Wanting to put a 4.5-14x50, Leupold 54660 on my custom Rem in 257. It is a fairly large scope. Rifle specs are Mcmillan Classic stock, standard fill, Hart #4 fluted and finished at 26" and lefthanded. What one piece base and rings would be recommended for holding that scope without being overly heavy? Rifle without scope goes around 7.5 pounds. Suggestions as all I have run are one piece lightweight Talleys.
