Is an 8 twist too slow for 140 grain bullets?

[EasternNChunter]

I am planning on building a 6.5x47 for shooting out to 1200+ yards. I ordered a Bartlien 8 twist 27" M24 barrel from Bugholes. It should be here tomorrow. My buddies are saying that I should have ordered a 8.5 twist if I want to shoot 140 VLDs and AMAXs. Did I mess up and should I send the barrel back (if they will take it) and get an 8.5 twist or sell it and buy another barrel?

An 8 twist is faster than an 8.5, so it definitely isn't too slow. I like 8.5's better, but a lot of guys shoot 8 twists with great success.

You did good.

 

[TRAAV]

Your fine with that

Your 8 twist Bartlien from Bugholes will shoot bugholes with the 140's! Don't stress out over 8 vs 8.5 vs even 9 twist and the 140's...

no worries, 1-8 is plenty of twist for just about all the 6.5 from 120 to 142's.

got an 8 twist on my creed and it shoots the 140's great

Its probably going to cause air bursts, terrible accuracy, and be down right dangerous. Just kidding, but I think 8 twist is the gold standard for the 6.5mm heavies. I've taken amaxs/bergers to nearly 3000fps and have had no issues. I've also ran them very slow and it did really great.

I shot nothing but 1:8 on my 6.5-284, 139gr scenars at 3100-3150fps and no issues at all.

Couldn't agree more with this.

I have 6.5x47's in both 1:8.5 and 1:8 twists and they both shoot 123's and 130's equally as well as the other. I just received and will be playing with the 136 Scenars possibly tomorrow since it will be a high of 70 and sunny, couldn't ask for a better day off!

I'll keep you posted.

Thanks fellas! Keep me posted Bob.

I got an 1:8 twist and it works great.
