I have a savage 12F in 6mmBR coming soon. I reload for several calibres and my dies are a mix of Lee, RCBS and Forster

I am looking at Reddding Comp dies vs Wilson hand dies. difference in cost about $50 including neck bushings and buying an arbor press
I have an RCBS rock chucker

Any advice / recommendations appreciated
 
Redding Comp dies are horrendously expensive for the complete set.

Get a Redding S-type full length sizing die and a Forester Ultra Seater seating die with the micrometer top. Essentially the same as the Redding at much lower cost. I have been loading my 6BR with this combination for years. Works fantastic.

If you look into it you will find the benchrest guys mostly full length size every time. There is really no reason not to.

The only reason the BR guys use the arbour press setup is so that they can load at the range and taylor the anmo to the conditions. Most of us don't do that so there is no reason to go that route.
 
If your 6mmBR has a standard factory chamber a bushing die "may" cause increased neck runout if the neck is reduced .005 in diameter in one operation.

I would start with the Forster Bench Rest Full Length Sizer Die 6mm BR for $36.99 and forget bushing dies. The Forster dies have the high mounted expander button that floats and these dies produce very little neck runout.

The Forster’s expander is high mounted on the spindle and floats, the expander button enters the case neck while the neck of the case is still inside the neck of the die. This keeps the floating expander from pulling the necks off center and inducing neck runout.

Below I ordered the Forster expander and spindle units for my RCBS dies and greatly reduced neck runout. Under the spindle lock nut is a thick rubber washer/spacer and this allows the spindle to move and self center in the neck of the case.

I also installed Lee lock rings with their rubber o-rings, this allows the die to float and self center in the press and again helps produce more concentric ammo.
