Spro Barrel Swivels (discrepancy) ?

[fish raptor]

I am a big fan of the Spro terminal tackle. Love their snap swivels and barrel swivels. Very small but very strong and it is generally agreed upon that they make the best. They very pricey but I don't loose many so I think they are the best choice.

I ran out of barrel swivels for setting up some rigging for Salmon trolling on Lake George so I ordered 2 bags of #2's (65#) and 2 bags of #3's (100#).

I was VERY surprised when I got them that I COULD NOT tell ANY difference in the #2 compared to the #3 sizes. Side by side with lots of light and a magnifying glass they were ABSOLUTELY IDENTICAL. To take it one step farther I had a micrometer to I mic'd them up (both rings on each end) (.012) were IDENTICAL to one another and WIDTH of BARREL itself. (.177) were identical on both.

If you emptied both bags out on the table and mixed them up it would be physically IMPOSSIBLE to tell them apart ??????

So...... I went into my terminal tackle box and grabbed a #100 Spro snap swivel and a #60 Spro snap swivel and you could EASILY see the difference in size between the two, the barrel was considerably bigger on the #100 than on the #60. (see picture included)

Not sure but I wonder if it was a Friday when they packaged these barrel swivels and somehow they put the smaller #2's in the #3 bags as that is what is appears.

Unless their is some "metallurgy" differences that make on stronger I would guess someone screwed up at Spro.

Has anyone encountered this scenario before ?

I'm going to "bet the farm" they made a mistake.....
