Clearly not many options in this category. I have a Leshiy 2 now since the first round of 100 hit the states and I love it. Have had it in many configurations both low power and high power. Have had .22 in 65fpe and currently running a .30 600mm @ 105fpe. Problem is it moves a lot of air and take a lot to quiet it down.
My friend
@brawler1588 recently got a Huben K1 in .25 and after hearing his perspective, watching a lot of videos on it, having owned a 2020 Huben K1 in .22 for a bit, I would have to say it might be the best .25 semi out there at the moment. Easily tunable for 20 fpe to 100 fpe from what I have seen. Not huge or overly long and reasonably quiet due to a very effective shroud which can be brought down even further with minimal additional moderation.
BTW - I see your from CT. I'm your neighbor about 40 minutes north.
