What kind of rifle will you be shooting it in? Also watching for load data wave

41 gr IMR 4895 w/ 168 Sierra or Hornady. I shot thousands of these loads in a Model 70 Winchester Target rifle and aSpringfield Armory M1A NM rifle.

Doug, do you have any velocity data?

I shot the 168 gr. with 41.5 gr. of IMR 4895. I'll see if I can get velocity data if Doug does not have any. Mine shot a really nice group at 300 yards from my M1A with iron sights.

I've seen 41.5 a lot on the Internet. That must be a standard load like 43.0 Varget and a 175.

I believe my load is 2650 fps in a 24" barrel. That is from memory and I think it is right,

If I can get 2650 accurately, I'll be happy with that.

Thanks to both of you!

You're welcome. I'll still try and chrono it at some point. Maybe at the M&G, the way my schedule is (full - very little free time).

Mr Bowser is right. 41.0 grains under a 168 MatchKing with a GMM gives +/- 2650 in a 24" 40X for me depending on the weather. You can also use up to 41.5 grains, depending on your gun. I also like the same load under a 165 GameKing. Great hunting load for your long shooter.

My Ruger Scout didnt like 165s and 4895 at any charge. Never tried that powder with 168s. Best groups i got with 165s was about 2" at 100. With 168s and RE15 i was about 1/2-3/4"

42.5 grains 4895 with 2.80" OAL will shoot sub-moa groups out of a 700 SPS Varmint with 168gr SMK's and 165gr SGK's.

No one has mentioned what barrel twist yet...and it matters

I have a couple 308 bolts jbp and for some reason they just don't like 168's that well...I've always heard that 169 gr was da bomb in a 308....but have not found the magic yet...They are tight as can be at 100....but open up for me enough at 300 to where it aint a keeper load...so I've pretty much abandoned 168's for the moment....I shoot em for foulers

My twist's are 1:10 and 1:12

Both of mine are 10's. I've got a bunch of them and need a use for them. I can always load them for my Garand.

I have shot thousands of Sierra 168's in bolt guns and the M1A. The M1A had a 1:12 twist and the bolt guns have had 1:12, 1:11 and 1:10 twist. I have used Federal 210M primers and Winchester large rifle primers. I have used Lake City military match brass and Winchester commercial brass. My chronograph data was lost in a move.....as I recall the M1-A liked 40.5 grains of IMR 4894 and did fine with 41.0. The bolt guns did fine with 40.5 all the way to 42.0......from all that shooting I think the load Doug mentioned is the one that would do it every time ------- twist does make a little difference with the 168 but you would need a real good rifle/shooter combination to see it out to 300 meters. However, case capacity is important. Generally the rifles preformed with a slightly lower charge in the LC cases as compared to the commercial cases. LC cases are generally a little thicker. The 168's were designed and tested to be the king-kong bullet from a 308 @ 300 meters. They will do OK out to 600 but the 168's give their best performance in a 308 out to 300 meters.

Setpoint ammo shows the following recipe for the Ruger Scout(1:10 twist) out to 300yds.


BULLET TYPE:
Sierra 175gr MK
CASE:
Lapua 308 WIN
POWDER TYPE:
Varget
POWDER WEIGHT:
44.4 gr.
COAL:
2.800"

I'm thinking about ordering a box to try mine out with a scope borrowed from a buddy. But at $38.00 it seems kinda pricy, then again, I'm not used to buying match grade ammo.

If anyone uses this recipe, let me/us know the results.
