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.

I haven't seen the book, but maybe they meant to say cast bullet? They have an 800 number. Call and ask. They've probably had it brought to their attention many times already, and will have an answer ready. Reddog

Reddog,

They do have a section for cast lead 150gr bullets. Thanks for their phone number.

John,
There is a segment in that book just before the loading data where the author explains the hows and whys of the way he broke down his sections into bullets, lead bullets, and jacketed. Right off hand I can't recall what he says there, but I will reread that tonight -- you just piqued my curiousity!

Jack,

You are correct. Pages 173 through 177 are entiled "HOW TO READ THE LOAD DATA". However, I can't find these pages listed in the "FORWORD" (table of contents) which strikes me as sort of strange. Anyway, it states, "Grain Bullet, this is common with Hodgdon powders. It means you can use any reasonable bullet..."

Thanks for the tip.
