Redding comp. die bushing ?

[finbox]

loading FGMM brass fired once from my Rem 700 tac.

loaded stock FGMM is .338
I ordered the .336 and the .334 bushings

using the .336 I get .333
using the .334 I get .331

Why are these so far off?

With a reloaded round it's .338

Will it hurt to have this much tension?

for a test on a NEW Laupa brass which is .336 when I use the .336 bushing i get .335

Does your bushing size your neck to the # on the bushing?...I thought that was the point.

I called redding and they said to send the bushing back for testing..but two bad bushing?

I have heard more than a few time that the buyer should measure the bushing because they may not be the size you wanted.

Another thing to think about is what are you measuring with? Nice calipers are still +/- 0.001" in the 6" range. If your calipers are reading on the low side the bushings might be fine/within spec.

What does your fired brass measure, I think your sizing down too much at once, I size in .003-5 incurments, my 308 fired brass measures .342, I neck size with a .339, then FL with a .336(Lapua Brass), my 260 fired brass measures .297, I neck size with a .294, then FL with a .290-.289, my concentricity is good.
