180 gr Partition w/cannelure

[brokenspoke]

Has anyone experimented with the partitions with & without the cannelure? I just got some 180's with a cannelure & was wondering how much different if any they will shoot than the ones without. If anyone has any experience with them I'd like to hear it.

Not with 180 gr Partitions but with 160 gr Partitions out of a 280 Rem. Shooting out to 300 yds I didn't notice any measurable difference in group size between those with and those without cannelures. YMMV.
