Home Forums Hunting & Shooting Hunting Rifles Howa Alpine Mountain rifle 6.5 Creedmoor.

I gave the Hornady 129gr SST's a try today with Superformance powder. This was a 5 shot group at 200 yards. I didn't load enough of them to take it out further. I was useing once fired factory ammo brass, full length sized that I purchased from a member here. The group shows it wants to shoot. So I came home and just loaded up some Hornady brass that has been fire formed already to my chamber and I think I'll take it out to 300 yards in the AM and see how the load shoots. It shoots about 3/4 MOA flatter at 200 than my 140gr A-Max load.
