So I have made my choice and it is the Tika stainless lite in 223, this rifle has a one in eight twist, which is sapposed to handle bullets up to 80 grains in weight. My question is how will it handle lighter bullets like 55-70 grains in weight? is it too fast of a twist rate for the lighter bullets? I really like the 60 grain partitions and 65 grain game kings. I do want to experiment with heavier 70-80 grain bullets also.
