SAVAGE LRPV 6BR--NEED A LITTLE HELP

[dusterdave173]

I picked up a new Savage LRPV in 6BR Norma- 8 twist-ordered some 108 ELDM and some 87 Vmax but when bullets got here I got to checking and boy the throat seems short--the 108 is crammed way down in the case at touch--I am not even going to load any of those--the 87 is stuffed in there pretty good too.
So......what bullets should I try--no matter what I have done with the 87 Vmax they just do Not shoot well--I quit on them
I wanted to use this rifle for two things--a long range prairie dog buster--so varmint style bullet and I wanted to use it for long range target playing---and my local club has a factory stock rifle class at 100 yards so that is what I want to attack first--so if I can get a 100 yard load that will zing and a good prairie dog load for 600 and out I will be happy

I was so excited to get a 6BR and start experiencing the legend--but those 87 Vmax AIN"T cutting it

Thanks guys!

Sounds like you have a short range 100/200/300 yard BR chamber with that short throat. Pick up some 68's and you should be good out to 300 for tack driving. A little farther for varmints and find something a little heavier for long range. The Sierra 95s seem to have a good rep!

The only 68's I seem to be able to find are the Barnes Match burners--If they will work I am good--I love Bergers like the rest of you but ...none to be had

That short throat is a GOOD THING. And you didn't even have to ask for it.

You will be surprised at how fast the throat wears, to the point that you can't reach the lands.
I start out with the lightest bullets I can get my hands on, somewhere in the 40/45 gr. range. Load to a .010 jam and go heavier as the throat wears.
So far, I'am up to 60 now and still shooting bug holes.
Had one barrel, not requested but had a deep throat and could get nowhere close to the lands, Offed it to someone that wanted to shoot heavies. Ordered up a short throat and we both ended up happy.
You could get a short throat chambered barrel and stash the long throat till you need it. You may be surprised how soon that may be.

Might be a good idea to check where the lands are so you'll know where to seat the bullets?? They DO have tools for that. Once you know that, you can watch the throat grow longer.

Try some 58g Vmax or the Speer 70g TNT's

I helped my Neice's husband with a Savage LRPV in 6BR that I gave him, it also has an 8-twist factory barrel. That rifle loves the Hornady 87grn V-Max bullets with Varget powder. He is somewhat new to reloading so I made the attached drawing to help him before handing off the rifle back to him. I did sort the 87grn V-Max bullets.

The Berger 95 VLD would be a great choice for long range steel or targets. Requires a short throat like you have and a very, very accurate bullet. Good luck.

No tooling required. Only a dummy round or two.

 

[Tommie]

Before you give up on the 87 VMax - have you tried OAL that has the bullet touching or engraved into the lands? Usually secant ogive bullets don’t like freebore or jump.

 

[NorCalMikie]

No tooling required. Only a dummy round or two.

All my loads are INTO the lands .010. What I've found is, into the lands will show no pressure signs. That exact same load with a "jump to the" lands WILL show pressure.
And when you start changing things, you ONLY change ONE THING AT A TIME or, you end up chasing your tail.
With a dummy round, find the lands, write that measurement down and refer to it often. That OAL will tell you when the throat starts getting longer and why your "special load" went south.

When the throat gets longer its very easy to keep in tune.....with a tuner. All thats reqiuired. I have started out as much as .050 in with both 6ppc snd 6brx. Only ever jumped one barrel in my life...... and I am old.

 

[Hammer]

you ONLY change ONE THING AT A TIME

That's no fun at all.

If you can't change at least thirty things at a time, how can you have any fun ?

 

[J.d. Popkes]

Lots of interesting information on this thread. Throat erodes quickly on a BR. In the lands making less pressure than jumping. Short freebore in an 8 twist.

Following closely

 

[NorCalMikie]

8 twist, zero free bore, no turn neck. Mid range loads so your brass will last.
And ALWAYS leave yourself some "wiggle room" with your loads so you don't have to beat the bolt open.
Start with the lightest bullets you can get your hands on, (40/45) stuffed into the lands and go heavier as the throat wears, and it WILL. 20 to 25 reloads and the brass is STILL going strong with snug primer pockets.

 

[Flyshooter]

Yes, a zero free bore is awesome.......despite or contrary to what is often believed as an absolute, you can shoot heavys in a short free bore.

I have personally chambered a couple of 8 twist barrels (krieger & brux) in 6BR zero free bore. Both tubes shot little tiny groups at 100 yards with 65grn-107grn bullets.

Now your probably not going to able to hit the upper “node” with the heavy bullets. However the accuracy at 600 was fantastic no problem pounding the 4” plate at 600, actually hammering the 3” spinner at 600 was quite easy as the groups were around 1 1/2 inches in the calm.

Now if you just want to shoot 600, then I’d use a 104 free bore. The difference being more powder space with reduced inititial pressure. Meaning your primer pockets stay tight while realizing a few hundred more FPS, accuracy will be about the same......of course in the wind that couple hundred feet per second shows up at 600 with high b.c. projectiles..........No one can deny that.......well no one I shoot with, unless the “long throater” misses and the “short throater” doesn’t, then the heckling can be a little onerous to say the least, wow tough crowd some days......”no sir, he’s not shooting a scoped 870 Remington Improved cyclinder”.....”I know the gentlemen, and he favors the Winchester model 12”........

When I had my 6br Norma built I took your advice and had a Manson reamer ground with zero FB. Great results. Any experience with a zero FB in a 6PPC to pass along. .

If you have a GOOD gunsmith local, take it to him to have it throated out.

 

[dusterdave173]

Yep THANKS for all the ideas
I was disappointed because I dreamed of shooting heavy bullets and living that 6BR dream but..
I finally got the 87's shooting--I had to really shorten up my OAL--wound up at 2.115 which is .015 back from the lands and swapping from Varget to N135 was the ticket!
Pix is of 87 Vmax at 2.130--you can see where it was in the throat or lands?
Got them grouping decent at 100--3 shot groups in photos--No I did not show the other 5 groups that were bigger( you guys know--bigger lol) I think I can tinker with the load now and get it really steady
87 VM, 450 primer, Peterson brass, 28.8-29.2g of N135, OAL 2.115, 2898 FPS at 28.9 g es/sd was 9 and 3!
I stopped at 29.2 but will try more on next test--primers looked perfect, brass looked happy
This Savage rifle was built during Covid years--maybe they were slapping whatever they had together? It has a Short free bore for sure. I can throat it but figured try some more bullets like 58Vmax, some 68's and just see what happens--IF I can get the 87Vmax shooting this good most of the time I will shut up and shoot

The Hornady depth checker ( Lewis Tool) just acted different in this chamber--It acted weird--it was very hard to tell where touch was so I marked bullets and seated at different depths until I got it to just mark the bullet --then called that jamb or touch or --a starting point at least

 

[Dgd6mm]

This month I'll be getting back to the 87vmax's in my 6br with VV135.
Hopefully at the same time I'll try some 108eldm's also. I have plenty of 5 different powders to try...one at a time.

@dusterdave173 here you a link to some bullets. You can thank me later berger can't compete with these. https://www.jokerammunition.com/
