Yes and no to both questions.

That basically says that steel case does wear your barrel faster but you save enough money to buy a new barrel and still come out ahead.
Also, you will want to clean the gun after shooting steel case...
Whatever you are wanting to shoot just buy a box of it and see what it does for you. I think the barrel twist/bullet weight thing is made out to be a much bigger deal than what it really is. Especially if you are just going to use your AR for plinking at 25-50 yards. Now, if you are wanting...
I think machetes would be ideal.
Cheap(compared to a real sword), useful for much more than killing people, easier to maintain. Plus they are handy to have around before SHTF. If you get a sword it's just going to sit in a closet or in your safe until something happens, and then not until...
How do you like the fiber optic front sight? I love Warren Tactical sights, I have them on my 19 and 26 but with the tritium front. Plain black rear on both of them, the 19 is the regular Warren Tactical, the 26 has the Sevigny rear.

My bedroom is right by the front door so I will wake up if anybody comes in that way. I know this because my wife works third shift and it always wakes me up when she comes in. If they come in the back door they are going to knock over some clothes...
Always. If I ever need a gun for a defensive purpose there will be enough variables I cannot control, no need for me to add more stuff into the mix. I also do not carry guns with external safeties for the reasons NWS stated.
Pretty much agree with it. I conceal carry 99.793% of the time. The only exception is if I have been out to the hunting land I open carry there. So if I have to stop at the store on the way back...
Ask yourself what size wood you would need to cut the majority of the time. If you need to fell trees or cut large logs get an axe. If you are just going camping and picking up dead wood and need to split it or make into more manageable pieces a hatchet is all you need. Let the work you need...
