I'll see if I can't dig up a pattern to show you from the guys that have used it.

Here's one timb from Old Gobbler shot at a lasered 40yds with his 1187 SM and the Fed Hvyweight 3.5" #7's and a Trulock choke.

Another guy there that goes by wvnut3 also says he avg 210 to 215 with the same gun and a Trulock choke. I think George Trulock made a choke specially designed to shoot these Fed Hvyweight loads.

Those are impressive patterns as expected with small pellets and if the energy is sufficient to make them effective at longer ranges aka adding value over a larger pellet I'm all ears!..........hey Brad that video you posted was Todd using 7s wasn't it?

I was going to start a new thread but will just include it here how much does ftps come in to play for example hevi 13 is rated at 1090 where as the mag blend is over 1200 where as nitro ammo loads are 12-1300 is a 7 at 1250 ftps equivalent to a 6 at 1090 ect.

Todd can shoot better than that.

Well I will tell you this much that I have learned from reloading shells myself that not to get caught up in the fps game. 1200fps vs 1100fps don't mean much once the pattern gets out there at say 40yds. I read a long time ago in magazine from a guy that seem to know his stuff that the difference from a load shot at 1200fps vs say 1100fps don't mean didly by the time they hit the 40yd mark. Both are going to slow down tremendously at that distance vs what you started with at the muzzle. I would worry more about how dense my pattern was before I worried about a load that shot 100 to 150fps faster.

I'll tell you also that the slower load will typically pattern better than the faster load.

The slower heavier turkey loads will be less erratic and more consistent more times than not vs the faster turkey loads.

That was my thinking with a basic understanding of KE retention without in depth research. Same as in archery heavier has way more to do with penetration than size and to some extent speed.
