celltech, when the screws were shortened, it did help and now the sliding is "sticky" when moved back and forth. I did try the bolts interchangeably and the 6.5 bolt worked well on the .223 rifle no problem. Then I took the .223 bolt and used it on the 6.5 rifle and worked well. So I then put some grease on the 6.5 bolt and tested it again on the 6.5 rifle and did way better. Started to slide much better... but as you mentioned, guess will only tell through many rounds as I barely only have 75 through barrel. By the way, I did install the spacer.
