to elk and moose, without having to resight your rifle between weight changes, it's just about the most versatile bullet weight available.
Each rifle is an entity unto itself. What may be considered a max load in one rifle is just fine in another. Same goes for accuracy.
The thing about 7mms, is that they seem to like slower powders at just about any reasonable velocity, until you get into the magnums. Then they get fussier and want to loaded near max.
The 7-08 is a great all around cartridge. It is on par with the 308Win, 7.65Mauser, 303Brit, 30-06 etc, when they are loaded to similar pressures and bullet weights with similar ballistic coefficients.
Whichever load you decide on, use some discretion and fine tune it to your rifle. Just try to keep things in perspective though. A few tenths of a grain one way or the other in a case loaded for a hunting rifle won't make any noticeable difference in accuracy anywhere, other than your own mind. Unless you are loading a match grade chamber, using off the shelf hunting bullets, groups that measure anywhere under 1 1/2 inches, are fine for shots out to 400 yards. Very few people get a chance to shoot at an animal that far away or think it's a lot further than that.
