Yes. Above.
Crimping almost always improves sd and es. It gives more consistant start to the bullets (both Hunters and Absolutes). Start with a light crimp (1/8 turn). Go up til you find pressure with your powder charge. Back off 1 grain and shoot groups.
Adjust powder and get best load. Do final tuning by adjusting final crimp in 1/8th turns. Your groups will open and close (just like changing powder does). When done, you'll have your best, most accurate load.
Holding bullets snugly in a magazine is an ancillary benefit.
