.308 loads with 169 SMK

I'm running them in my M14. I cleaned a 600 yard target last week and shot 1.2 MOA at 600 yards for 11 shots. 100-6X, 110-7X if you count the sighter. I shot six X's in a row before the wind blew me out of the X-ring and into the 10-ring. I managed to hold left and bring it back into the X-ring.

I'm running 42.6 grains of IMR-4064 with Remington 9-1/2 primers and military brass. Muzzle velocity out of a 22" barrel was 2630 FPS. The target indicates a SD of 12. You'll have to play with your seating depth according to your chamber print. I'm running a match chamber and I'm running longer than mag length. It's over 2.850".

Since the vintage sniper match I shoot in is single-feed only, I'm able to get away with running a longer than mag length load.

Here's a 300 yard target with a 15 MPH wind.

They have been shooting well at 2630-2640 fps in my new to me M1A with N135. My biggest issue is holding elevation at 600 yards with a sight post and 63 year old eyes. That and remembering the knob directions are backwards from my Warners. :)

Tell us about that rifle
 
It's an excellent bullet! Like Tony I've also shot them in my match built M14. Bartlein Barrel of course. Dave Ferrante did the build work. This barrel is an 1-11 twist and 5R rifling.

According to my twist calcs they need a 1-11 min twist.

Also been shooting them in my clone M40A1 build. Also has 5R rifling but it's a 1-10 twist. Pic attached of the rifle. This is to spec... 25" finish length barrel. My chamber reamer set for the 169SMK. At 43.0 of Varget and .015" off the lands with a CCI BR2 2692fps avg with SD's of 6.9 with LC match brass.
