Powders for 260 semi auto

[Lance B]

What powders and amounts do you use for your 260 semi auto rifles. I will be using Lapua 123 and Lapua 139's. cci primers and Remmington brass. Not much in the reloading section for semi-auto's.

Thank,
Lance

I had a hard time with the H4350 and still working on a load.
All the loads suggested on this board was way to high for my AR GAP 260.

A friend offered me some Vv N550 and got 1/2moa or less, with 38.8 to 39.5grs using the 139Scenar Moly. No signs of pressure.

Rem brass, CCIBR(test with Wolf soon), @ 2.810"

Yes Vv is expensive and I would prefer a load with a cheaper powder.

Speed unknown at this time
