I'm working through a load development for my .308 Winchester with 175 grain Matchkings. The final powder option was IMR 4350, and today was my first time shooting this powder.
The first group I shot was this...
That's the best load I have ever just stumbled on before. I'm trying other charges too, because this one has too low of a velocity for my liking. But still, it's impressive. Does anybody else shoot .308 winchester with IMR 4350?
