6x47 Lapua build

[ziondogg]

Custom rifle build virgin here. Gonna build a 6x47 lapua for bench rest off a origin action and shoot 105gr bergers. Am i right in choosing a 28" 1-8 twist bull barrel?

Personally I think an 8 twist is great for 105 grain bullets. My barrel is a 26” 8 twist and the Berger 105 Hybrids go downrange at 3060 fps using Varget. Very accurate round for me and easy to find a load for. Enjoy the new build...

I agree, an 8 twist is perfect for your 6 x 47 Lapua. 26" or 28" barrel would be fine.

Thanks fellas......what contour would you recommend?

 

[JBT47]

8 twist at 28”. I would seriously consider a 6 BR based cartridge such as the Dasher or BRA over the 6x47 Lapua for BR shooting.

I chose the 6x47L because of how easily it is to size down 6.5x67L brass.

You may want to do a search about tuning one. 6BR is a no-brainer, JMHO

Ziondogg:
I have an experimental 6x47 Lapua,.100 short, with the neck left full length for 600 BR. Using
RL15 and 4895 and Bart's Gunghnirs. It does well some days in load development but it very temperamental. Best nodes are in BRA territory, so little was gained. Approaching 3050 it is easily doable but not competitive.

Based on results so far I will switch to a BRA.

It aint easy...to do well.

6x47 is a great choice and I have experience with virtually everything. If you need help or have questions feel free to send me a message. I have had 7 of them and all shot well. 8 Twist is what you want and if you are just shooting off the bench I would get a HV contour and cut it at 28”. If you might carry it one day then I would get a rem Varmint contour and cut it at 26”.

My 6x47L is based on a trued Remington 700, with a 26" Bartlein 1-7.5 twist. Rem Varmint contour @ 26". I'm getting close to 3150 with Berger 105 Hybrids, & H-4350...... Love this thing!!!!!! Idaho-45

1-8 with 105's is perfect.

I have a 6-47 along with a few others. I LOVE my 6-47....it is my favorite rifle....just not for serious BR work.

6BR, 6BRA, or even a Dasher. If making brass for the dasher seems like to much work you can always have it custom made by one of the guys on this sight or use a reamer made for the new Norma brass.

You didn't say what kind of BR work........100-300, 600, 1000?

Again...LOVE my 47...just not for BR.

Good luck, and WELCOME,
Tod

I need a lecture because it was tough for me...

Get a set of redding dies with a shoulder bump die and simply run the lubed 6.5 brass into it. You end up with slightly oversized necks which can then be easily finished off with the neck die. Never lost a case and it only took a few min to do 100 cases.

I am going to try that--how do I save a post for future reference??

That one someone else is going to answer.

Also....if you already have a full die set on the shelf you can just buy the bump die seperat. They are cheap.

Also...you should back the die off a coupe of turns....you don't want to actually bump the shoulders.....just squeeze the necks. In fact , I leave a little "false shoulder" (like when making Dasher brass) to make PERFECT brass. I like to feel a litle resistance when closing the bolt.

Tod hit it on the head..... using bump die is the key. A works well when pushing shoulders too. When I do this I move the shoulder first, then neck down, as in making a short.

I had issues with the first batch of 6.5x47L brass I tried necking down. After doing a bit of research here on this sight, I learned that some were using a Redding Body Die for the first step in necking down to 6x47L. After getting one of those dies, & using a "2 step" method, Redding body die first, followed by a quick trip through a Forster FL sizer, & my new 6x47L, beautiful cases are ready for loading!!!! Just my personal experience! Idaho-45

I’ve got the exact same dies in to do the brass forming like yours. New build is not going to be till May so haven’t picked up brass yet.
Okay, I’ve got some questions. Do you screw body die all the way down to touch the shell holder on up-stroke or back it off some like Todd was talking about above?
Should I only form 5 or so new ones first, then shoot them to get fire-form length for a measurement to then only not move the shoulders back to much on rest of the new brass before sizing? I hope that makes sense.

 

[22DASHER]

I skipped the body die all together and just use my 6x47L FL Type S bushing die with NO bushing on the first pass. Then run the brass through again with the appropriate bushing. If the brass chambers fine I would not push the shoulders back at all, no reason to. Brass will then be ready to go after its first firing.
