Sig 365 ammo?

[Stafford]

Sig makes a 365 fmj 115 grain with a published velocity of 1050. I would assume this is out of the 3.1 inch 365 barrel. What type of velocity would likely be produced from a 4 inch or 5 inch barrel?

Back when you could actually get this ammo . We came to the conclusion that the "365 Ammo" . Was just a marketing gimmick. The ammo marked 1185fps was the same as the one marked 1050.       You may get different results.
