I'm a new member to the site and I appreciate all the info that is available here. I want to build a hunting rifle in 300WSM on a 700ss sa. and after doing a search on this forum I'm aware of some of the limitations such as bullet length and feeding. I plan on keeping my bullet weights in the 165 to 180 range so will this still require altering the magazine (wyatt) and is there any machining or altering the stock to install what I need? Also can feeding problems be avoided by keeping less than 3 in the mag? And finally is a factory WSM SA different then any other SA in any way?
