[QUOTE="load, post: 622443, member: 22789"] heavy short barrels are the best for all around consistency. this is why the military has gone to 22" barrels on their 300 win mags. their load is still getting 2850 with a 220 grain smk (albeit max/high pressures) and the 22" bull barrel combo. The reason is simple; fat barrels take longer to heat up, consistant barrel contour (i.e. bull or straight) have consistant heat expansion and shorter/fatter barrels create less harmonics than longer/slimmer barrels. when shooting scoped rifles a longer barrel does not make a more accurate weapon just the opposite.gun) [/QUOTE]
