Re: question on barrel twist

If you were absolutely looking to squeeze every last fps out of the cartridge I would suggest going with a slower twist.

With the 1-9 your not going to notice anything different about the way it handles your loads, with the standard 140's. However if you decided to shoot some Berger 140's that would give the faster twist a better handle on the longer bullet.

Also who knows what the future might hold.

I got a 7mm Rem Mag and was going to only shoot the 130 - 150 rg bullets and still haven't worked up a load for them yet. I got a deal on some 162gr bullets and they have been shot in it since I have had it. I also have a STW and other than playing with a few of the heavy bullets, I am shooting factory Federal 150gr Nosler Solid base loads in it. Go figure.

Good luck with which ever you go with, one last thing, depending on who you end up going with, some might already have one with a 9 twist sitting there ready to go where they might have to make the slower one. Just something to consider and ask about when you order. With the time it sometimes takes to get one made and delivered, I know that would definitely make a deal for me.

Re: question on barrel twist

I shoot 105 VLD- they recommend 8" twist but it does very well out of my 243 win steven rifle that is 9 1/4" twist. But this loaded maxed out with the most velocity/lowest pressure kind of powder I could find(3050fps). Always thought that the higher velocity is what stabilized the bullet.

Re: question on barrel twist

The reason I recomended 1 in 9 is because it has always worked no matter what bullet
I shot in the 7/08s I have seen or built.

I shoot 120grain bullets in my 7/08 and the best 5 shot group to date has been .053 @ 100
yards. It will also shoot the 140gr and the 160 gr Accubonds under 1/10th of an inch (.100).

The slower or faster twist may work well for specific bullets but the 1 in 9 is the best all
round twist rate in my opinion.
