6.5 grendel

[bignoalse]

I am wanting to build a 6.5 Grendel bolt gun. I purchased a Pac-Nor 6.5 barrel blank that has a 1:12 twist from a guy. Is this to much twist or what grain bullet would this be good for? please let me know your opinions it would be greatly appreciated.

I think all you can stabilize with that slow twist will be the 85-90 grain

I have Nesika Pistol with a Krieger 1 in 8 twist. Shoots real good.

I second tonedaddy's advice on using an 8 twist barrel for the grendel.

the slowest I have is a 9 twist. The rest are 8 twists. I would not go any slower than a 9. Matt

Well I realize the 1:8and 1:9 twist would be better. But I already have the 1:12 twist blank is the reason I asked what size bullet would work

 

[BOBC]

83 to 94 gr bullet. I made some 107gr BT's with an 8cal point that shot well in a Grendel with a 9 twist, but a 12 is too slow for
any heavy bullets in a Grendel.

I know where your coming from trying to work with what you have.
But the 85-90 grain 6.5mm bullets can be pretty hard to find
something to consider

Is this to much twist or what grain bullet would this be good for?.

Too much? Not hardly, if you expect to shoot anything heavier than maybe an 85-90 grain bullet as others have said. Given the unmodified case capacity it's a cartridge best suited to bullets under 131 grains anyway & those'd need a 1:8. Limit yourself to 107's & you could go with a 1:9 but why bother when the 119 - 123's shoot so good in a 1:8 & the 107's will too.

If it's an unchambered & unfitted barrel now you may be better off finding it a new home rather than spend good money having it cut to fit then find yourself limited to the lighter weight .260" bullets. There are some good ones - make no mistake - so it depends on what you intend to do with it in the end I guess.

Well no cost machining and chambering. Im a machinist and have personal equipment, this would not be my first barrel. I greatly appreciate all the info. Thanks

Even with "free labor" involved, you might want to opt for a different barrel (faster twist) and sell this one or use for another project. Just not a good assortment of light enough bullets out there in this caliber.

well ended up getting another barrel with 1:8 twist

;D. Great move, a lot of guys post questions but they really have their mind made up. Good to see someone open to listening to the input they get
