Realize this post is a little old, however a lot of questions as I put my 450 together (AR Platform). I do have a little experience reloading and understand head spacing problems with a straight walled case. It has been mentioned in other posts that most manufactured brass is less than the spec for the cartridge, e.g. Hornady brass runs around 1.65” and Starline Brass runs a little longer but still not to the spec of the 1.70”. Then this leads me to why not use the parent case to make 450 brass, .284 Winchester, but it is sounding like a nightmare reaming, turning, squeezing down bullets, broken extractors etc.... The first of many questions is just suck it and accept that you won’t ever properly headspace unless you posses a small fabrication shop?
When I load (sane) for a 40 SW and 9mm I measure a few cases call it good, jam a primer, pour powder, mash in a bullet, pull trigger, bang, hole in paper, approach the 450 with the same attitude?
On a lighter side excited about the thumper!!!!
