..............Oh I regulalry shoot 'naked' lube grooved boolits:
These are all the various types I've shot. Some GG types sized own and paper patched also. The best grease grooved boolits I've tried are the 2 on the right. The Lyman 457121-PH was made (and is still offered) for the Whitworth and Volunteer MLer's.
Those for 45 cal rifles dropping at .458/.460" have to be swaged hexagonal, or lubed and then run up through a push through die to make then .451". While the Lyman Postel and the Saeco #745 are similar, the Saeco outshoots the Lyman consistantly, even when both are scaled.
I used the Saeco sized to .451" to whack a 1' square steel plate at 600 yards 18 of 26 tries once at the range in Sierra Vista, AZ. Had the plate been 2' square (for 4 sq ft of area) I might have connected with all 26
. Actually, accuracy testing should really be done at 200 yards. The rifle has a 20" twist and these heavy conicals don't go to sleep at 100 yards. However, I'm an old guy and don't feel like walking out to 200 yards (and back) all the time, ha!
