260 Rem. 139 gr. Lapua Scenar Hodgon Superformance

[Alaskaman]

Hi,
want to share my load.

caliber: 260 Rem.
virgin 308 Win. Winchester brass downsized (56,1gr. H2O)
139gr. Lapua Scenar
CCI BR
COAL: 2.807
Barrel: 26 inch LW match
Twist: 8
Powder: Hornady Superformance
46,7 gr. = 2850 fps
47,2 gr. = 2883 fps
47,7 gr. = 2925 fps

All loads with easy boltlift
A little bit cratering on the primer maybe due the fireforming of the virgin brass.

This load works in my rifle, be careful.

I started loading the SF powder in my 260 with 123 scenars. It is running at just under 3100 FPS. No presuure signs at all and not near a max load. At 500 it holds a 1/2"
group and a straight 1/2" at 100. Will be testing the 136's in the near future. I think this powder can be pushed a bit more and it seems to be forgiving as far as pressure
building rapidly.
