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...

Tanner

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.

I'm in the around 45-grains of Varget club.

Thanks gents.

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.

Amazing........ 308's pushing 300wm speeds!

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.

Ya think.....

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.

My 308 loves the 155s and 46.5 gr of 4064. Work up to it. The only other powder that came close for accuracy was R-15 but was slower. I get 2930 out of a 23" barrel using Lapua brass, and 210 primers.

Powder Charge?

Who is "We"?

you could hear pin drop.......

Not hardly. 48.6gr in this lot of MR.

Who is "We"?

48.6 grs is just above the case/shoulder junction, what's the OAL?

Tanner, TAC is good with 155's too, if you have any of that. If you want to try some let me know, I have a big jug. Or Varget for that matter.

2.930 COAL. AI mags.

Who did the pressure testing?

And what were the pressure #'s

Got quiet....

"Pressure tested" as in "I've fired them in my rifle and it hasn't blown up yet"

Or

"We hooked up a piezo and it registered at 63K"

Big difference between the two...

No free rides, thats for sure.

Tanner, report back to us when you shoot the rifle. I'm interested to hear how it does.

Probably wise on his part to skirt around the pressure ??"s

It's a stupid question. 48.5gr is max for a 180 with a MUCH longer bearing surface then the Juggernaut. This lot at 48.6gr with a Juggernaut, this case and primer loaded to 2.930 has been tested by a third party using propper pressure testing equipment to be within Saami spec. If you can't read sign, I can't help you.


I clearly said that the 2,900fps load was not within Saami spec, though it's not ridiculous either.








A group of people.

Only stupid to you..... your the one that said it was pressure tested I was just asking for a little extra info, you seem to be a little irritated by a couple easy questions that were asked by others as well,
I don't believe you would have come back to answer the ?'s if I did not mention you were skirting the issue's, your the one that painted yourself into a corner and your still being pretty vague, "me reading sign" but it's your story and can tell it anyway you want!

I really don't think it matters very much. FormD shoots a fugging ton and seems to hit what he is pointing his rifle at a large majority of the time. If he was going to blow a gun up, I believe it would've already happened.

I wish the newest QL had 2000-MR,

175 SMK vs 185 Berger...

Question- why use the jauggernaught vs the Hunter version? BC looks similar on their web. What am I missing?

Because there capable of unbelievable velocities.....

I'll take the 155 gr Scenar at 2900fps out of my 22 inch barreled GAP...

I guaranty 155's @ 2900 is a bunch safer than 185's @ 2900......
