Magic tin of pellets?

I posted this picture a while ago about how at 50 yards, I had thirty one consecutive shots in the hole on the right and the next 11 (a full mag) went into the hole on the left. Those 31 shots can be covered by a dime! Now I know that's a bold statement and I'm sure some people are calling malarky and I can't blame them. So I've been determined to prove it and I went out and bought a scope camera mount, one of the Orien or Sebens or whatever they're called and it works pretty well with a little tinkering.

Well much to my chagrin, I can't duplicate the same results. I can get 8 or 10 to go in the same hole and then wham, a flier. Not a bad flier, but it will turn my group into fitting under a quarter and not a dime and that's not what I'm trying to get done. Admittedly it is harder maintaining a consistent hold on the gun when you can't shoulder up to the rifle because of the camera, so I tried taking the camera and mount off to use the same hold as before. Still no dice. Trying to figure out the variables, I realized the only difference was that those groups were shot with a tin of pellets that I had since run out of. Which leads me to think......

I'm starting to believe in "the magic tin of pellets" that your gun just loves. I have several other tins of 25g JSB Kings, and a few tins of Heavy MKII's and I'm slowly making my way through each tin but no luck yet. I know Ted is a fan of finding that perfect tin of pellets and then ordering a crap load of them directly from the same batch/die so that he'll always have them and I'm starting to think there may be more to that than I'd believed before. Thoughts? What other variables could I be missing? Could relative temperature, humidity, barometric pressure be contributing factors? I'm going bonkers trying to get this on video lol

31 shot group on the right, FX Royale 500, JSB King 25g, 50 yards benched, perfect conditions at about 7am and...............no way to prove it lol
 
I am by no means an accuracy expert, but still a grasshopper working on it, but at 50 yards I do not think relative temperature, humidity, barometric pressure would be measurable contributing factors. That's more like 100 yards and beyond. Rifle/scope cant can be a factor.

Assuming you can duplicate your rifle hold, and your MV is still consistent, and you DID have a magic tin of pellets, maybe try to weigh and sort a batch from a new tin of pellets. Then the only thing left (that I can think of) is the pellet head size. If the pellet head size is the only variable left then it's just a matter of time until you find that right head size that works with your barrel provided you have the right measuring stuff.

I would say that the last option that explains those awesome groups...is luck...but 31 consecutive lucky shots (I think) would be a mathematical improbability :)
 
I'm with you Cliff , I have 2 tins of pellets I received as a gift from a very good friend and fellow airgunner ( he calls them the "good stuff") and NO I won't tell you his name ')
They are the grey label JSB and they are unbelievable !! Zero flyers and groups that people call Bullpoop on often . My gun is still very accurate with regular JSB and AirArms but not like these .....I save them for showing off and when I wanna take pics of a group for a post on here .. Sounds silly as hell , but I carry them in a pistol case with my binoculars so they won't get banged up .
 
I go back and forth between AirArms and JSB pellets . A good sense part of me says they are made In same plant and probably no difference but they sometimes appear different so I'll keep buying both .. But the really Spooky good ones have all been JSB in 22 and 25 caliber . And in the one good 177 I've had its the AirArms heavies . But that's out of only one 177 so it is definitely not enough to draw any conclusions. I've heard a lot of guys rave about H&N and Crosmans pellets but I've never had any luck with anything but JSB pellets. Just my luck
