RE: What is the best woodchuck gun?
The 22-250 will work well for you as will the 243,the heavier bullet weight in the 243 will be moved less by the wind but it will recoil a little more because of that same fact.In a heavy barreled gun the recoil is very light and while worse than a 22RF it should not be an issue for you.I always used a 22-250 and my Dad always used the 243 in a similiar type varmint gun and we seemed to do about equally as well.In a 300yd plus shoot on a breezy day I could see the 243 having an edge.I just sold the 12FV savage two days ago to get my current one and the laminate stock is pretty much the best of both worlds while the savage synthetic could use a little stiffening up in the forend to really make it prefect.Good Shooting and Choosing!
