When this round came out powders that burned slow enough were not available,now they are .I own two rifles in this caliber ,One is a model 70 with a 6.5 to 20 leopold scope it easily stays under an inch at 300 yards.The other is a Ruger model 77 with a 4.5 to 14 leopold scope its not the shooter the winchester is but it is he!! on whitetails.
Both of these rifles have hundreds of rounds thru them with no wear.
