I'm burning 115 grains of powder in my 378 per shot, and I wouldn't have it any other way

Also, my 'non-magnum' 45-70 burns 60+ grains of powder, in contrast to the 75-ish that the 458 burns. the increase in powder consumption isn't really that significant a factor

), I would seriously consider the 300 RUM (90 + grains behind 180/200's works very well). This cartridge is absolutely devastating with incredibly flat trajectory way out there...I am a believer!
