I used 130 accubonds and swift s2's last couple. and 120 tsx will kill as well. All depends how far and what want to shoot. Partitions haven't been known to be super accurate compared to stuff out nowdays.
with your slower starting speed maybe a 140 will hold velocity better at distance, you'd need to run some numbers.
I want to try the 127lrx as an all round go to, seen a post on us forum where they tipped a few over way out there with it and seemed to work.
