what went wrong

charlie cleveland · 01-09-2010, 06:11 PM

i was shooting some 3 1/2 in 10 ga loads today.the gun i was using was a ithaca mag. ten auto. ishould have stated these were reloadsthat ihad reloaded myself.they were reloaded by the manul andall things done right to my knowledge. the shells shot ok but the brass at base of shellsplit on 6 rounds right were the outer edge of the rim.the last round that i shot the plastic of the shell stayed in the chamber. the brass had come off theshell completely. i then went and got 3 new shells ihad not noticed as of yet that the plastic was still in the barrel. i tryed to chamber a round but it would not chamber this is when i noticed the plastic hull still in barrel. took a while to get it out with a long rod.this was kind of a scarey thought if that plastic had ofwent up the barrel a little faruther and round had chambered.... has any one ever had this to happen to them. or any body got any ideas to what caused this. i haved decided to get me a 3 1/2 double barrel to shoot my reloads in anduse onlyfactory loads inthe automatics.... my reson for doing this is be cause you can see down the bore of a double a lot easyer than you can of the auto.. hope someone has got some answers... thanks charlie

My guess it's the shells you are reloading. Try a different hull and double check your recipe.

Tell us what components you used to reload the 3 1/2" 10's and where you took the data from. Shame about the shells comming apart and damn lucky finding the stuck plastic in the chamber. I was in the blind with a mag 10 and thought I standing next to a 3 inch 50 doing rapid continuance fire.

the 10 ga loads were taken from lymans 4th edition reloading handbook. the load i chose was a2 1/4 ounce load. the the hull used winchester polyformed case..paper base wad 6 point crimp...powder was blue dot 43 grains primerwin. 209 one rem sp 10 wad... velocity 1193 pressure 9600 lup. the hulls had only been reloaded one time actually 2nd time factory loaded first time. after the mishap i had with them i fired 3 factory loads thru gun and examined hulls they were in good condition. i will go back and check my reloading teniques i could have done something wrong.im very carefull with my reloading all of myweights were weighted on good scales. hope i can find out what went wrong thanks charlie

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.

I also had trouble with Winchester shells in an Ithaca 37 20 ga. a few years ago. Occasionally you would pull the brass off the plastic. These were new shells and I think they were big box store heavy loads. I seem to remember Winchester was having troubles like that in all gages about 10 years ago. Lee.
