Larry - no leading problems at my place - but I am shooting new barrels
mix is about 50/50 soft lead and wheelweights with a tad of linotype - test is just scratch it with a 3B pencil
not much tin in that mix. - gets good expansion in soft dirt at 100yards
I like that LEE 405 HB but I modified it some
milled the nose flat for safety in my tube mag guns and lost the HB so I could use a wad under it still weighs 405gr
Also modded a second one by lengthening the base plug - lost one lube groove and driving band it drops at 335 grain
Its a nice profile and nice big lube grooves
