Lapua Scenar Load Data - 11/11/20
Other than using VihtaVuori powder, I can't find load data for the 139 gr Scenar. I have H4350 that I want to load with.
So if I keep velocity under 2750 FPS I should be OK pressure wise?
Factory Hornady 143gr ELD X is giving me 2655 fps out of a 26" barrel.
Guessing 42.0 grains of H4350 may be on the warm side?
Here is a chart I found on the interweb that lists starting and maxiumum charges.
Bullet 139 gr Lapua, Scenar C.O.L. 2.717 inch
Bullet 9,0 g / 139 gr Lapua, Scenar C.O.L. 69,0 mm / 2.717 inch

Sorry about the formatting!
