I enjoyed your review of the Caracal
I will actually be shooting a 'how to clean a rifle after 7n6 video' this weekend because I get that question all the time.... so stay tuned. If you watch my Tantal review I'm using 7N6 the whole time.
7N6 is a type of 5.45 round that is an excellent
performer in all aspects--reliability, accuracy, terminal performance, ect... that was made in insane numbers buy the Russians in the 70s and 80s. It's corrosive and that's about the only downside to the round. Sportsmansguide has it now for 1080/$139 shipped, which is 13 cents a round. To me the additional cleaning is worth it; especially with the quality of the round.
