The Mr. Bulletfeeder funnel has 2 different diameters on the expander plug. The first diameter and the 1st part that enters the case mouth measured at .353 diameter. There is a slight step half way up the expander and this is the next diameter measures at .358 in diameter. I cycled a couple pieces of sparkly clean 9mm brass through, both happened to be Federal. I was able to easily drop an H&G #50 wadcutter, .3575-.358, lubed bare lead, cast about Bhn 8.7, very soft lead. I seated one and it dropped in the casemouth with featherweight pressure, nice & square with out at all risk of shaving. I seated the bullet deep, almost 1/4 deep and only the last 1/16 of the base swaged down, well deep enough that case wall taper and stiffness was the root cause of in-case swaged bullets. The rest of the bullet survived no worse off and recall this is a .38 Special/.357 wadcutter in 9mm brass. Your quite safe with the Mr.B funnel. I do .355-.356 jacketed, copper plated, and coated bullets, not a trace of issue!
Hope that helps!
