nice to see a fellow .35 calibre fan , if you decide to get the work done you can realistically only better yourself ( not from calibre change only , i' m talking about the action and stock work ) the .35 is a great calibre and for woods ranges will outdo the .30 , but , wouldn' t it just be easier to trade for a .358 or buy one out right , they have very many savage99' s for sale at www.gunsamerica.com www.gunsamerica.com , let us know what you decide
