I put a SSA in my 6.5 Grendel and a SSA-E in my 5.56 precision AR. Both of these triggers are two stage. I found the SSA way to stiff in the second stage for my liking. I kept waiting for the break and by the time it came I was off target. My opinion is that it's probably not a bad hunting trigger where you tend to just get on target and pull but not if you are holding on a target and squeezing the trigger slowly. I ended up pulling most of my shots because I couldn't tell when it was going to break. The SSA-E broke much better and I knew when it was going to go but it was a little stiffer then I personally like in a precision rifle. This was the second time I've been to the range with these triggers and I walked away both times feeling the same about them.
I'm going to put the SSA-E in the Grendel. I think it will do well there and I'll go back to my favorite Elfman in the precision rifle. Don't get me wrong, Geissele makes a great trigger but triggers are as personal as underwear and these just don't fit me right. I have an Elfman sitting on the bench that came out of an old precision lower and I really liked it. If I didn't have it I'd be tempted to try one of the Geissele more competition minded triggers for the precision rifle. To be clear, the trigger is good but I chose the wrong one based on the web description.
