150rds today at 210m, but I think that's already past the limit of the ammo consistency with the Eley standard. I had two rounds go supersonic (one almost sounded like a WMR), and perhaps as many as ten went very subsonic out of the 500rd box. One of the "fffftttt" rounds actually hit the Turkey, so was about 500mm low at 210m. The fffftttt's also don't seal the chamber so gas comes back around the bolt. It's Eley's cheapest ammo so not unreasonable, but I'll have to switch to something else to push the distance.
I was using 26.75-minutes at 185m (50m zero) and calculated 32-minutes at 210m, but it actually only needed 30.5 in today's conditions. Today was a fairly steady 5-7mph from right to left mostly but with regular fits of 10mph from the right to 5mph from the left.
A plow disc was too easy, even for the first shot of the day (it was my "sighter"), so I stopped at one mag.

The 220x420mm plate was a little more challenging with the wind, but overall quite easy to hit. I fired 40rds and got about 20 hits. You can see I was dialing down the excess holdover during these rounds, as they were shooting high. The "group" would've been around 300mm I'd say, probabaly a little less

I tried a mag on the 6" gong with a perfect score of ten clean misses
I forgot to get a photo of that!
I even tried a couple mags of a "ding" on the plate, same hold on the gong for a miss, back to the plate for a "ding", back to the gong for a miss, and so on, keeping my perfect score on the gong. For comparison, the gong is .018m2, compared to the plate at .092m2, and the plow disc at about .100m2. The gong is less than a fifth of the area of the plow disc.
The wind was being pretty stroppy. I tried one magazine of waiting for the flag to drop for each shot - highly recommended if you're looking for a way to suck all enjoyment out of your shooting
So I went up and painted the targets. I put a few more mags onto the plate, then, feeling cocky I tried 10rds on the 6" gong, and managed two hits, the centre one appearing right on the crosshair.

Then I put one mag on the ram with six hits

.
Then for the last mag I thought I'd try the 5" gong, and amazingly my 150th round of the day was a hit, a great finish

Regarding underpowered ammo spitting gas back around the case, S&B Shorts are very, very nasty for this in the BSA Sportsman 5 - wear glasses if you try it.
