So let me run this by y’all. So in times past I had a bullet mould or two that made bullets slightly out of round with the narrowest section being undersized. I swapped them off without even trying the subsequent bullets.
I currently have a lee mould like this. It’s 429-240-2R. It is .430+ for most of its cross section, but just to the side of the parting line it measures .4285/.429 depending on mould temp and technique when I poured. It measures this I’d say 1/8 of the bullet.
So my query is, with my bore being .4292, will it lead? If that small part hits the land in the barrel it’ll be fine, but if it hits the groove, what’s gonna happen? Will the pressure from a land on either side make that small portion bump up? Will it only bump up if its a soft for pressure alloy? It is standard 44 special pressures, But would 44 mag act different? Alloy is ww+Sn, but I also use 50:50 ww/pb+Sn.
Has anyone traveled this road and save me the trouble?
I have 18 from ww alloy loaded to test, but I want to know what’s everyones else’s experiences are.
