[QUOTE="ObiWanKannoli, post: 2771953, member: 116692"] What people miss a lot in the Contour and Can conversation is barrel harmonics. Hanging a big heavy object of the tip of an Ultralight sporter barrel will likely have a negative impact on your accuracy and certainly induce a poa/poi shift. The lighter the profile, the more dramatic the effect. Shorter barrels by physics will have less whip and flex to them, this can for sure cover some of the ill effects of a super light contour barrel with a can. Weight of the can, length of the can, contour of the barrel and length of the barrel are all variables here. Best harmonics will be from short, fat barrels with with a short, light can. Worst harmonics will be from a long, light Contour barrel with a long, heavy can. If you reload, expect to have to rework your load as well depending on how high backpressure of a can you are using.
