Thread: how little reworking of the brass while reloading is necessary

I just running another 100 Hornet case across the Lyman case prep machine, and think about whether I would risk not doing case prep as per the Bible??
Yeah but nah.
The milk bottle shape of the Hornet stretches with each firing, so case trimming is a MUST! By explanation, trim length is 1.393, max is 1.403. Some I have acquired measured 1.422!! Go figure how that fitted? Would I put an over length case in my rifle? HELL NO!
But the thing that most concerns me about not following approved process, is the flash hole. I've seen flash holes so blocked with crap that they are 1mm or less in diameter. The handheld Lyman reamer takes the hole out to 2mm. How can you get consistent ignition if the flash hole is gooked up? Flash hole cleaning is a MUST at the bench.
The other thing I read about flash holes is they are either drilled or punched. Either leaves rough detritus around the inside of the hole. I've cleaned every flash hole of every round I've loaded. Sometimes, on the inside I can feel the tool riding over a "lump!" Once the lump is dislodged, the reamer rotates smoothly. I reckon that lump is about the same volume as a grain of 2207. On a small capacity case like Hornet, that might have some effect on consistent performance?
