Has anybody tried this combination? I've got a good amount of IMR-4064 on hand and plan on starting and hopefully stopping there, but I'm just curious on others' results...

Thanks...

Briefly, had Varget seated to mag length and shot well (but, per usual foolishly sold it). IIRC, was Lapua brass and 47gr

Can't help with the IMR powder, but with Varget they shoot real well. Little over 2900 with a 26" barrel IIRC.

Tanner,

Using IMR 4064 with 155's, you'll find a a great node around 46.5grs. Winchester brass. Reduce by .4 grains if using Lake City, or Federal brass. Reduce by .3 grains if using Lapua brass.

I have been running 45'ish grains RL15, Lapua brass and 155 scenars. Haven't chrono'd yet but shooting 1/2-3/4" in my Montana and to the same impact as 150 TTSXs. Haven't tried 4064 yet.

Tanner,

Take a gander at the 185gr Juggernauts. We're running them between 2,800-2,900fps with 2000MR. Whole new world with a 308.

That's fast. What length barrel?

That is fast for a 185 out of a .308. Even the high end for a 30-06. I have not tried 2000MR, CFE223 or any of the other new powders that seem to work well in the 308 Win. I can get 165s over 2900 out of my 26" barreled 308 using Varget.

Most are 24 inch. My 26in comp rifle using LC LR brass is pushing 2,920fps. The same load out of a 22in hunting rifle is over 2,800fps. I was a big user of 155's until these. A Juggernaut at those speeds beats our 300WM's with 190 SMK's.

2800-2900 has gotta be pushing it pretty hard on pressure. Nosler has data for their 190 with the same powder. Showing 2624 fps in a 24" barrel. Alliant's 2000 MR data shows 2724 fps with a 175 Matchking in a 24" barrel. These new powders aren't magic.

BTW, who is the "We" in the "We're running them" statement?

Hell, I need to ditch my 7WSM and 162's, I was only averaging 3050 out of a 24" barrel but using another 20 gr's of powder.

QL predicts 2738 with the 185 over CF223, not MR2000 but the powder with the highest velocity for the 308.

Pushing pressure from 62K to 69K gets 2813.

When I worked up a load for 155gr Scenars, this charge is what provided the best accuracy for me. Shot a five shot group with it just the other day that measured in the .3s. Velocity is 2870ish.

Of course it's pushing them. Well at least the 2,900fps loads are. 2,784fps isn't. They have been pressure tested and I am perfectly fine with the results. Others may vary.

I'm at just over 1,500 Juggernauts in the last 2 months or so. I highly doubt that I will ever shoot 155's again.

4064, '15, Vargay, 748 and 4895 will all work just fine with the 155 Scenar. I'd use whatever you've got on hand. I went with 748 for this year's muley load.

Who is doing the pressure testing?
And what are the exact pressures for a 185 @2920?

I tried them in my montana and couldn't get them to group like I wanted. I will be working with 180 Sciroccos and 185 juggernauts this winter to see if I can find some magic there as I have both rl-17 and 2000-mr on hand.
