Thanks guys! Im pretty pleased with them to say the least...
NCShooter: Well the FIRST first shots were fired from a string with the gun mounted in a sled... The feeling there was a mixture of "its still in one piece, this is good!" and (picture Richard Hammond's voice from Top Gear) "a bullet went out!!!". But the next shots were pretty cool! There was a definite feeling of "Wow, these parts I've made are now a gun! it isn't a collection of parts anymore, its become a thing!"
Slimbo: The rings pictured are Talley rings. I'm not overly impressed with them though (they're not round and they dinged up my scope tube. And they weren't talking to each other well either. I mounted them on a 1" shaft and re-cut the dove tails(metal seemed awfully soft...) true to each other but that doesn't fix the tube denting issue... The scope I want to run for sheep hunting needed a taller set of rings anyway so I just made some myself(4140). Took too long but at least I know they're good... The last couple of days has been a loading/shooting frenzy! after screwing around with scope stuff the last month and playing with different powder/bullet combos I think I have some stuff figured out. Gonna load up another twenty and see if I can push back to 500m tonight...
FLHTCUI: I made the shell carriers(pics here somewhere). They're cut with the chamber reamer which means the round locks into place tight. So I cut a slot in the back of them and have a strip of oring in there to create a little give. Seems to be working quite well... I'll see how the oring holds up though.
