Yup, I know this is a Nosler forum but sometimes you just stray a bit. Anyone have a Sierra manual they’d screenshot and post for the .308 Win using a 165 Sierra Game King bullet?
 
Thank you, very much appreciated. I figured I’d start with some H4895 today and see how they shoot. It’s a Tikka compact with a 20 inch barrel so I’m not expecting max speeds, just hoping for some decent accuracy.
 
So I ran some H4895 today. 42.5 grains yielded a .63 inch group for 4 shots. 43 had 3 shots just a smidge tighter but the 4th shot opened up a bit and ran 40 fps faster for that final shot. Going back this weekend with some more at 43 and some at 43.5.

Looks like you might be on to something.

There you go. Sounds good.
 
IMG_2844.jpegIMG_2831.jpeg…and I’m done. 43 grains held 4 shots right at an inch, 43.5 opened up a bit and printed 1.5 inches higher. I cut my targets up and did an overlay of all my shots with 42, 42.5 and 43 grains. I threw out the farthest 2 shots and 14 hit within 1.2 inches with the different powder charges. I decided to load several more and split the difference using 42.8 and went out to 200 yards. Off the bags 3 shots measured right at 1.5 inches. I did something I rarely do and attached a bipod out of curiosity. Those 3 shots were just a touch lower, I assume due to mounting the gun differently as it’s a taller bipod and I’m more directly behind it, but still grouped at 1.75 inches. Considering the crosshairs probably cover 3/4ths of an inch at 100 and I’m not trying to chase extreme accuracy in a hunting gun, I’m more than happy with this load.
