The right twist for a 6mmBR

[k80skeet]

I am looking at a savage LRPV in 6mmBR they offer twists in 1 in 8 and 1 in 12. I will be shooting this rifle at a 100yards off the bench. It also might be used as a long range ground hog gun on rare ocations. The Question is which twist to buy??? pro's and con's of each.

The 8 twist is more versatile. My first was a 12 and only shot up to 80g bullets. My new 8 shoots 95 bibs and 108 bergers better at 100 than 80s.

I'd go the 12" twist for short range target (<600 yards) and for any groundhog/varminting. The 90-105gr bullets do not expand nor carry the fps to be varmint deadly. I know that folks will tell you that their 8" twist shoots light bullets great but any short range bench rest 'smith will recommend 13.5"-14" twist for competitive accuracy out to 200 yards, 12" allows you to use bullets in the 80gr and down.

k80skeet,

I have a 6 BR in all twist but 9. I like the 12 tw best for varmint hunting. I use a 70 gr Sierria Blitzking and N135, and have one shot kills out to 620yds. Also for benchrest out to 600 yds. Get some 68 and 80 gr benchrest bullets and you will be set.

All my 8 twist rifles will shoot the 80's very well, and the 105 Berger VLD will unglue a coyote varmint out to 560 yards with out a problem....
I for one would hate to be limited to just shooting lightweight bullets with a 12 twist...

Yes, again for the 8 twist, more versatile. My 1-8 Hart does extremely well with the 68 gr. Berger #24411, my favorite "lightweight" bullet, and at the other end, the 95 gr. Berger VLD's and 95 gr. Sierra #1537 also work extremely well, so a wide range of bullet weight selections. My 1-14's are limited to around 70/ 75 gr, and the 1-9.25 is limited to 85 gr. max.

8" twist. As others said, it is more versatile than the 12" twist.

k80skeet,

I reread your question and didn't see that you asked which twist is more versatile. You asked about shooting 100yds off the bench and as a long range ground hog gun on rare occasions- - so the answer is buy the 12" twist it will work much better for your intended purpose.

Later if you want "versatile" for you can get a 1 in 7" twist barrel for lobbing all the bullets, including 115gr, out of your 6mmBR.

I own more 6mm 8" twist barrels then I do 12" but I still believe for your purposes the 12" is the one. No decent bench rest 'smith, barrel or bullet manufacturer would recommend a fast twist for a BR at shorter ranges. Even a 14" twist will shoot competitive and very well to 300 +yards!

I liked the part where he asked about long range ground hogs on rare occasions..
When that rare occasion pops up I want a 8 twist to help out..........
I also liked where he mentioned Pro's & Cons of either one

Preacher,
I always enjoy reading your posts, and too liked the part where he asked about long range ground hogs on rare occasions. The 70gr - 80gr bullets are the ticket for ground hogs. My experience is that the while the 90, 95 and 105 Bergers shoot great in proper twist they don't expand much less blowup to stop a ground hog from becoming a crawler. The 105 A-Max is the best of the heavies doesn't rip a prairie dog at all and only sometimes a ground hog. The 70 gr Sierra BlitzKing and 80 grain Berger shoot great and kill well at both short and long range. If you can find a box of 87 gr V-Max that shoot well at (test at longer distances) grab that lot number for spares.

I guess I will clairfy what I am really looking for which wouol shoot the smallest group at 100 yards and by how much? I am sure that the 1 in 8 would be better from 600 -1000 yards. Where the heavy bullets come into play. Is the 1 in 8 as accurate at 100 yds as the 1 in 12. If not how much do I loose going to 1 in 8 to get a heavier that will useful at longer ranges? I am not really willing to give up a lot of accuracy to gain distance. With this being 6mmBR web site I thought I would have received a lot more reponds on what I thought was a real simple question.

You want the 1-12 bbl and shoot up to 75 or 80 gr bullets. The 6 br does not quite have the finesse at 100 yds that the 6PPC does, but at the longer ranges (300+) it does very well, if you have a 1-8 and shoot up to 107 gr bullets.

I am looking to buy another rifle to play with off the bench! I am leaning towards the Savage LRPV or Savage 6mmBR bench rest. The bench rest only comes in 1 in 8 twist. Which was one of the reasons for this post. The LRPV comes in both 1 in 8 and 1 in 12.

 

[squirrelduster]

I have a 1:8 and shoot 75 gr VMAX for squirrels. It shoots under a dime size group at 200 yards and is absolutely deadly out to 500 yards. I had planned on shooting the bigger bullets but had good accuracy with the 75gr VMAX with a little more speed.
You won't have a ground hog crawl away from these things. I believe the high RPM of the bullet helps in the killing. Instant death. Some of the other bullets i tried didn't really perform as they should. I had a couple of our large California ground squirrels crawl away from the bigger bullets. Not the VMAX, they are usually somewhat beside themselves.

I have had the Savage benchrest gun in 6BR with the 8 twist. If you intend on using to hunt with it at all you better have a good quality bench to be shooting off of when hunting because it is rather heavy. I took my 30" 6BR 8 twist off the benchrest gun and put it on my LRPV so I would not be limited to using a front rest when shooting it. I can shoot the LRPV off a bipod and it is a little more portable but still heavy. I had the 12 twist on the LPRV and opted for the 8 twist becuase it will still shoot the 70gr sierra blitzkings sub 1/2 moa at 100yds for the varmints but still have the option of shooting the 105gr A-Max for deer hunting. Hope this helps.

k80skeet,

It look like you question have not been answered. I like to twist my barrels for what I shoot. The 8tw is a good all around barrel, it will shoot all the bullets. It all depends on the barrel, most 8tw will shoot them very well, but not as good.

The 12 tw shooting 68 to 80gr Benchrest bullet will out shoot most 8tw, shooting the same. You will not limit your self with a 12tw, you are getting the barrel for what you are wanting to shoot.

The light Benchrest bullets are the best bullet made, bar none. I shoot 12 tw with 68gr custom made bullets for all my shooting out to 500yds. Get to 12tw, if you want to get into longrange, add a 8tw later. I shoot 70 Sierria Blitzkings for varmint with great results, with kills on VA Grondhogs past 600 yds.
