I’ve searched all over looking for a little bit of info on loading for .260 Remington using IMR 4955 (or 4451). I haven’t seen a whole lot of real world info yet beyond what Hodgdon has listed but I’m hoping someone can shed a little light.
Im just a few weeks away from picking up a new build that is on a long action. 26” Brux 8 twist on a Remington 700. My dummy rounds measured over 3”, of course that’ll change but I will definitely be able to seat bullets out long.
I have several pounds of both IMR 4451 and 4955. I have several hundred each of Berger hybrid 140s, ELD-M 140s, Hornady BTHP 140s and SMK 150s. I’m hoping to find something with 4955; am I on to something with having more case capacity? Also, anyone have any idea what kind of velocity to expect with the bullet seated out further?
