Until somebody shows me some concrete evidence that the hevi 13 shot will penatrate better at 40-45 yards than Win HV #5's... I've got a hard time buying the 60 yard kills... That stuff only going around 1090fps...
I have patterned it with the Primos jelly head choke and it definetly patterned better!!! But I missed a gobbler last spring at 50 paces with it... I definetly hit the bird but he flew off

I looked for about 1/2 hour just in case he flew off and died... Nothing...
I will be doing some penatration test with the Hevi 13 and the Win HV #5's in the next month or so... I will be shooting them both at a phone book at 45 yards and counting the amount of pages that they pass threw... ThenI'll shoot them both at a peice thin sheet metal(1/32") and compare the dents... After I do this test then I'll know what the real deal is!!! I will post my test results...
