I recently acquired some headstamped 585 AHR brass for my display boards. .585" bullets will not fit. The necs mic .580"
Anyone have some .580" bullets I could buy. I'd only be looking for 20. I only have 5 pieces of brass, but if I can get the bullet issue worked out there are more available.
Thanx for your help

It is just sized brass, isn't it?

Just seat the bullet in reloading press or any other suitable press or use any other appropriate method.

Just my opinion.

Is this an especially rare bird? For some reason my googling 585 only brings up the Nyati.

The bullet there appears to measure .585" but as it evolved from the .577 NE and shares its diameter, we see that calibre nomenclature can often be nominal, sometimes weirdly so as in the 38 Special. In the case of old-timers, rifle bores and grooves could also vary greatly. I seem to recall that the groove diameters of some Martini-Henry .577/.450 rifles could be .465" or larger, which might help explain H&H's response when the .450" bore was banned in some colonies.

ask bitterroot, a poster here - he owned AHR and invented the round -
basically it's a better, but like, 585 nyati, with a different neck, shoulder, and rim diameter, but it IS a .585 bullet
