Hello everyone. I have been looking into the .17 centerfire calibers and am thinking about building an ar-15 chambered in 17-223. Does anyone have any experience with this caliber? I decided on a 17-223 solely because i have buckets of lc 223 brass. Should i go for a different caliber? Some say i can form 17-223 brass by just running a 223 brass with alot of lube into a 17-223 full length size die and viola! Is this true? First hand experience on this matter would be greatly appreciated! Thanks in advance!
