just wondering. I recently bought a used (1985) contender. Haven't got a barrel for it yet. Have tons of .223 ammo, loaded for mini 14, up to 3200 fps. wonder if this is OK in my contender,when I finally get the .223 barrel. none of it is max loads, but close to it. they are just slightly over what the contender reloading manual calls for as max loads. what do you think? ( one ex. 55 gr BT using H335 25.0 gr) also, 55 gr BT with 26.0 gr Varget. thanks to all for the info. just don't want to damage the gun. Or me!!
