I have tried a number of powders with the 123 Scenar, and so far, my rifle seems to like either Tac, or W748 the best. The issue I have is that these powders are more temperature sensitive than I like.
I'm fairly conservative, and always prefer accuracy over velocity. The best accuracy for me seems to be with 30.3 of W748 (max is 30.5 with the info I have). In my 19.5 inch barreled rifle, this generates about 2540 FPS during summer months. In winter, velocity drops to around 2460, but accuracy seems to still be pretty good.
I would like to know what other people are finding that gives both good accuracy, and isn't as temperature sensitive.
A friend of mine has used 8280 and reports very good accuracy, but his velocity indicates the load is hotter than I want to use. Well, there is that, and he recently had a bolt lug break...I prefer a more conservative loading so my equipment will (hopefully) last longer.
The less temperature sensitive powders like Varget and 8280 don't seem to work as well with the smaller case of the Grendel.
What powders are you all using to get good accuracy, reasonable velocity, that isn't too temperature sensitive?
