Was doing a search on this topic and found this old thread. I'm wanting to load up some light practice rounds in .308. Lee Modern Reloading has a seperate section with tables for reduced loads for 30-30, 30-06, and .308--these loads are specifically designated cast lead bullet loads. Any reason the same powder charges couldn't be used for jacketed bullets of equal weight? Powders include Blc2 and Varget.

Yes.

Jacketed bullets take MUCH greater force to push through the bore due to the harder jacket material.

Using reduced loads it's possible to get a bullet stuck in the bore.

Lee Modern Reloading offers, for example:

110 Grain (cast lead) bullet
BLC2
from
25grains at 1950fps and 16700 PSI
to
46grains at 2910 and 45900 PSI

150 Grain (cast lead) bullet
BLC2
from
25grains at 1820fps and 11200 PSI
to
44grains at 2630fps and 44600 PSI


Jacketed bullet loads, in the main load section at the back:

110 grain Barnes X bullet (there is not BLC2 listing for regular jacketd bullet)
BLC2
from
48 grains 3028fps, no pressure given
to
52 grains at 3268fps and 61285 PSI

150 grain jacketed bullet
BLC2
from
45 at 2681fps, no pressure given
48 grains BLC2 at 2839fps and 59615 PSI

Could a reduced jacketed bullet load be somewhere in the middle of those cast bullet ranges? Or does the higher weight starting load for jacketed bullets indicate that a lower load would be unsafe--liable to stick bullets?

(Or should I just shoot cast bullets for practice?)

Don't you have worry about combustion? Something about too little powder blowing up instead of burning?
I dunno, I'm just asking.
