Morning, Daryl. That's very helpful, thank you. I'm familiar with the 16 pages on the AR15 forum - it got me interested in the first place but the sheer number of posts and ideas just wore me down.
Your suggestions have put me back on track, thank you, so I shall be scouring the RS components catalogues and certain other sites for components today. I'm looking forward to coming up with a device of my own.
Your comment about using only clean cases has been noted by others, so it's clearly important not to chuck dirty brass on the annealer.
Also.. great shooting in the your CAS video........ "hey, cowboy, walk this way.." classic
Cheers!
Parts all stall available and ordered....
