[QUOTE="Greg Duerr, post: 831367, member: 32685"] I hear a lot about barrel length and velocity. For every inch increase in barrel lenght their is approx 35 fps increase in velocity, is this true or does it vary from barrel to barrel or from cartridge to cartridge? I saw a report a few years ago in Guns and Ammo that took a Rem 6mm and a Rem 280 both with 24 in barrels and ran a velocity check at the 24inch lenght then cut off one inch recrowned and recheck the velocity.........it was surprising that the hightest velocity was with the shorter barrel lengths.................for me it was food for thought that often we are set in one way of thinking when in reality that might be wrong. Its a lot like the thoughts about premium bullets over standard. I alway compared bullets to the Nosler Partition. When at the Elk Foundation in Reno, Nevada I talked with some hunters from South Africa and asked what bullets they prefer hunting to come with all of them did not recomend the Partitions as they have seen to many failures with frontal core seperation. We all have our experiances but coming from hunters who guide and who see hundreds of kills that caught me off guard. I get set in my way of thinking and then all of a sudden somthing comes along and redirects it. Greg [/QUOTE]
