I’ve reloaded for several years now for another rifle but consider myself a novice. With that rifle I started with once fired nosler brass using RCBS FL die and found a load that suites my needs for that gun.
I’m now starting load development for a new 6.5 prc and using new lapua brass. My question relates to neck tension. My lapua brass measures .15 thick and neck diameter of .292. I started running them over a 6.5mm Sinclair exp mandrel to smooth out any dings. After running them thru, the neck diameter is .2925/.293. This is going to give me a neck tension of .001. If important, this rifle will be used for hunting as well as long distance at the range. My understanding is that loads for hunting, people prefer a tension more around .003. Would it not be wise to load and fire them with the current tension of .001 and then use a .291 bushing in my Redding die moving forward? Or do you think the change of .002 neck tension could negate the load development?
My thought is I could run them thru the die with a .291 bushing (with expanding ball removed) to tighten it up some and then start load development. I don’t want to go this route if it’s not necessary.
Much appreciated.
