I’ve seen around 10 animals or so with the 77gr TMK below 1,800fps- there are several that I posted in this thread. All of them the bullets upset well and created very good, to excellent wound channels. It is very likely that the 77gr TMK is reliable well below 1,800’ish fps. However, in general bullets start struggling to upset consistently somewhere around 1,800 or so regardless of make. Being that is the case, until I see a bunch more, I would suggest 1,800fps as a safe bet.
