I am wanting a 22br barrel for my TL3 and had some questions about forming the brass. Dies used will be Forster fl die. How much runout if any will there be? Will there be a doughnut created? Any other possible issues or is this as easy as lube fl size and load? Brass used will be Lapua 6br brass and I will have the smith use a Reamer that will not require turning the necks.
