I have a fair quantity of older 5.56 ammo with the light 55 gr bullet. Not the newer NATO round. I have a Mini 14 that I bought around 1980 that I've never been happy with and am planning to upgrade to an AR. My question is what is the preferred rate of twist for the old 55 gr load? Is there a compromise twist that will give good results with the old load as well as the NATO load? Are there any chamber differences?
My second question: I have a bolt action sporter chambered in .223. I have been firing this old ammo through the bolt gun. Is this a bad practice? Any potential problems?
My third question: Why would I want a flat top AR rather than the handle? What are the pro's and con's?
Thanks for your help.
