Guys,

I'm loading 38special. Bullet is a Rainier Ballistics 158grain FP (copper jacketed). In using both the Hornady and Lyman guides I find the following info

1) Lyman-for a 158 grain jacketed HP, OAL length recommended is 1.480

2) Hornady-for a 158 jacketed FP (Hornady XTP bullet, not Rainier) recommended COL (which I assume is the same as OAL) is 1.450.

Since neither manual has the bullet I'm loading, how should the OAL be determined? And, how critical is the measurement itself-ie. can there be a range of acceptable OAL provided it doesn't exceed the maximum length listed.

Thanks for the help on this one.

Gerry
