My boolits are weighing from 411-413 grains from my Lee 405gr HB die is this normal my mix is 1:20.

I'm gonna just throw this out there but it's my understanding that the molds are designed basically using Lyman #2 alloy which has a lower lead content than your 1:20 alloy. Less lead equals less weight. Since your alloy is 95% lead (+/-?) instead of 90% I'd expect the weights to be slightly higher than stated on the mold, especially with a heavy boolit like a 405.
I don't think I have ever seen a mold throw a boolit that weighed less than it was designated on the box.
no problems, your gonna work your loads up in your rifle with your components. [shrug]
if your worried about the weight spread do the math and see what the actual percentage the spread is.
I doubt you'll notice 0.25% difference.
I haven't seen what Lee uses as a "standard" alloy for their mold spec. Different alloys, different mold temps., different melt temps. will result in different weight and diameter...
My Anchor is holding fast!
I have a Lee C112-185-1R that Instead of throwing .112 boolits at 185 grains it throws .114 boolits at 186 grains using wheel weights. Its not such a big deal for me though, the weight is fine and I was actually thinking of upgrading to a .114 mould. I lucked out.
My only fear of death is my wife will sell my firearms and casting equipment for what I told her I paid for it....
From the coasts of BC and Newfoundland Labrador, to the smallest crevasse in the hills of Afghanistan. Support your Canadian Troops!
Once I get the mold broke in, heated, etc, I never see them fluctuate more than 1%, usually it's about half that or less.
Warning: I know Judo. If you force me to prove it I'll shoot you.
Sapper I would consider it a double win to have that mold. The weight is dead on and the size is perfect!
