This type of thread always costs me money. Thankfully not much this time.9.3x64 wrote: ↑Sun Oct 09, 2022 2:34 am I just received a set of these yesterday. Geez they are bloody handy, and cheap.
I load for three different rifles useing the same set of 7x64 Brenneke dies (two R8’s and a BD14). Adjusting the sizing die for three different rifles each time is a right pain in the arse. The problem is, even the tiniest bit of movement of the sizing die adjusts headspace more than intended.
Now I just set the sizing die at a fixed position and adjust headspace to the one thousandth of an inch with these shims. No guessing, they are dead accurate and work a treat.
I have been using the Redding competition shellholders, but these look much more convenient.
Ever since I acquired good measuring tools, I have been amazed at how much factory dies push back shoulders. EG: headspace considerably increased by FLS when compared to virgin Lapua brass.
I suppose die makers are less likely to get a complaint if their dies overly shorten cases than if FLS cases don't chamber.
