Thread: ADI book max’s

When needing max internal volume in the .223 consider not FL resizing and only size half the neck, also tap the brass once filled and the powder will settle

Sizing only half the neck has the added benefit of centring the projectile to the bore, as centring from a shoulder is erratic.

With long throated Sakos and fluted Tikka ultralights ( Sako finnlight barrels) 5 thou off the lands ammo lengths are very very long which also increases powder capacity

Another trick is go on 6mmbr.com .223 page and they have a chart with different brass manufacturers showing the internal volumes.

With the .223 and 2206 it’s very possible to run into pressure issues, much more difficult with 2208 as often you just can’t fit enough in

There are always exceptions so work up to full loads watching for the usual pressure signs

I use Lapua brass which has lasted well
