I've never shot any Vihtvouri powders and thought it might be worth a try. Anybody have quikload so they can run the numbers? Looking at the 275gr Xpb im guessing loads will be mag length.
That's a valid concern with N120. According to QuickLoad, which though it may take some tweaking to get it accurately predicting velocities for a given load, it definitely knows how to calculate volumes. It says that a 100% fill with N120 is too little, other than for a designated light load. You start to get into the sweet zone with N120 at 111% fill. Probably even more given QuickLoad's proclivity for coming in a little conservative.

AND... My thought is, thou I love the Vihtyouri powders, I use them on rare occasions. I find if I can't go to the local 7-11 and buy components, I make do with what is actually, readily available. Some of those Vihtyouri powders are very difficult to find, even using the web.
275gr-300gr is where the line breaks, depending on your reloading practices, 296 may be a bit fast and 1680 a bit slow. 300gr bullets and up, 1680 rules.
For my money, 1680 produces loads that are only slightly slower in speeds, than 296, but a have far lower pressures, when using the 275xpb's.
The XPB's are so accurate and retains it's Taylor Numbers (TKO), so well, that I predict, they will be the bullet that kills Elk, Moose, the Big Bears, yea even deer, this fall, in excess of 400yds.. I heard, and don't quote me, as heard it from Commander Faschisto, that the Texas Sheep Dawg, has been maintaining a bait pile at 2 miles, and plans to kill a Coyote at that range,with his beloved 450 Bushmaster, go figure.
I'll have to check my notes, but I'll post a starting load for those 275's, tomorrow I hope. In the mean time, you might like to look at the 200gr XPB's, they two are quite pointed and are truly a great Long-Range bullet. I've even gotten them to 3000fps! They'll bounce a deer all over the field..
