I have been swapping around equipment lately. My Encores have all went away, and have been replaced with Nosler M48's. One of which is a 22 Nosler. The 22 Nosler is not nearly as fast as the 22GT, but it is still fairly impressive. I am getting 2800 with 77 SMK bullets, while you are getting close to 2900 with 88 ELD-M bullets. That is a pretty significant improvement in performance. I had never considered using my 22 Nosler on deer size game, but it looks like your 22GT did a pretty good job.
That is one good looking handgun, and looks to be another shooter for you.
