I will not use a rifle that I can' t shoot well.I do however use 7mmstw' s and 300ultramags which are magnums.I am able to consistantly shoot 1/2" groups with all of my hunting rifles so being a magnum does not prevent a rifle from being shot accurately.Accuracy is a product of good equipment and regular practise and if you have the dedication you can learn to shoot well with most rifles and cartridges if they are well made and properly developed loads are used.
