260, My old .300 has a 26" Lilja on it, and with I4350 it would shoot a 150 gr. NBTBT at just about 3400fps.. Somedays a bit over somedays a bit less.. It is a near max, load in some books, but shows no pressure in my rifle.. I used it on a sheep hunt in 91, sighted in 3" high at one hundred it dropped a bit less than 2 ' at 500.. Haven't tried the Accubond in that rifle, but if it is as accurate as the BTBT you would have the best of both worlds.
I did use it, the 150 Accubond, on an elk two years ago.. Again from a .300.. It had a much longer barrel, and the load was almost 3500 fps. I suppose the elk was 200 yards or so.. Not long range, but not woods ranges, dropped her right there.. The bullet performance was perfect.. However it did not exit.. On elk, I am not sure if I ever had a Accubond exit in .30 cal.Hope this helps.. There are much newer powders than I4350 but it has worked for me for about 50 years... Best of luck..
