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?
Sometimes it just happens like that,I use IMR-4350 in a 243 with similar results. One thing you will find after quiet a few years on the reloading bench is that fastest is not alway the most accurate.
Depending on your intended targets it want notice a couple 100 fps less MV. I guess it depends on what your looking for in a load. Speed and accuracy doesn't always go hand in hand sometimes you can get both sometimes not.
Good group if you like trying other powder in the 308 try some Reloader #15,it's what the US military uses in there 308 sniper ammo.
I just mentioned that this one wasn't fast enough because I am trying to develop a load that works up close and at long distances (up to 800 yards). The velocity on this load is only around 2350 (as per Sierra's manual). I hit on another accuracy node around 2575 that I am going to play around with. This group surprised me though because it was the first, and things don't just work like that, normally anyways.
you get lucky sometimes. enjoy it and make a note of the load for future use...
