I went today with a fresh box from Cabela's (should be the new 10.0gr plus load) and a partial box of the old BE-86 loaded rounds. I did notice the new box had silver primers versus brass colored for the old stuff.

My hand Chronograph said the old stuff had a little more ooomph. Here is the data:
Old
EAA Limited Pro 4.75" 1214, 1224, 1228. Average 1222 FPS/ 597 LBS
EAA Super Match 6" 1267, 1260, 1259. Average 1262/ 637 LBS
Data from prior testing: SIG SAUER E10MB1 180 SIG SAUER FMJ 1,250 1,226 1,277 601 651 BE-86 8.8 Pretty repeatable!
New
EAA Limited Pro 4.75" 1213, 1198, 1199. Average 1203.33 FPS/ 579 LBS
EAA Super Match 6" 1250, 1250, 1261. Average 1253.66 FPS/ 628 LBS
Not a significant change, but I felt it enough.
I also re-tested the S&B 10mm FMJ with it while doing 10's. Results:
EAA Limited Pro 4.75" 1169, 1137, 1144. Average 1150 FPS/ 529 LBS
EAA Super Match 6" 1186, 1173, 1189. Average 1182.66 FPS/ 559 LBS
Old data: SELLIER&BELLOT SB10A 180 SELLIER&BELLOT FMJ 1,164 1,142 1,163 521 541 RAMSHOT SILHOUETTE 7.8
Pretty close as well!
Glad the Sig ammo is going in the right direction!
I need to try this. The early stuff didn't feed well and was light.
I just tried a box of this last weekend.
It's was the only in stock ammo available locally
Bought from bass pro for $27/box
Gun was the ria 52000 (6" bbl)
Altitude is 6500msl
Speed was fairly consistent @ 1250fps
Crony was about 8' from muzzle
Accuracy was pretty good at 5-7 yards, I did not test at further distances but I could shoot 14 rounds in a 1" group and 2-3 flyers (probably me)
Zero feed issues
My newer Sig JHP's are slower than the older ones were. My new ones are in yellow trays, old ones are in black trays.

yes I agree--- these were the yellow tray bullets and they clocked 1250 from my 6" barrel --- the SIG website says 1250fps but I would guess they would test rate them in a shorter than 6" barrel--- the speeds were very consistent though over my chrony when tested and I would consider the accuracy to be pretty good for factory range fodder and my first time shooting any 10mm (though the gun is one of the 2 most accurate pistols I own)
