I'm looking for a new match rifle. I was originally looking int othe 260's but a guy is wanting to trade me a 243 AI on a stiller action with a Rock creek 8 twist barrel. It is in a greybull precision stock but If I don't like it I can always put it in a new stock. I have never owned an Ackley is there a great benefit of going to the Ackley in the 243 and is the 8 twist fast enough to stailize the 105 -115gr bullets that I would need to compete.
