A couple of tests with the 32grms..the one's I weighed were closer to 30grms...Browning Maxus,Teague 5/8th choke...average of 160 shot per cartridge...first pattern 30yds 95% inside 30ins circle..next 40yds..82%, I think the pattern would hold to 50yds!..and would probably pattern better with the 36grm cartridges!
