6mm Ackley Improved question

Hey everyone, I am getting ready to build a 6mm Remington Ackley Improved. I will be shooting 75grn V-MAX bullets, and I was woundering what twist you guys would recommend. I am currently thinking about a Kreiger 28" 1-14 twist 6 grove. I think this is the right choice, let me know what you guys think.

Re: 6mm Ackley Improved question

I would go with a 1 in 12 or even a 1 in 10 for 75s. Gives you the option to shoot heavier bullets if you want or need to. I have a 6mm-284 with a 1 in 13 and anything heavier than 80 grains doesnt shoot all that well.

I have an Argentine Mauser with 28" Shilen no.7 contour 10 twist chambered for 6MM Remington and this thing love the 87 grain V-Max stoked with 43 grains of IMR 4350 at around 3300 fps. I lost count of how many ground squirrels and crows bit the dust by this rifle and round combination.

Re: 6mm Ackley Improved question

With a 1-10 twist but different cartridge, I was doing better than 0.5 MOA at 500yds with the 75 SMK. 75 gr bullets have a low BC and you need calm days to get very far out with them, unless of course you just enjoy the shooting which can be a lot of fun when the winds are tricky. Currently being rebarreled to a 1-8 twist for 105-107 gr bullets.

Might want to view this as a lesson and not repeat other's mistakes.

With a cartridge like the 6mm AI, why would you want to limit yourself to light bullets???

My .243 Savage had 9.25" twist and it shot the 55 gr BT into one ragged hole @ 100 yds. On the flip side, it also shot the 105 Amax very well!!!

Go with an 8" or 9" twist so you can shoot both.

Re: 6mm Ackley Improved question

Go with a 1-9" twist. Why would you want to limit yourself to the 75 grain bullets? I just cannot convince myself to load anything other than the vld's or the really light 55-60 gr bullets. The 55's will do well out to 400yds but then you really need the VLD's to fight the wind. What am I missing here with the middle weight bullets? I have a 1-9 243AI and by the way the Lapua brass is the best no neck turn brass for any 6mm out there. So unless you already have dies for the 6mm then you should really consider the 243 AI especially if its a short action. I'd think the 55 ers at 4000+ out of a fast twist barrel would make a bigger splat than anything the mid weights have to offer.
