260 is my main hunting caliber... and it surprises me of all the folks using the slower 4350 and 4831 speed powders...
I use 4064 and RL 15 for all bullet weights of 130 grains and down...
for the 140s, if I am not using one of the above, then it is H 414 or IMR 4350 for the 140s...just because...
Mine see regular use with bullet weights from the 85 grainer HP Sierra to the 142 Sierra...
even tho they quite making them
my rifles were throated to do the 160 grain RNs also...which the old 260 could actually rocket them to an MV of 2800 fps with the right powder...but since they don't make them anymore it is a mute point...
for field hunting tho, still my bullet weights I depend on are the 100 grainers at 3350fps and the 120/125 Nosler's at 2800 fps ( yeah,I know I can get another 100 fps out of them... but the need hasn't arisen and 2800 is a lot easier on the brass in the long run..)
Where I hunt at woods range, then my standard load is a 129 Hornady at 2400 fps with a one to 4.5 power scope...
I've 5 different 260s in the rack... 3 factory and two custom barrels on Model 70 actions, with two more barrels that need mounting...
definitely a versatile cartridge...
for off season or just enjoyable plinking... I load it with 30 grains of RL 7 or IMR 4198, and use the 85 HP Sierra, the 90 grain TNT Speer or the 100 grain Nosler BTips, 100 HP Sierra and the 100 SP Hornady...
it is more than plenty of ooomph for a coyote etc at 200 yds.. which if plenty for the wooded conditions here in SW Oregon..
