Official Nosler ABLR Load Data (300 WM added)

260 Remington
Ruger American 22"
Rem Brass (55.1gr h2o)
CCI 250
129 NAB-LR

Magazine Length: 2.850"
Distance to lands: 2.915"

I have found two loads that are solid at 100 yards so the node is close. Both in that 0.7 range center to center and around 2750fps.

42.1 grains Big Game
39.3 IMR4064

Worked up to 42.6 with big game and 39.9 with the 4064. Returned a slight cratering at the 39.9.

Soooooooooo bout 75 grains is a safe max! I run 77 grains behind Hornady 178 grain ELD-X. Thanks

Seventy-five grains would certainly be safe. I would work up carefully, watching for pressure signs, to 77.5 grains with the 190 grain ABLR. QuickLoad projects a slightly higher charge for the 178 grain Hornady ELD-X.
