I`m just curious about this because the Nitro loads use alot of #7 Hevi-shot and I`ve talked with alot of guys that have absolutely slammed birds at 45 yards. A number of these guys say the birds don`t even flop when hit with these loads. I hope so because I`m trying them this year and just patterned my gun, I get 320 pellets in a 10" circle at 40 yards. That gives me around 45-55 spine and brain hits.
