The IMR Web Site shows to start at 43 and work up to 45, but at 45, it's a compressed load. I've had decent luck with 39.5 under a 168 SMK, and there seems to be another node around 42.5. I was using NATO brass so 42.5 grains was up around 2833-2847 FPS out of a 30" 1:12 in 90 degree heat.

I have been using 42.5 grains of IMR 4064 in new production PMC cases with 168 AMAX. These cases are much thicker than others and similar to NATO without the primer crimp. Worked up from 41.5 grains to 43 grains, I hit a node right at 42.5. At 43 grains groups opened up but no visible pressure signs. I am sticking with 42.5 for now; especially since case fill is close to 100% and I have not cronied this load yet.

Concerning the .308 178 grain Hornady Match: I tried and like them, so bought 800. Rifle is a Savage Precision Carbine, 20" 5R 1:11.25 twist. I started low and worked up to Hodgdon's max recommended for 175 and 180 grain bullets, 45.0 grain of Varget and am getting no signs of excessive pressure. All my shooting so far has been on cool days, 60 degrees or less. Brass is Lapua, primer is CCI BR-2, COAL is 2.770. Chronograph average for 20 test loads was 2740 fps and drop tests have confirmed that.

Can someone give me the book min./max. for the 185 juggernauts with IMR 4064? Only saw one load running that combo and he was running 43.5. I'm running it out of a DTA 22", any other load data would be appreciated as well. Thanks.

Berger Book says for 185 grain bullets (juggernauts are listed) and IMR 4064:
Start Load: 37.0
Approximate Start Velocity: 2307 fps
Max Load: 41.0
Approximate Max Velocity: 2532 fps
Approximate Fill Ratio: 103%
This is from a 24" barrel and Berger lists the COAL as 2.810" but yours will probably be slightly different. They list the 185 Juggernauts BC as:
G1 BC - 0.560
G7 BC - 0.283
Suggest 1 in 12" twist or faster

I actually got out yesterday to test H4895/155cc. I loaded up an OCW test from 43.9-46.1 in .3g increments. Found a lights out load at 45.8g. Shot a single hole .119" group. 46.1g was right behind it with a slightly larger hole measuring .327".

2.8" OAL (mag length)
Lapua brass
CCI 250 primers (large rifle magnum)

I got this load from George from GAP off of the GAP-10 thread from the old boards. If I remember correctly, he suggested 42.5 grains of Varget or Reloader 15 for 175 grain bullets loaded to mag length (2.8" OAL). Remember, this is for a gas gun.

I've shot H-4895 in my 22" GAP 10 with the 155 CC's. With 44.0 grains, I'm getting avg 2819 FPS with goood accuracy. I've gone up to 45.0 grains in my bolt guns, but haven't chrono'ed those. I think you'll find a good load for the 155's somewhere between 43-45 grains of H-4895.
