Wondering what the lightest contour you would go with that can handle a decent rate of fire. The wife is getting more into long range and is signed up fora couple classes this summer (its good to hear someone else tell her what I do). She has been shooting her hunting gun but it has a skinny barrel and heats up pretty quick. Thinking its not what she wants to take to her 5 day class. She's not a pussy but is pretty small and I hate to see her bogged down, especially with positional stuff, which is in the curriculum. Im thinking #3 or #4 sporter and 20-22" would be a good place to land. Probably stick with .260 rem, same as her hunting gun. Thoughts?
