Good morning, for my first post on this very informative (and entertaining) forum, I;d appreciate some advice on the following: In the next few months, I plan to pursue my 1st-ever custom rifle. While I am primarily looking for a long-range varmint/deer rifle, I would also like to have a decent paper puncher as well. Of the 2 calibers I have listed, what would be my best choice. Also, what would be the best all-around barrel lengths and twists.. Thanks in advance for you input.
