Will be trying Winchester STABALL with some 528-gr Lehighs for supersonic in "Tootsie"
the .458 B&M+ of 1:10" twist with 17" barrel length (16.9" actual).
She has same case capacity and throat as the .458 WinMag.
Same loads can then be tried in Freki the .458 WM (24.25" barrel length, 1:10" twist).
Both barrels are Pac-Nor, #5 Sporter on Freki, #4 sporter on Tootsie.
Both have Near Mfg rails and interchangeable scopes.
This will give another check on how shortening from 24" to 17" affects MV,
this time with a heavier bullet and slower powder, ought to be a wash,
about the same as with a lighter bullet and a faster powder,
and this time with same twist.
The difference between 1:10" and 1:14" is near insignificant, of course.
1:10" might be of use with the subsonic-suppressed plinking with the long bullets.
Here is 1:10" twist Tootsie:

Tootsie makes a better sleeping-tent/latrine rifle with a little red-dot on her rail,
or maybe a little flashlight and laser needs to be hung at the forend tip, like on Ol'Fugly.
