Looking for performance testing data and discussion on how the ol' FBI Load performs in small S&W J-frames with the 158-gr. LSWCHP's.
Given: Most 158-gr. LSWCHP's are +P and generally achieve 890 fps in a 4" barrel.
Question:
Can a 2" snubby achieve 800 fps and how much penetration or expansion will the FBI Load generally yield? (14" and .60" would be great.)
In comparison, Speer's 135-gr. +P SB Gold Dot (865 fps in a 2" snubby) generally results in 11" penetration and .57" expansion.
Thank-you in advance of your technical assistance!
