I just started reloading 6.5 creedmore and having multiple problems with first batch. First thing is they aren't feeding right. Thay jam half way and i have to pull bolt back slighty then forward this gets round to chamber. Round hard chambering , bolt hard to push the last 1/8" and hard to close. Ejects fine. Second problem is theres burn marks on neck and heavy burn ring at bottom of neck. I'm using once fired hornady brass, full length sizing, cci primers. I trimmed cases, and started at lower end of powder scale. I also loaded 2 different bullets and 2 different powders with same results. Bullets were hornady match, and burger hybrid, powders were hybrid vl100, and hmr4350. I'm shooting a burguera bmp.
