Thanks for the picture, appreciate it! Is the “new” version on top?I'll include a picture of skirts. It is a hard thing to get a picture of, however. The picture is dark, I do not know why, it was taken under strong light. Transferring it to my laptop was a huge pain for some reason. I cannot work exclusively from my phone like some of you probably do.
Perhaps more importantly I think I solved this for myself and possibly others. I shot a poor target yesterday with the old 18.3 grain AEAs. To try and understand why I shot some groups where I played with the velocity. I will save you looking at all the results but I have one target I think is more important that I will share. I was repeatedly able to get my 3 shot groups at 30 yards down under 1/4 inch with the old design AEA by increasing their velocity to about 895. You see one of these in the upper right corner of the second attachment. I have several more. The target has the velocity of each of the three shots. The old AEA are the top row of the target, below that is H&N Baracuda 18 grain and the third row and the far right target on the 4th row are the new 18.3 grain. When I switched to the new AEAs the velocity dropped. That may mean the mass went up. Somehow my two scales are missing so I ordered another but it won't be here until tomorrow. I know the old AEA 18.3s weighed 18.1 grains on my missing scale.
The key point of this post is the 3 shot target with the new 18.3 AEAs. I think it's the third from the left. That group is as good as I've shot with the old AEA 18.3s. It is at essentially the same velocity as the old AEAs on the top left but I had to increase the hammer spring some to get the new AEAs to that velocity. I was also falling off the regulator as I shot these groups. The group on the right in the fourth row is a little over 900 fps because it was after I refilled the gun. It is only a little worse than the ~895 fps group. The wind was about 6mph according to the weather service which undoubtedly affected groups at least a little in some cases.
I'm guessing the reason for the redesign of the 18.3s may have been the fact that the first design was not really 18.3 grains in weight. Not sure why it was released and then changed. But it doesn't matter if I can "fix it" with about 1/4 turn more hammer spring. Somebody suggested a retune early in this thread, I think they were 100% right. I kind of doubt it will fix the issue for everybody but I hope it helps some.
