I am going to ask what will appear to be a simple question, if it has been taken care of before then please feel free to post a link to my answer.

I can find all kinds of Savage model 10 series rifles in 243 and 308, once I find out the exact hole spacing how hard it it to convert a 308-243-7mm08 to a 223 based (223, 222, 300 BLK, 7.62x40) rifle. I know I will need a new bottom metal and bolt face but is there any particular 10 series that is easier to convert? I will be looking for a used rifle or at best a hog hunter if they are still top bolt release.

Thanks for the wisdom guys!

Josh
