Rifle: MS M1961 MCA carbine 6.5x54 MS caliber (1964) 18" barrel:
39 gr IMR-4350/160 gr Hornady RN/Norma brass/WLR primer. 5 in .87". Not chronographed yet. Estimated at 2200 fps.

39 gr H-414/120 gr Nosler Ballistic Tip/Norma brass/WLR primer. 3 in .54", 5 in .77". Not chronographed yet. Estimated velocity at 2550 fps.

Loads safe in late model Mannlicher-Schoenauer but take it easy and start lower in older (pre-WWII) rifles.
