Thanks, John.
Just what I was looking for.

I see mixed reports on Hybrid 100V and Superperformance. Velocity data looks good, but there may be some accuracy issues based on what I've read. Anyone tried these? I tried Hybrid 100V in my previous .257. The potential velocity looked attractive. Accuracy wasn't "there." With H4831 it'd shoot in the .2s for 5 shots with 100 grain ballistic tips. With Hybrid 100V it was more like 2 MOA. Somewhere along the way I managed to burn up a pound of the stuff trying this or that in various guns but I don't really see any need to buy more now that it's gone. Tom Thanks, DF

I wonder how Big Game would work under 110 AB's?

I wonder how Big Game would work under 110 AB's? You would think it would work, burn rate not far from 760/H-414, known performers in the Roberts. I'm going to try Hunter with the 115/117's. DF

Big Game works very well with a wide variety of bullet weights in the .257. My wife used enough BG with the 115 Berger VLD in her NULA Model 20 to get 2900+ fps (can't remember the charge right now) in New Zealand a few years ago to take a bunch of feral goats and a fallow deer.
Hunter also works in the .257 with any bullet weight from 100 grains up. My wife mostly uses 47.0 and the 100-grain TTSX as the all-around load in the NULA. It gets right around 3150 fps and is quite accurate, and she's taken a pile of western big game with it--pronghorns, whitetails, mule deer and one cow elk.
Magnum works too, but in my experience it's best with 115-120 grain bullets. Basically you fill a case with powder and seat a bullet! Velocity is 2900-3000, depending on barrel length and the particular bullet, and accuracy usually very good.

I usually use 4350. Tried some 4831 with 100 gr Sierras this past weekend, worked very well.

It's very hard to go wrong with 40-41 grains of 4350 pushing a 115 grain Partition.
