Looking to buy new/blank 7.5 twist 6mm.

Straight no contour

If you could live with an 8 twist, Krieger has a 1.25" straight on their inventory list.

Will that stabilize 109 Bergers ?

Not really. Go here to find out what will be stable. You really want a 7.5T.

Yes. My current Dasher is Krieger is a 1:8 26" and hammers with 109s. That same barrel referenced above 1.250 straight.

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

Look pretty stable to me

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.

You can get a PVA 7 twist and it will handle whatever you want in a 6mm. I shoot 105, 108 and 110s through my two.

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.
