6x47 Lapua Varmint Built!

[Jwhip]

Several months ago I went searching around forums looking for load data with lighter bullets for a 6x47 Lapua I planned to build. Well it’s built now. 10 twist Shilen select match on a savage target action. Glass bedded the barreled action into a Richards rosewood laminate thumb hole stock. I’m currently working on some loads. 1/3 ish moa from the 88gr high bc Berger varmint bullets traveling 3050fps no pressure signs. I’m thinking on sticking with that load, but both 64 and 80 gr Berger loads Are in the works. I do have some old 75 gr sierras I will try as well. The 64 gr has showed good promise but I need to get the velocity up a bit. I’ll continue to post my data on this thread if anyone is interested.

That looks like fun, and it’s a shooter too!
I’m shooting 107’s out of a eight twist, it’s my favorite rifle to shoot.

Been looking for info on light bulllets in 6x47L too. I'm looking to build a point and shoot to as far as I can coyote rifle. Already have dies and am pretty stuck on this cartridge as I've had excellent success with the 6.5x47L in a precision rifle; plenty of old brass to neck down and not care about loosing too.

Thanks for posting, most info out there is for long, heavy high BC bullets.

Looks great, I have a couple of 6 x 47 Lapua's one a hunting rifle and one a heavy varmint rig. Both rifles shoot the 105 Berger VLD hunting bullets great. I use H4350 & N140 with those bullets. The heavy varmint rig I also shoot 70gr Sierra Bltzkings with Reloader 17. I would say you definitely have room for more speed. I'm getting 3075 fps with the 105gr Berger's and 3650 fps with the 70gr Blitzking's.

Awesome! That’s good to know. I’ll try to push those 88s faster

Nice Looking rifle and a great shooter!

Here is a link to a thread I started a long time ago about load testing my 6X47L on a Savage Target Action with a PacNor 10 twist barrel. https://forum.accurateshooter.com/threads/6x47-lapua-loads.2381201/

Great! Thank you!

About 15 years back I bought a 6 x 47 from Shehane that was built on a Borden action. It was a 1- 8 Twist and loved the 105 Bergers. I shot this group with it at 500 yds. that measured @ .991 after cal. deduction. I should have never sold it.

New personal best group coming from the 64gr BR Column Bergers. I wanted to get the speed up more, but I figured there’s no need to mess with that round. It’s a target bullet so that’s what I’ll keep it as. Working on a hotter load for 75 gr Varmint round now.

Have you tried any other powders?

Nice shooting I shot Berger 88's in my 1/8 twist 6X47, but after 20-30 rounds, they come apart somewhere downrange. Good call on the 1/10 twist. VV N550 is a great powder for 6X47, too.

May I ask what

freebore/leade is your reamer?

I had Dan Dowling spin me up a 6x47L back around 2005. It was crazy accurate but at first I could not get the velocity to stabilize. Every time I chronographed it I got a different velocity range. I tried all kinds of primers and powders, but found the solution one day while at the range.

In the used brass bucket I spotted some clean looking 22-250 cases, so I grabbed up a hand full of them, went home expanded the necks and ran them through my 6x47 sizing die.

Now I could test the difference between small primers and large primers. The results were definitive.

Well put it this way, I tossed all my small primer Lapua brass in the trash and started making my cases from 6XC brass because it was the closest in size to the 6x47.

If you look at what the pros use, (PRS) there is not one guy near the top who uses a 6x47 and its my understanding that guys think it is fussy and inconsistent. Welcome to the club boys, but the large primer brass did the trick for me.

You boys down south might not notice as much of a problem in the warm weather as I did up here in an Ontario January, but that gun with large primers sure put some gold on the wall.

If you are ok with how yours shoots, that's fine, but if you feel experimental some day, test large primers over a chronograph and I'd be curious to hear what you find, especially over a wide range of temperatures.

BTW, I don't remember my freebore, but I was running 115s at 3000 FPS. If I recall it was a 1:8 twist polygonal barrel from Gary Schneider. I was getting groups around 1/8th MOA at 100 yards. Velocity spread was the lowest I ever saw. I had to turn my chronograph off and on between shots because it kept showing the same number and I thought it didn't catch the shot.

Thanks for sharing this!
If you don’t mind what is your process for forming the 6x47L out of the 6XC brass?

Yes! I would like to know also.

It's really quite simple, just run 6XC brass through the 6x47L sizing die and length trim.

That's pretty much all there is to it.

All you'd be doing is bumping back the shoulder about 0.050", so it's not going to collapse the side wall like a 22-250 case will. 22-250 cases need a light load to blow the side wall back out after sizing but not with the 6XC.

Of coarse you probably want to anneal after you size it, if you are into annealing, but you don't have to.

That’s great to know!
I noticed Peterson and Alpha both have the XC, do you have a preference? I like the way the 6.5x47 Lapua brass fits my .272 chamber necked down now in the 6x47.

I always used Norma brass. Never did any testing with any others.

I always neck turn my brass, but if you don't, then make sure you double check the neck diameter of loaded rounds to make sure that you don't end up with extra fat necks.

The easy way is to use a Redding neck sizing bushing as a go gage. In your case, if 0.272 fits without force, you're ok, but you might want to use something a bit smaller.
