Hello Savage shooters i'm a proud owner of a new Savage 11g in .243 and I had some questions i was hoping you all could help me with.

1. What would you recommend for barrel break in? My last gun I did break in religiously and i could cover all shots with a nickel at 100. However i've heard that every gun is different.

2. I have heard of people replacing the recoil lug and barrel nut right way. Is this really necessary?

3. One of my friends also mentioned something regarding setting headspace to minimum. I have no idea what he is talking about. Any help would be great!

Thanks
