RE: Shot Size
The Triplex Nitro 4X5X7 is mostly 7 shot. Swamp Collie and the others are right - the 7 hevishot carries much more energy that lead and allows one to increase pattern density while still maintaining downrange energy.
I killed a turkey yesterday at 49 steps with the 4X5X7 3.5 inch, 2.25 oz. Nitro (Load #H51013M), Mossberg 835with a Star Dot .676 choke. The turkey never knew what hit him - multiple head and neck hits and when I got to him he was on his back with a broken neck and bleeding all over the place. The last time I patterned this load I got 246 hits in a 10" circle at 40 yards.
When I dressed the turkey I found that a single stray pellet had hit the turkey in the breast. It was a #7 pellet that entered the turkeys left side, passed through the left breast, the breast bone, the right breast, and came to rest against skin on the right side.
About a year ago someone on this forum (or maybe on the NWTF forum, I can't remember) posted a picture of the1/2 inchplywood board he wasusing to staplehis paper turkey targets on.He was targeting a load with straight 7s and those pellets completely penetrated the plywood ata laser-measured 40 yards.Very impressive.
I am completelty sold on hevishot, in particular the Nitroshells loaded by "Nitro Ray". This is my third season shooting hevishot (1 year with hevi-13 then the last two with Nitros) and I absolutely love their performance.
