{sigh} Mass produced slugs - weigh and sort them too? ;-(

lol . . . I've recently been experimenting with various slugs from different vendors (AVS, Griffin, NSA, FX, etc . . . ) and have most recently been using a batch of the JSB Knock Outs. Now with any and all of my pellets (JSB and/or Air Arms) - I typically always weigh and sort them based on popular consensus from you guys in here. I've, purely out of curiosity, plunked a slug or two down on my scale just to see how it weighs vs. what it's sold as. Frankly - they've been amazingly spot on. I don't believe I've done that with any of these JSB's though - I've just been shooting them straight out of the tin. See attached picture. I shot it this morning - 100 yards. Unfortunately I don't know / remember what the order was that I shot them in - I was pressed for time as I had to cut out and get to work. (lol) I'm not sure if I started out bad ( the wide ones out in the 6 and 7 rings ) and improved with the last 5, or visa versa. It kind of smacks of weight inconsistency though - esp the three in the 6 & 7 ring. They're all ( consistently ) low.

I may run a bunch of them across my scale later on this evening after I get home from work just to see / curious. These, being mass produced, may indeed have some more inherent inconsistencies than the smaller guys like griffin, nsa, avs . . . who are likely (?) able to maintain higher tolerances. (?)

Oh yeah - I only had 9 shots in the magazine. That's why only 9 on target (if curious ).

( it's now later and I'm home from work - dogs have been fed, I've been fed, etc . . . ;-) )

Well this is irritating. As mentioned in my original post re: running the few that I still have left on my scale from this one tin that I bought to test these out - these things are just as, if not more so, variable in weight than pellets. (??)

Numbers: I clump weights into the 1st decimal - ie; 25.00 - 25.09 will all go into the 25.0 tin, 25.10 - 25.19 - into the 25.1 tin, and so on . . .

weight | number of

25.0 - 1
25.1 - 5
25.2 - 10
25.3 - 23
25.4 - 14
25.5 - 9
25.6 - 3

They're spec'd at 25.39 so having the majority of them coming in at 25.3x range - ok. But still there is only (quick math . . lol ) 65 of them left from this tin and that, to me anyway, is a fair amount of variability in weight. I measured seven different weight ranges across just 65 slugs. My AA 10.3's (so far) only span across five different weight classes - and I've sorted a couple thousand of them - for the local FT season that hasn't, and likely isn't, happening this year. :(
