Picked up some  Fed 9mm +p 135 gr bonded this SAT. I never saw it before is this one of the great new 9 stopping rounds? The box is LE marked  and I paid 20 a box .  I think every place is going 9mm now.

Not sure, never heard of it before and thought you had meant HST's in a new weight, but after google, there it is. I'd still use 147 HST's though.

The 135 bonded is only run a couple of times a year on the production side.  That's why it is not really known.  The other bullet weights are more popular but the 135s performance is great.  Had a winchester sales rep shoot some out of my carry gun at an LE trade show once.  He pulled it out of his gel and said "well thats good shit".  The federal rep there died laughing but even he had a hard time getting it.  Id like to know where you picked it up.  Id really like to pick up 500 or 1000 rounds.  IM me the info if you want.

Been around a while, it is a bonded bullet.  I have some for a rainy day.
