Accessories WTB 6mm 7.5 twist blank

If you could live with an 8 twist, Krieger has a 1.25" straight on their inventory list.
 
Not really. Go here to find out what will be stable. You really want a 7.5T.

 
From the Berger website for the 109 gr Long Range Hybrid Target:

" It offers the same stability factor as the industry-leading 105gr Hybrid Target and is a direct replacement for 1:8″ twist barrels"

 
Strange that their own calculator says it's marginally stable.

Taking it as high as 3200fps which is completely unreasonable still only gets you 1.45. 2950 fps is still 1.41 but most people aren't even going to run them that high.
 
This is for a 6bra, Iam guessing 2850fps is what would see….
I run them at 2860.
I don't think you will have a issue with 8 twist personally. But Ive seen a guy selling 7.5 twist straights on here recently. I think they are MODBB though if that matters.

 

This is an awesome deal, great barrel. Shoot him a pm about thoughts on stabilizing. He would know I’m sure as he’s one of the best.
