Varget has been my go to powder for many cartridges but the 308 in barrel lengths from 20-26" has been nothing short of magic for me for many many years.
Another couple of advantages of using a medium to fast burning powder are.....
1. A more pleasant perceived recoil impulse.
2. Less muzzle blast.
Part of the advantage of the short magnums has always been their enhanced performance with the medium to fast burning powders and that's a large part of why a 300SAUM has a MUCH more shoulder friendly recoil compared to a 300 Win Mag for a small loss in velocity until you get to the bullets on the heavier end of the scale.
This is just one of my favorite differences to point out but the difference in recoil a 7mm Remington Magnum and a 7mmSAUM have is huge too and the SAUM performs better in shorter, therefore lighter, barrels than the 7RM.
With the advent of the super high BC bullets in the last few years the popularity of the super magnums is waning rapidly as the high muzzle velocity advantage disappears rapidly as distance increases and it becomes all about BC.
Many old school shooters are probably sitting up in their chairs and angrily reaching for their keyboards to justify their fire breathing dragons but they and their rifles with the giant cartridge cases are quickly becoming dinosaurs.
These are the good ole days of centerfire rifles and even off the shelf factory rifles with diminutive cartridges are now capable of respectable groups and terminal performance at distances reserved to a few fire breathing dragon rifles of relatively recent past.
Yes boys and girls. The 308 and now the 6.5 Creedmoor (and several notable others) have all but replaced the Magnums and Ultra Magnums of recent past and my shoulder is happy about that. Back in the day I shot enough 300 Win Mag and 30-378 Weatherby Magnums to permanently rattle my already feeble old brain.
