Hi guys I need a little help. I have searched this and have read a lot of different opinions on what exactly needs to be done to make it work so here is my dilemma.

I am building a 7 saum from a 223 hog hunter action. Barrel has already been ordered. Will be using a stock and bottom metal accepting accurate wsm size mags. Here is where I need a little help. What all is need to make the bolt feed,fire, and extract? Have read anything from just swapping out bolt head to swapping bolt head, firing pin, and baffle. If anyone has done this please let me know what all it took.

Thanks
