I have some 7-8 pound rifles that swing, balance, and point great.

I have a 9 pound 416 bolt(scope included) which is more fun to carry than my heavier guns but a real eye opener to shoot.Indeed ANY gun that smacks the shooter hard gets old.

I do not have enough "gun time" on the range to definitely determine my preferences re:Doubles.Indeed I have only one Double-a 500NE.

400 NE
You are a wealth of information and would have hundreds of other Double shooters agreeing--

It may be that there is no need to build a well balanced Double lighter,stronger,and shooting a higher velocity round but I would sure like to shoot enough Doubles to know viable options.Until I shoot such a gun it is hard to determine personal preferences.
