RE: Patterning Question
I used Nitro HeviShot 4x5x7 on one bird this spring, at 25 yards, and he fell instantly, "no flop."
I used straight #5 Remington HeviShot on two others, with less instant killing effect, but they both succumbed and are in my bag. Nitro is WAY too expensive, IMHO, (on a scale that factors in price, pattern and results) though, so I think I'm going back to my old reliable, #5 Federal lead, until something better comes along.
I haven't seen a commercially made 4x5x7 or comparable, in lead, but would probably use it if I did find some. I think a blended shell puts more killing pellets in the vitals area, even though some of the pellets have less energy when they reach the target.
I do not like Remington's HeviShot, because the crimps are crappy (IMHO) and the buffer leaks.
