Went to the range today to try out a new load for my .308Win Tikka. This was the first bach I've ever loaded myself and I wasn't expecting much but left from the range pretty happy. Weather was ok, temp around 37F, no wind.
Hornady Match brass
Lapua Scenar S HPBT 168gr
44.3-48.2gr of Vihtavuori N550 powder
I had loaded the ammo in batches of three with ~0.5gr variation between batches to find the best powder charge and hit the sweet spot at 46.7grs. Next I'll start playing with the bullet seating depth, although the Tikka's original magazine doesn't give too much room to play with. With a OAL of 2.835" the rounds should still fit in the magazine and have the bullet touching the lands. Too bad I have to wait until spring to get to shoot at longer ranges than 100m
Also got test a friends AR-15 built for IPSC and SRA, now I seriously want one
100m, 3 shots, 46.7grs of N550, 0.3"
48.2grs worked well also, 0.35"
