Mate, go for it. I have had a hankering for a 257Roberts Improved for the last 20yrs. Finally scored one built up on a Browning A-Bolt fitted with an older model steel tube Redfield 4-12x scope.
Got a set of custom dies to go with it, a quantity of 87gn moly-coated reloads and two boxes of Winchester 100gn Silvertip factory rounds (for cases after fireforming).
I bought it last year but have had to wait till now to finalise the paperwork to get it from the gunshop. Can't wait to try it out.
