OK, Federal HW 7's.

[Tail Feathers]

I only see the 7's on-line in 1 1/8 oz.  Are these the loads or should I look for a 3" version?

Those are the 2 3/4" shell you see. The 3" 1 1 /2 oz.#7 HW is the shell. Try Dunns,Sportsman's Guide,CTD, mack's prarie Wings, Cabela's, Sportsman's Warehouse, and others as there are some out there.

Thanks.  I found some 1/5oz 7's on-line after a search.  Ordered two boxes.
I hope I can get a solid 35 yard gun out of it for the boys.

35 won't be a problem.

You could squeeze that out of the 2.75" loads.
