Can anyone really tell the differance between a #7.5 and a #8 load?? I shoot trap and am not good enough to really get a feel between the two.
Which do you use ?

In the search bar I’d look up “7 1/2 vs 8s for trap” and scroll through and read the past threads. Heavily discussed topic with the answer being whatever you have working best. Unless your at the 24+ yard line a shell that’s legal is a shell that’s legal.

Thank you all, I’ve been wanting to have this discussion for so long but thought it was a silly question.
It's not that it is a silly question, because it's not.

It's just that on this forum, it's been brought up countless times, and the answer remains the same.

For singles and doubles, it doesn't matter.

For long yardage handicap, it might matter, but there's a lot of evidence that it doesn't matter there either.

Keep in mind, when you buy a box of cartridges, it's a crap shoot as to what size pellets you're actually going to get, regardless of what it says on the box.

If you look at this table linked below, most of these cartridges are Number 7-1/2, but if you look at the actual pellet counts, one or two of them are almost Number 7, and several of them are close to being Number 8 (Fiocchi). Most are somewhere in between.

I’m confident that one 7 1/2 will break the target in all conditions from 16yds but Iam not confident that one 7 1/2 pellet will break a long yardage target as I believe it takes atleast two and maybe three pellets to fracture the target sufficiently to spin apart.

So I use 7 1/2’s for 16’s and use 8’s for handicap to gain more pellets on the target.

Interesting...your logic is the opposite of everyone I have seen/heard, who all advocate 8's for singles, 7.5 for handicap. This leads me to two possible conclusions
1. You are messing with the OP (a very likely scenario)
2. You should use 9's for handicap to further increase your odds of multiple hits

Unfortunately, using smaller shot doesn't lead to enough of a higher probability of "one more" pellet strike to justify the loss of energy/velocity compared to larger shot. You only get 17% more 8's (compared to 7.5's) so at most that one pellet strike with 7.5s becomes 1.17 pellet strikes with 8's. Since pellets only come in eaches, you don't get "one more" pellet strike unless you already are getting many, many strikes with 7.5's. And at that point it doesn't matter.
