noob reloading 338 lapua

[ELKMAN338]

Let the thrashings begin!!!! Noob to reloading and have a few questions a have a t7 press and im using redding type s match die set. My question is about neck size im assuming you measure some once fired brass through your gun to measure neck size in your chamber. I've watched a few videos were they say you should have about 2thousands under your chamber size for best accuracy. Redding told me to use a .365 titanium nitride bushing for the lapua brass if this does not give the right neck size do I just measure the difference and order another bushing or is this not that critical. Then the other ? is redding said don't use lube on there titanium bushing but it feels pretty stiff do you guys still use lube?

Lube won't hurt a thing. Measure your loaded round neck diameter. If it is .368 and you want 3 thousandths tension, use a.365 bushing. I usually have bushings one thousandths on either side of my intended neck tension.
If you have a factory chambered rifle, .002 clearance is highly unlikely as factory chambers are cut closer to maximum specs.

Also, measure a fired case. Rule of thumb is to add. 001 to .002 to that to get your chamber neck dimension.

OK got it thx for the info. I just received my pacnor barrel but still waiting on my vortex scope I might just throw my nightforce that's on my creed so I can start doing some load data. I have a dillion 550 for my hangun but I bought the t7 to slow me down and get some better loads for rifle. thx again
