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 ?

Pellet count of 164 in a 9/8 oz load?
You must be referring to size 4 shot. Or, your numbers are bogus.

Well, I have bags of Heper 7.5 from 2023 and 2024. And they yield actual pellet counts of 406 and 409 for 9/8oz drops.

And, how are you determining the size differentiation?

My bad, the Cheddite shell results are based off a 1/2 ounce sample of shot removed from the shells. These were nominally 1 ounce loads but it was easier to check a sample to get a true weight. I suspect the Cheddite shells use the softest of pellets with little to no antimony.
The Heper shot is a 1 ounce sample. The 372 pellets per ounce would net to about 418 for 1 1/8 ounce. I had several other bags of Heper that looked better, but I didn't check them. This bag looks visibly small even with just a glance.
I am measuring the diameter optically - I may offer this as a tool in the future if I feel it is repeatable and user-friendly.

I have posted on this topic in the past, some thoughtful, some humorous. But for me the reason is pragmatic. Besides ATA, I belong to and shoot at a number of clubs. Some of these have down range curtains to prevent shot from going into wetlands, or off of their property.

And in one case the club has limited shot size to eight or smaller pellet size. This is because the combination of distance, height of curtain, strength of curtain material and prevailing winds requires lighter shot. Some 7.5 loads will punch holes in the curtains, and they are expensive to buy and even more expensive to install.

So given the need to buy various speeds for various uses, and using several thousand rounds a year, i just buy eights to keep the inventory permutations down.

Yes, it has been brought up many times but there are always people new to Trap so let’s not disparage but provide guidance. For me, because there are more (and smaller size) pellets - #8 than with 7.5 I tend to use 8’s on a quiet wind day and 7.5’s when the wind is picking up. I use either 1oz or 1 1/8. Hope yhat helps.
