at this point this is a thought experiment, but its driving me crazy so i thought i would look for the thoughts of others.
at some point i wanna make a sub sonic 223 load. however i do NOT want to worry to much about powder position load density ect. beyond what is already necessary in reloading. google has yielded a little info but nothing i would say is solid.
1. packing the case with filler is one route, however it can leave residue in the barrel that may not be good for the next round going down it
2. fluffy powder is the route i would like to avoid.
3. machining cases from bar stock with a simple hole down the middle. -cost vs payoff kills this one
these 3 are the ones i dismiss i have come up with 2 ideas on my own but am looking for pros/cons new ideas or what ever
1. fill the case with an epoxy or other liquid filler - i have seen a few that are fairly cheap and withstand high temperatures, used to repair automotive exhaust systems. then drill you the center from shoulder to flash hole
2. expand the neck and use inserts of some kind, such as metal tubing. then size it back down. with this method i was thinking card board tubes would be pretty cheap to make, similar to what you would see in say fireworks, life of the liner would be limited to a few firings.
both ideas would require a small amount of flexibility in material choice to allow for resizing. the epoxy idea seems to me to be the path of least resistance.
i am well aware this will not cycle an ar, more of thought experiment anyway. i also know that a 22lr will do the same thing, the point would be to be able to go from subs to full power with just a mag change. as well as to shoot heavier bullets. Also it would be neat to make a pseudo wild cat. i thinking case capacity would be best cut in about half. basicly having about a 224 hole going from neck to case head.
thoughts, comments, other ideas?
