I use Jumbos in my 50 ft lb Ranger and they are by far the best I have tried in it.
I have zeroed it at 50 yards and earlier this week I took a woodie at 70 yards with just a mildot holdover. Awesome calibre and I am well impressed with the Galatian.
You can spend thousands and still miss a barn door or spend just enough and enjoy yourself. If you haven't got the talent to start with a million pound won't fix it. Whippet, Russell, a few bang sticks and a flat cap. http://www.smart-tech1st.co.uk
