I had work up a load for my .300 Win. with the #3 Barnes data book and came up with a very good load.But this time I have to find a good hunting load for a friend's .270Win,and I don't have time to work a load and don't have the #4 manual.I will use the 140grs TSX and the powders that I could use are RL22,IMR4350,IMR4831.Can anyone help me.
Thank you

Barnes #4, 140gr TSX, R-P, GM210M:
Reloder 22: not listed
Reloder 19: 53.5 to 56.3 (start, max)
IMR 4350: 51 to 54.5
H 4350: (most accurate tested) 51 to 54
H4831SC: 54.5 to 58.5
IMR 4831: 53 to 56.5
Barnes #4 shows load densities with most of their data, a very valuable thing. Likeswise, Nosler. In general, powders giving the higher velocities with the higher load densities tend to have the higher accuracy. Having load density information is a good aid in selecting the better powders.
Hodgdon powders continue to increase their sales and appeal vs IMR when both burn rates are offered. This is due mainly to their Extreme Powder designation, which minimizes temperature/velocity fluctuations.
