Twist rate…

Based on my 500bpe experiments, I don't think it will.

Typical factory 45-70 twist is 1:20 or 1:22 with the heavy bullet long range rifles being an exception. Looked up the CVA Scout mentioned and it is 1:20.

My 500bpe has a 1:26 twist and I have recently pushed 15bhn 328gr PP bullets to 2025fps average seeking regulation with black powder.

Not a lot of standards back in the BPE days, and yet the Adams & Tait (sometimes spelled Tate) barrel makers could probably be considered to be making a 'standard' twist since a lot of firearms makers used their rifled tubes. My Braddell used them, and you can see their "A & T" stamp and their barrel serial numbers which were also likely used to keep track of money owed Henry for use of his rifling. Now wish I had measured the 450bpe twist while it was here.

Granted, not an exact comparison, but it does illustrate my thought process.
