So I’ve read all of this thread and am a little over 100 pages into the .223 thread. Good info and has already caused me to pick up 500 77gr TMKs, 200 147 ELDms, and 500 106 6mm ELDm factory seconds that are used in the TAP ammo. I don’t even own anything 6mm that can stabilize them yet, but they were cheap.
Anyway, I would like to hear what bullet suggestions there would be for a .260 with a 20” 1 in 9 barrel at 500’ above sea level.
Using Berger’s twist rate calculator the 130 TMK is iffy here but would be fine above 5000’. How about the likes of the 107 TMK, 100 or 120 ELDm, or 120 GD?
The flat base cup and core bullets work well enough here as shots are close. Ultimately though this rifle would likely be a contender when I finally make time for aoudad. I’d like to find something with a decent BC and good terminal performance, that my rifle will stabilize here so I can work up a good load and practice with it a bit.
Perhaps it’s just time to look into a new barrel though.
