Been shooting 3.5" Winchester HV #6's since they came out. I may switch to Hevi at some point, but I haven't had any issues killing turkeys with that load, so I've not switched over. There is no denying that the Hevi patterns are quite impressive, but I always figured......."sort of dead" was a lot like "sort of pregnant", and the HV's have been doing a good job of making turkeys "sort of dead" for me.
