Good evening, all.
I am working up a load for Hornady CX 270 Win 130gr, using RL19. Rifle has a 1:10 twist.
Q1: I cannot find any load data for that particular bullet with RL19. So I am planning to use the 130gr GMX data from my Hornady Manual (9th Edn. - I can't lay my hands on the latest one) as a reference starting point - I read somewhere that the load data for the CX and GMX were interchangeable, but now for the life of me I can't find that reference. Can anyone confirm that?
Q2: What is the lowest fps you have found that the CX will reliably expand at? I need it to work at 250 yds max for deer, and I read that Hornady recommend a minimum 2000fps for reliable expansion, but that seems awfully slow?
Many thanks.
