THE LOADS LISTED IN THIS TOPIC ARE WELL BEYOND LYMAN 49TH MANUAL MAX LOADS

With that out of the way here goes. This actually involves a couple questions and I am hoping you more experience Delta Elite gurus can point me in the right direction.
I was out doing load developement this morning and I am having brass issues. With all loads tested I am getting a crease in my brass about halfway up. It looks like it is from impacting the top of barrel when ejecting. Is there any fix for this?
Next. As I crept up the load ladder at 9.5 gr of 800x I started to get bulged cases. The bulging continued up until 10.0 gr and I quit there. It looks like there is a very significant part of the case that is unsupported. I noticed it was not a fully supported chamber when checking for OAL when loading. Odd to me. I reckoned Colt would have fully supported barrels for the 10mm.
This all leads me to my next question. I figure a new barrel with a fully supported and RAMPED barrel will eliminate all of these issues. The only problem is I don't know which barrel company to go with. I am looking at Bar-Sto, but they have 3 different ramp options. So the bajillion dollar questions are are Bar-Stow barrels fully supported and which ramp style would be best?
Any other barrel manufacturers you would recommend? The brass picture shows the bulged cases on the left, a new unfired starline case center, and the nicks/creases on the right. The 3rd picture shows the barrel where it is leaving the creases. Base off the locations of the bulge I have deduced it is the right side of the barrel that is nicking/creasing the brass on ejection. I could "break" that edge, but it still leaves me with the unsupported chamber.
