what went wrong

My buddy Gurton has had trouble with those Winchester 10 gauge cases coming apart if they had much age on them. He got a great deal on a bunch of Winchester XX 10 gauge stuff several years ago but upon shooting some of the shells he found the brass and plastic were coming apart in weird ways. Now he's got all these good shells but is afraid to use them. These were all factory loads so maybe it ain't you Charlie, it could just be the cases. Were the ones you were using the big shiny XX type or the later muted color steel shot type cases?

destry tyey were the winchester x x the bright shiney ones. they are a few years old maybe several years old. you may have figured this thing out. i willhave to shoot a few more of them and reload them to the same specs to see what happens. ive not had a problem with them firing the first time maybe a secund loading is to much for hull....i hope i get to the bottom of this thing. charlie

Charlie,

I just checked the Alliant Relaoding Manual. Their max load for the Winchester Polyfomed with plastic base wad is 42.0 grains of Blue Dot, WW 209 primer, SP 10 wad and 2 1/4 oz of shot which yields 1165 fps and 10500 psi!

harry this is a very close load to the lymans load . do you think one grain of powder could have caused the problem.or do you think it could be the hulls. i know there can be a lot of speculations to the problems ive had with this load.i hope to find problem soon.will load up the load you posted and try it. i will also load up the lyman load and try it.thanks for the info. charlie

Charlie,

If you have access to a chronograph, it may shed light on things. I would back off a little rather than tempt fate with 43 grains again.
