I necked all my brass down with a 302 bushing, then 289, expanded with 263 mandrel, neck turned to 0.014 thickness as my rifle is chambered with the original max reamer that had a 296 nk, the newer revision has a 298 neck for no turn. I just can't vibe with Cases that don't slip a bullet in the neck after firing.

The new formed brass has a thinner neck wall than the original brass
So now the 296 chamber is a no turn with the new brass? I got 100pcs from your last shipment I haven't inspected the dimensions yet, that's good to know!

yes, you should have .004-005" clearance
Rich, should I check with HCA & see which Reamer they have before I order bushing?
I was gonna get brass prepped & ready.

If you have the new brass, you should be fine.maybe get a .290" and a .292"
Mike has the rev1 reamer. He chambered 2 rifles and one forming barrel for a friend and I.
Guess I'll measure up & size some brass & see which reamer to go with accordingly. Need to find the best combo of Reamer neck dimension, neck bushing size, for neck tension
& clearance for bullet release, for the
New Brass as well as the Next Gen Brass.

Id go with the Gen I and new hrass. it leaves a little room to turn if you want.Guess I'll measure up & size some brass & see which reamer to go with accordingly. Need to find the best combo of Reamer neck dimension, neck bushing size, for neck tension
& clearance for bullet release, for the
New Brass as well as the Next Gen Brass.
Next run of brass MAY be a little thicker?
Thx. Rich, I'll go that route.
