For bush and hunting, this would be a neat idea, however I'm skeptical about how many clubs, especially near major centers, would actually let you use it, simply due to ever tightening ammo restrictions. 7.5 is the max at (I dare say) all skeet/trap/sporting ranges, so if you show up with home made shot, it could pose serious liability issues (eg Dewinton MUST say target on the box, nothing that even says field). FITASC actually outlaws totally the use of reloads.
My 2 cents aside, it's neat that the option is out there.
It's the liability issue more than anything. You may have the best screen out there, but without destructive testing there is no way to prove it to the range (or the lawyers); with commercial ammo, even if there is a screw up, you, and the club, can look at the box and go "see, it' says 7.5".
I suspect that 99% of ranges in canada and 100% of the dozen or so I have visited have never checked ammo. Tons of people reload, even with commercially available shot, you could use any size, fortunately most people are honest.

Where does the liability come into play?? If one uses No.8 vs 7 1/2 never witness this before so curious

They don't care if you are using #8 instead of 7 1/2. The problem comes into play when you start using bigger shot (e.g. #5 or #6 or bigger) instead of 7 1/2.
