Re: 338 Imperial loads???
Can't find any info on the Imperial but if it's a 404 necked down your about right
with 91grs of H 1000. but if it has been blown out and the sholder moved forward
then you can probably go up to about 94 to 96grs but go slow .
If you know someone with a 338 RUM try to compair the two.
The rum will hold 101grs of H 1000 dumped and 103 to 104grs with drop tube .
Your at a good starting point, watch for pressure and work up slowly.
