20 VARTARG concentricity without the correct die

[oneshot 66]

I neck turned Lapua 20 VT brass and it was +-.001 on my concentricity gauge when I started. After loading it was .001 to .004 on the bullet. One shot brass, neck sized with a Redding bushing neck sizer to .228, but used a Hornady 204 seater that does not guide the brass like a Forster or Redding Comp. seater. I loaded 19 Bagder with a Forster seater and the concentricity remained thr same. I'm thinking I should buy a Redding Competition seating die to solve this problem. Any input would be appreciated.

I use a Comp seater for my 221.

I can only find 1 in 20 VT, that's the Redding. It's expensive!

Redding is over priced IMO. I’ve been slowly moving over to another manufacturer after using them strictly for my whole reloading career.

Have you considered switching to L.E. Wilson chamber dies? The cost of one die and a Sinclair arbor press would set you back about the cost of 1 Redding die.

Look into it. Best decision I’ve made in my reloading setup.

Might not help.

Is that the runout, or the TIR? I use Redding Comp bullet seating dies for almost everything I load. I focused on case neck runout and ass-u-med the Redding Comp dies would seat the bullets straight. My case necks are less than 0.001" TIR, after seating with the Redding (many bullets many calibers) bullet TIR was 0.002" low, and as high as 0.005-0.006". I started seating my bullets in 3 steps, rotating the case about 120 degrees. Bullet TIR is now 0.002" max.

Suggest you try seating in steps with your current die, and see if that helps. Zero $

jepp2,
My current die is a Hornady 204 seater that only supports the projectile, not the case. I think if I didn't push all cases to the right and hold them, they weren't aligned. I think I need a seater that supports the case sides and keeps it aligned.

Go with what you think will work best.

There have been a number of studies that have shown the standard seaters produce surprisingly concentric loaded ammo. I'm just trying to share what others have found. And if you are talking TIR, your numbers beat my Redding experience.

Joe,
Wilson doesn't make any dies in 20 VT.
Thanks,

Just spoke with Wilson on personal business but while I was on the phone asked them about the 20VT. They do make dies, case holders and gauges for the 20VT. Actually have a seater in stock ready to ship. Goodluck with your endeavor.
