Thread: Quality "everlasting" .410 shells

I thought Id finish working up the 3/4oz load today so using only the one brass case I loaded 15.5gr of H110 which is 0.5gr over the 15gr book max in plastic hulls and put it over the chrono. It only gave 780fps, a very slight increase in velocity to the first test shot at 15gr but not much. I tapped the old primer out and reloaded it again with 16.5gr. This was closer to my 1100fps goal



Same case again loaded with 16.8gr of H110.



So close.. 17gr in the same case and just as I was ready to head outside it started pissing down.. that one will have to wait but Im quietly confident.

I have 8 loadings on that one piece of brass without any resizing and it still slips in and out of the chamber perfectly. The loads are such low pressure that the only movement of brass seems to be in the top 15mm so I cant foresee any sticky brass issues so no resizing is nessesary.




While I waited for the rain to ease I thought I work on the brass some more.
Even after the 8 loads the small ring around the top from the old 9.3x74R shoulder was still visible so I spun them all up in the lathe and polished them out with some wet and dry paper.





I then annealed the old neck section to relax the brass in its new form and soften it so the roll crimp doesnt end up splitting the mouths.



Into the tumbler for a few hours now to remove the sizing wax as its a pain in the ass with the super fine H110 powder that resembles fine glitter.. and they will come out all bling bling
