if it fits, it ships. I'm shoving .417 cast through a lube-sizer with a .413 die and they run nearly .414" after they pop out; they shoot just fine through my '95. I doubt another .002" is going to do anything other than raise pressure a bit unless it will not chamber. ymmv on that.
That was my thought also, a .413 cause you get spring back.
I tested these in my belted 405 and they shot [grouped ] well!
I also water tested them and they did not separate from the jacket.
