So here are some tables and charts relating to my pattern testing with coyote ammo in this Benelli M2 the last couple months. Note – I finished these tables and charts before doing the 70 yard pattern, so it's not included in any of them. And that 70 yarder was way better than could have been predicted by previous results at 60 yards. Again, tiny sample size, makes for lumpy data, but it's all I have at this point.
Here are the results of considerable pattern testing at 40, 50 and 60 yards in table format – note, most of these loads were tested with multiple shots each with at least a few chokes and these results represent the best of each not the average.

And here is some of the same data in chart format, showing the number of pellets that hit in the 10” circle at different distances for the same group of loads.

And another chart showing how many pellets hit the 2'x2' backer paper for the same group of tests. An indication of overall pattern size and density, which shouldn't be ignored – I'm not interested in turning my shotgun into a rifle here, being able to make hits on close in, fast running coyotes flying through the sage brush is my primary use and interest for the shotgun.

Bottom line on pattern testing, TSS patterns better than anything I have ever tried.
Before moving on to penetration testing, a few of the data points that stand out to me:
- Excluding TSS, the previous three way tie for most pellets in 10" at 50 yards was only 13. The 37 in the 10" at 50 yards for TSS #2 is almost three times as many hits as previously seen with this gun.
- My Hevi-shot BB load, with 72 pellets total and 25 pellets in the 10" at 40 yards, has proven a good coyote killer for me out to about 45 yards. TSS #2, with 94 pellets total, puts the same 25 pellets in the 10", at 60 yards, with much better penetration!
- TSS #4, with 123 hits on the 2'x2' paper at 40 yards and 32 hits in the 10" at 50 yards, with overall better penetration than Hevi-shot BB, is going to be just a big, dense, nasty swarm of death out to 50 yards.
- Dead Coyote T is a well proven effective coyote load. But TSS #2 just beats the heck out of DC in every test. Patterns and penetration with TSS #2 are just far superior to Dead Coyote T. It's not even close!
Next up, penetration...
