Thanks.

I have a friend I gave an old 13.5 twist 6ppc barrel to who rechambered it to a 6 br. Scary accurate with 68 gr Fowlers.

Mine is a 13.5

I shoot 68 Avengers with N135 loaded with an 8” drop tube and Federal 205s. It’s been my favorite rifle for some time.

My 13.5 twist bull barrel for my heavy gun is chambered for 6BR and 66 to 70 gr bullets. For the last 16 years it has been easy to find loads for and has produced scary small groups at 100 and 200 yards.

Stekl shoots a slow twist 6BR.

L Murphy,
Yes, I have a fair amount of experience with slow twist 6MM barrels. Chambered and rechamberd enough to learn a few things.

Naturally the slow twist is intended for lighter bullets and as everyone is aware, for the last 50 years or so no one has consistently bested the slow twist 6MM’s with regards to short range accuracy.

So, if you looking to assemble possibly the best varmint or steel shooting rifle for 300yd’s or so, then the evidence clearly suggest a slow twist 6MM in PPC, 6BR or any of their cousins.

In my experience I prefer the 6BR in a zero freebore configuration. No problem sizzling 55 - 70 bullets at high volocitys while shooting consistently tiny groups.

Like everything else the slow twist have their place and the fast twist have theirs, shot lots of both and vastly prefer the slow twist for varmints.

A muzzle brake on a slow twist with light bullets results in a varmint rifle that hardly moves when shot.....get to watch a lot more varmint gymnastics with a brake.

Not sure what answer your looking for..........hope this helps.

13.5 Twist is pretty common in the 6PPC so I would THINK that in 6BR it would work great with the appropriate projectiles.

I am having a new 6mmbr being built on a Bat SV action and a 13 1/2 this the twist I picked for my heavy Krieger Barrel.

What grain bullet and powder are you wanting to try?

 

[AckleymanII]

55g bullets- AA2230, Rem 7 1/2, Accuracy node at 3900 fps in my 27" Lilja-12T-zero freebore

55g, 60g-70g bullets- H335, Rem 7 1/2, really amazing accuracy

expect sub 1/4" groups with all these bullet weights. Accuracy node is at the top of the pressure curve

 

[rkittine]

I have had good luck with Berger Columns. Last lot I bought were 64.2 Grains.

 

[k80skeet]

What grain bullet and powder are you wanting to try?

I am thinking Varget, 8208, Lt32, AA2230 and a few others. 62-70gr bullets.

 

[Murray Brook]

AR-Comp is also a great powder with 62-70 gr bullets in the 6 br. Works great in mine with the 64 gr Berger column.

 

[Mark W]

I can’t make guarantees in a straight 6 BR, but H335 and H322 both work really good fire forming 6 BR to 6 BRA with 55-70 grain bullets.

Purchased a 6mmBR w/ 1-14 Tw. from a member here on the forum. It was very accurate with the 65 & 68 gr. Bergers.

I hope it shoots 66gr Fowlers (as I have 2000 of them) and some 65 Genter's as I have some of those too.

Didn't try either of those but it probably would have shot those as well. I had Zack @ ODCR re-barrel it to 260AI.

You just never know and that's the fun part is finding out.

You are indeed one lucky rascal!

LOL. I definitely love my 260AI both in 40X and 700 form.
