I’m shooting a 28 Nosler fierce carbon edge as my hunting rifle. Purchased 2 years ago bought 100rnds of Bertram brass at the same time.
I work out a load of 180vld, 80.5 retumbo. Work it up too high and bring it down to 3000fps with tiny signs of extractor marks but really light. Have had worse in other rifles with fast loads.
Go through my 100rnds of virgin brass in the last 2 years and come back around to the beginning and resize a batch and load them up (Redding FL die). Go to shoot and the bolt is exceptionally hard to close on almost all of them with the rest being moderately hard to close.
Back at the bench I do another batch this time trimming them down to same length as virgin brass and trying again. This time I tested the resized brass in the rifle before reloading. I’m getting the same results. Looks like there is friction at the base of the brass right where the full length die stops.
A virgin brass measures .0545” at the base and a once fired resized piece measures .0549” at the base. Measure both pieces of brass everywhere I can and compared and this is the only real difference I can find.
So what is the issue here? My dies? The fact that I’m over pressure then fl resizing?
Going to pick up a box of factory, fire a couple then run them through the die and see what happens.
