180g lee round nose mold, gas checked, lee alox lubed, trailboss powder.
start at 11 grains and work downwards till you get subsonic, i went as low as 6.5 grains and still had consistant ignition spat them out of a remington sps varmint 26 inch barrel at 680fps, but that is not recomended due to potental risk of detionation.
i think i hit subsonic at 8.5 grains and it was plesently accurate. around the 1.5 inches.
i didnt bother with: magnum primers, enlarged flash holes, collet neck dies, oversized expander, turned necks or any other hocus pocus.
but i suppose you could go to the effort if you need better than 1.5 inch groups.
one thing i did tho is i slightly belled the neck to allow easy seating, then ever so gently crimped it back to flush when seated, so as not to damage the lead.
you gotta go gentle with the projectile as the lead is so easy to damage.
