I have a question for all of you with more experience than me. I am just getting into reloading and I have processed maybe 150 7mm Rem mag cases, about 500 nickel .223 cases, and some .308 and .30-06. All my dies were bought new and the trimmer was bought new. The problem I am having is after resizing the brass, the proper trimmer pilots do not want to go into the mouth of some of the cases. I am using the 28 for the 7mm, 22 for the .223, and 30 for the .308 and .30-06. Some batches that I run seem ok, but others the pilots will no going into the case mouth unless you force it to go in and then its an unholy PITA to get it back out. Any ideas?
