[QUOTE="IHFarmer07, post: 2017326, member: 75397"] Do you have donuts forming inside the case at the shoulder/neck junction? This WILL make a huge difference. All of the rifles I use for precision and long range has a several step case prep with neck turning every time to get rid of the donuts and I have played with neck tension myself, it can be a hair pulling, $$$$ rabbit hole to go down. I’ve bought a k & m arbor press with a gauge pack to measure tension and with that I even polished the necks of 5pcs of brass to a shine! I could not get them to seat without maxing the force pack out on the k & m so I used my co-ax, with that, I had very good everything, es/sd and I think the group was awesome too but there is NO way I’m doing that to every piece of brass I reload!! In my findings on the rifles I’ve played with, high neck tension ends up with higher velocity most times with either an accuracy and es/sd loss or gain, low tension usually drops the velocity with either an accuracy and es/sd loss or gain. [B][I][U]YOU have to figure out what your gun/reloaded ammo combo likes[/U][/I][/B]. Trigger time never hurt nobody. In my playing with neck tension on the liter side it’s has been more accurate at times, but it seems to me that the liter the neck tension the harder it is to have all brass consistent with that tension. I just got done messing with my 6.5prc with Badlands Bulldozers and Gunwerks brass using less and more neck tension, I thought it helped but later in my testing my thoughts on it helping seemed to fall apart. I use a special die made by Kenny Porter, his let’s you use gage pins which is tool steel and is very very accurate on sizes. You can find the gage pins on Amazon.
