Question:
On page 307. Under heading, 150 grain BULLET:
H4895 (powder) 34.0 (grain) V=2409 40900 CUP
On page 308. Under heading, 150 grain JACKETED: H4895, 35.5 grs, V=2315, 38000 CUP
Can anyone explain the difference between BULLET and JACKETED that would give a 34.0 grain charge greater velocity, and pressure, then a 35.5 grain one?
E-mail responses are welcome.
