VVN560 powder info for 6X47 Lapua(or other calibers)?

[CT10ring]

Hello, shooters,

I "found" 4 lbs of VV N560 recently. After a period several years with no shooting, I'm getting
back into it again and reloading. I think I had this powder for a 22-243 1/8 twist rifle, but ended up
liking RL-22 loads for it, and never used...

I'd like to try in a 6X47 Lapua 1/8 twist - Surgeon action,
Krieger heavy barrel 24", with 105 Amax, or similar (Pdog gun)...VV N550 is a great powder for this
rifle @ 37.5g.

Any info on this "high energy" powder...? maybe similar to H4350? info appreciated.

Thank you-

Howdy !

Some years ago I contacted Kaltron-Pettibone about potential applications for VV560, after having found no good accuracy load for my wildcat .22-35 Remington ( .224" calibre 24" 1-14 5-groove ).

They told me the high energy series powders worked best under the heavier/heaviest bullets in each caliber; and cited their testing w/ .308Win. Their info seemed valid, as I was trying VV560 under 55gr .224's

I also tried VV560 under 88gr Bergers in my DCEEP 6 wildcat ( 51.2gr H2O capacity ).
And again, could not find accuracy I sought; noting the 88s are a mid-weight bullet for 6mm.
That was two-for-two.

I DK if that helps any ?


With regards,
357Mag

Hey, Thanks, not so encouraging but that's still good info.
I'm going to give it a try, heavy bullets for caliber best, maybe. 105's - I have plenty in 6mm.

thanks!

I used to use it in my first 6.5 x 284. It is capable of producing extreme accuracy coupled with extreme velocity. However, there is 1 property of this powder that I do not like. This powder is every bit as "hot" if you will as VV N540 and N550. It will eat the throat out of any "overbore" where a high rate of sustained fire is required. However, if used as hunting powder (not for prairie dogs) it should prove to be exceptional! It's burn rate is nearly equal of RL-22..

Dots, Agree Have used it for max loads in 25-06, 6.5-06, 270, 300. Heats a bbl as quick or quicker than rl22. Excellent velocity, but nodes narrow

 

[CT10ring]

Understood; thank you. I will certainly give it a shot (ha!) or 5. RL-22 similar burn rate, copy.
I'm curious if any 6x47 loads exist. I'm a fan of VV N550.
I'm the rare guy who shoots not as much in a PD town as is possible.
If I do, it's with an AR + a can.

I found a load with VV160 in my 6x47 Lapua. Tried 115 Berger and 105 Berger Hybrids. I found my VV160 to be a little slower. I know you got VV560 but I could check my notes if you are interested in a starting point.

 

[CT10ring]

Sure thanks, I have Berger 105g Hybrids that came w/a barrelled action I just bought.

 

[Zero333]

Out of curiosity...

What velocity are you getting with the 37.5 gr VV-560 load ???

I ask because Quickload shows velocity around 2,600 fps, which would make it a very mild load and would extend your barrel life compared to near max loads.

CT, with you on the n-550. Extremely good accuracy and top velocity.

 

[CT10ring]

Zero333,
I must admit, I have never used a chrono, so I am busted on fps.

New rifle/caliber or rifle -- I usually shoot 4-6 loads, 5 rds each - 3 ranges of powder weights, 3 seating depths, 1 powder (hopefully) at 100 yds.

Then at 200 yds. Then PD shooting later...reconfirm zero and shoot 250-600+ yds. minute of PD at 500 yds is still
3-4"

In the case of 37.5g VV N550, I loaded that weight and it shot extremely well. done. .015 off lands

I did a 1 month PD shooting trip in WY, MT, ND in Oct. Took quite a few rifles.

6x47L, 22-243 + 6BR my favorites.
here's a pic of the 6BR. Stiller Predator, single shot, Krieger 1/14 twist, no turn .271 nk.
Greg Tannel built 10 yrs ago.

Also 6.5X284, but that feels like cheating - shooting pdogs...

I shoot 58, 65 + 75g Vmaxes, bipod mostly and it is just shocking how accurate the 6BR is.

Got both based solely on reading this site and the info + loads here.
What great info available & shooters posting - shooters who have "forgotten" more about LR shooting than I will ever know.

 

[Zero333]

Nice rifles !

I personally prefer lower velocity for loads that will be shot 600m and under. Less recoil, longer barrel life, and the target can't tell the difference anyways.

Mind you even if Quickload is off by 100 fps, that would mean you're still 300 fps short of max velocity with the 105's in the 6x47L with a 24" stick.

Ballistic difference between 2,700 fps and 3,000 fps at 500 yards is roughly 12.5" drop (2.5 ish moa difference), and about 2.5"ish wind drift.

For a pdog hunter, this ballistic difference means ??? (I'm not a pdog sniper so I have no idea)

Barrel life will be longer at 2,700 fps but I don't know how much longer.

Realistically speaking, you would need a load at 3,000 fps that is every bit as accurate as your current load and shoot them both in the field to have a true comparison in ballistic performance difference. The difference in the ballistic program is not much, but not little either, all depending on the range being shot.

Hello Zero,

Great info + thx. I found a nice, like new 6 X 47L barreled action that I put into stock, etc.
Surgeon 591 & Krieger 1/8 tw. Should be a good one. twins now...

I'm going to try varying (more) amounts of powder on this build. Sounds like I could easily add
1-3 grains. I check primers, pockets, bolt lift, etc.

Quickload - app?

Here's a pic.

VV560 and RL22 are the go to powders in my Bartlein barreled 7mm rem mag. VV560 prints tiny groups with the Berger 175 elite hunter bullet.

 

[Zero333]

Quickload is a program for reloaders. It's very in depth but easy to use.

It's not cheap and needs updating (that cost extra) to get new powders, bullets and cartridges into the database.

I'd like to try in a 6X47 Lapua 1/8 twist - Surgeon action,
Krieger heavy barrel 24", with 105 Amax, or similar

With all due respect, VVN-560 is too slow for your standard loads in the 6x47 Lapua using the 105 AMAX bullets seated at the 2.700" length. Now, if you moved up to the 115 grain VLD then your pressure and velocity will start to make a little more sense. This is still using the seating at 2.700" OAL. Not the best mind you but in an area which can be considered moderate performance.

The better performance I've found has been with Ramshot Hunter, Norma URP and Re-16. Re-16 was the best of the three in overall velocity and accuracy.

 

[CT10ring]

hey, that's good to know. re 6X47L -- I loaded some 88g Bergers & 105 Amaxes w VV N-550, got tiny groups (at 100 yds), and loaded for a PD trip (my "sport"), and didn't use a chrono. Not sure where I got that idea/load, that was 5 yrs ago. I used the same "leftover" ammo on a recent trip. I had 115g DTACs at that time, but
opted for a varmint round.

Certainly glad to try better suited powders. I'm semi-retired, so I have more time for these important matters . I may even start turning necks. and using a chrono, which I have...

I'll get some RE-16. I have RL 15, 17, 19, 22, 25.

Any other info, send it.
There is no published major powder manufacturer data on this round so far as I know.

I read that H4350 is a go to powder but I can't seem to find it anywhere for sale...
kinda why I'm using VV powders also. They can be had.

thx.

If it was me, I'd try it. In my 2nd 6x47 barrel, I ran 38.5 gr of VV N550, moly 105 hybrid at 3100 fps. There was still a lot of room in the case and if I had not had 30lbs of N 550, N560 would have been my choice. Not apples to apples, still running about the same combo in an xc, 38.9gr, moly hybrid at 3110fps. Quickload says 42.5 gr of usable case cap at 2.700" Oal, 43.5gr capacity at 2.800" Oal, and 2.8" way under mag length.
An added bonus for you here would be if you were running a .236" groove barrel as you'd be generating even more pressure.

 

[CT10ring]

cool, trying RL-17, RL-22, VV N550 & 88g Berger, 105 Berger Hybrid, and 87g Vmax (seems to shoot in every 6mm I've owned). Then VV N560. Seems that even if I was getting accurate groups prior, I'm giving up 300- 400 fps with slower powders? Krieger bbl, I have no idea if .236"... This is a new to me rifle (barreled action) I picked up, very similar to another I own. Identical actually. Bob Greene built #1 + SAC built #2. info & opinions appreciated. into the breech. Ha.
