Berger 185 Juggernauts

[Liven The Dream]

Just looking for some feed back.

New Rifle .308 Ft/R 30" 1-10 Brux Full Bore Chamber.

Peterson SP Palma Brass CCI 450 Varget 41gr, Average Vol 2609 with Wolf SR Mag Primers Average 2616 .

I am just wondering is this the Velocity or close to what most are running ?

Thanks for your feed back ,

Don,
I am getting more with a different reamer, Winchester brass and 45gr. Varget. About .020 jump. Gilkes-Ross action. How that translates to your setup???

Most people run the 185s over 2700. Most in the 2750 range. Usually have a .170 freebore though. Im not sure how fast the fullbore will allow.

 

[jsthntn247]

should be a node around 2650 and another around 2725-2740 and 1 more even higher if your an Aussie. Peterson's has less capacity so you will probably be using less powder than folks running Lapua. Also as mentioned your freebore is allot shorter so you won't be able to hit the high nodes but should be able to find a good load in the 2700-2750 range.

I will give it a shot for the 2700 + Range .

If you have a long freebore and you're seating them long, you can go way higher on the charge. Mine shoots great at 44.7 of Varget jammed about 5 thou into the lands. QuickLOAD is your friend when loading to non-standard OALs.

My accuracy load with the Juggs is 43.5g H4895, 210M primers and Lapua brass. Averaging 2715 fps

I am very happy with the performance of my rifle with the Berger 185 Jugs, getting 2730 fps. I have tried them at 2500 to 2600 range and did not care for the performance until I crossed 2700. Don't know if this is normal. But it works for me.

Varget 42.9gr
Lapua Winchester Brass
CCI BR-2 Primers
Rem 700
30", 5 gr, 1:10 twist Benchmark barrel
Freebore 0.110"
0.015" off the lands
0.001 Neck tension

I saw the op's comment on "full bore chamber". PT&G produce a 2011 full bore chamber reamer. It has a freebore of .050". If this is the reamer used, that is too short. As mentioned earlier it should be about .170" to allow more room for powder.

That's how I read the OP's post too. If so, its freebore is designed for the 155gn Sierra MK and is far too short for the 185 Juggernaut.

A favourite UK load in a suitably throated barrel is Lapua Palma brass, the SR magnum primer of the user's choice, Viht N150 for MVs varying between 2,825 and 2,875 fps. However, we rarely have to worry about temperature issues here - although this summer is proving to be the exception that proves the rule. (Most of our more serious FTR competitors have upgraded now to the Berger 200.20X, still using Palma brass and N150.)

Brux are "fast" barrels. 2600 is VERY slow regardless of the barrel. I shoot 2750-2775 out of a 30 inch non brux barrel.

The two .308 Brux barrels I had in the past were very accurate but slow. Both were 10 twist 4 groove 30 inch heavy palma contour barrels. I couldn't run the node everyone else was running with 185 juggernauts at the time with Varget/H4895 (2730-2770). I had to run them around 2660 ish. If I went over 2700 I had sticky bolt etc. They were deadly accurate at 2660 though.

Hi Don, all our Juggernaut barrels end up in the 2750 to 2800 range with a 30 to 32 inch barrel using 43.5 grains or so of H4895. Might end up a little slower with Varget, but I'd expect your load to be in the 44 grain area....at least with Lapua small primer brass. Our freebore is .170....get someone with a unithroater to extend your freebore.

Thanks Scott,
Got close to 2700 with 42.5 Varget . Loading today will also try H4895 .
Hope to get to a small Match on 14th July ????

See you there! Devon will be shooting Juggs at 2800

You know how get me going .

Ohhhhh, sorry thought you were going to Raton. Well, maybe we will see you in Raton this fall?

 

[memilanuk]

Don, see if J. Benjamin has a UniThroater. Or find someone with a 2013 US FTR team reamer, and have them run that in. You really want/need a longer throat to run those Juggernauts at competitive velocities; otherwise you might as well go back to B155.5BTs @ 3k.

Peterson SRP has about 3gr less 0.5 gr water capacity than Lapua Palma, so plan accordingly. You are running a short chamber and smaller brass. I had a similar chamber once. Shooting Juggs (before they were called that) I blew primers in WW brass at 43.5gr in the heat. Everyone here is quoting loads for ~170 freebores.

That said you should be able to run them at 2750 to 2775 and find a node.

Wow! That's a lot! QuickLOAD says + 10,000 psi PMax on 43gn VarGet.

Are you sure of that? I have a measured fireformed capacity range of 1.5gn water between the smallest internal capacity and the largest of those I've used - Lapua, Winchester, and 1980s era Norma 160gn weight brass - a very thin-walled light case that has a very high capacity.
