I bought old Winchester Model 70 caliber .300H&H along with new Weaver bases designed for that rifle. I also found perfect scope which I plan on buying. The scope is SWFA SS 3-9x42mm Mil-Quad reticle. The only downside is the scope has 30mm tube which results in weight of 19oz. My question is are the bases plus Weaver quad rings strong enough to support this telescope? Thanks.
