7mm 1 in 14?

[MClark]

Organizing barrel blanks at work I came up with an odd stray, a 7mm with 1 in 14 twist. I think it may have came from Apex, cut rifled.. We do not have the rifling button to make one.
Using the twist calculator on the Berger Bullets website it looks like it will be able to stabilize some 120 grain bullets, not VLD or tipped. Does this sound correct?
Anybody used a slow twist 7 ? I have a vision of a 7 BR rifle.

The SAUM pushes a 120 gr. V-Max to 3650 fps from a 28" 9tw. ;D

my two 7br stabilized the 130 from 10 twist very well, 140's ok but not quite as well - 130s would go under moa at 200 meter 140 just at moa and 150's at best 1.5 moa--- hart bbls 15"

they problem you will have is the velocity from the br case will not help

I could see it working out with the light TNT bullets. Kinda like a 30BR for short range BR.

That is where I was going, but not a BR but a walking varminter and if proper bullets will stabilize deer.
The selection of light 7mm is not great, but all I need is one that will group.

Mark,

the 7br xp100's I described pushed the 130 Sierra 130 ssp at 2450 from a 15 " bbl, they are thin jacket and deadly on deer, all I shot were drt. that I believe would be the better choice for varmint and deer. very accurate
