I have a suspicion that the reason the bolts cycle badly is the well worn clips. Without any rounds in my rifles, both cycle just fine. Put rounds in them and it's a whole other story. I just fired my 7.35 a few weeks ago and half went fine, the other half hung. I think if the shell is loose and does not get in the bolt head just right, it won't chamber properly. I had one round that went in but the bolt wouldn't close. It dropped right out by turning the rifle up so that wasn't a problem but had I tried forcing a second round in thinking there wasn't one in there it could have become a big problem.
