I have been shooting 100 grain core lokts in a .243 with no problems but decided i would try some hornady 95 grain sst.Every hornady i fired stuck in the chamber and i had to take a cleaning rod to knock them out,could it be that they are loaded too hot for this rifle?I tried to look up how to polish the chamber from the FAQ section but the link wont work.could some share with me the best way to polish the chamber?
