Nothing special, but it eats just about anything I feed it and is reasonably accurate. Been working with an array of 175gn and up for subsonic and am finally trying the Berry's 220gn this weekend. AA1680, and a similar surplus have been pretty good suppressed, but IMR 4227 has been so quiet that I am focused on it to see if I can get it to cycle consistently. At any rate, I am having fun learning.
