In load development process, stumbled upon this one

[Gearheadpyro]

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?

As you can see, you don't have to be a "speed freak" to be accurate. Don't mess with a good thing. ;D Just load more ammo.

I'm by no means a speed freak about my loads. I'd much prefer to shoot something a tad slower and have the barrel last that much longer. This load is slow even for me though. My goal with the matchking bullets is to have a load that stays supersonic out to 800 yards or more, due to the fact that I want to get in to long range shooting. I hit another decent accuracy node at a higher charge that I am going to play around with.

That dog will hunt.

Just curious, what kind of velocity are you getting with that load?

With just about the same amount of RL15, (43.2) and 175 SMK's, I get right at 2780.

How far off the lands are you seating them? Looks like a real good load for your rifle.

That was actually just my starting load, so the velocity was very low. Sierra's manual says around 2350, I don't have a chrono to get hard data with.
I have a remington 700 that has one of those fantastic lawyer chambers, so the max OAL for this bullet is around 2.934" with .060" holding it in the cartridge. This load was right at 2.800" (factory recommended OAL). Lots and lots of bullet jump.
