So I have my barrel set up and some 458 300 gr tipped barnes bullets coming.

These open fast and are designed for the 458 socom lower speeds.
t any rate I want to load them toat about 2000-2200 for a reduced load.

I contacted Barnes and they said to load them over H4895.

H4895 will fill the case, but only 80% burn so a huge fireball.

Still waiting to hear back from Hodgdon.

Anybody shooting 300 gr reduced loads out of a 458 winmag ??
