Harvester green crush rib sabot??


Button Buck
Someone gave me a box of Hornady 44 cal. .430 diameter with green sabot.
The outside spec bullet in sabot runs .507
These will never go down my Thompson center impact.
I like to any one know using harvester green crush rib sabot what will it mic out
I need to stay at or under .503

Can't help with actual diameter since I am at work until tomorrow evening, but my son's Impact shoots Hornady .44 cal great with 80gr BH and green crush rib. Loading pressure on ramrod is about as good as it gets; easy enough to load but not too loose.
