6.5mm Lapua with 123gr. bullet

[lovec_1]

Guys, I've found few bottles of the H4350 and some boxes of Lapua Scenar 123gr in my safe.
Does anyone loaded this combo? What kind of speed I can expect? My rig has a 26" pipe. Thx.

At max pressure, QL shows 2983 fps. Data attached. As always, start low and work up.
