A member directed this question of mine here from the technical forum.
All things being equal (barrel length, type of round) what effect might twist rate have on penetration thru barriers such as plywood/sheetrock (i.e. residental structures).
Example: Would a 55gr BTHP fired out of 16" barrell experience different levels of penetration at a 1:7 twist rate vs a 1:9 twist? (assume the twist is not effecting velocity).
