Resizing Magtech .410 brass

[Lee-fan]

I have been loading the Magtech brass .410 cases with great results in my contender. However, after firing in it, the cases will no longer fit any of my other .410's. Does anybody have experience resizing these? What die and shell-holder might I need? Thanks!

.30-40 Krag or .303 Britt shell holders should work ( some are a number 5 ) If Magtech uses that size rim?
I've had good luck with a .41 Magnum sizing die that is straight through. ( no theads ) You may be able to use a straight through Bren 10 sizing die as well.
I use a LEE universal de-capping die.

If you want to resize it to factory specs buy the proper dies from CH4D.

Funny I would say don't sweat sizing them, reload them and shoot them again in the same gun they were shot the first time.
Essentially fireformed.

Excellent,thanks! Will check on the shell holders, also just checked the ch4d dies, I think thats the ticket. I have 3 contender barrels we use, and 4 long guns, and only 2 will swap back and forth. It's just too much to keep the brass seperated.

Just checked out C&H 410 brass shotshell sizing and crimping dies! In case anyone wants to look at them here is the current link.

I use a lee 45acp Factory crimp die with the guts removed so I'm just using the lower portion of the die to size the case

I use 45 acp sizer dies. I have several but only two work. One is an old RCBS sizers die that uses the #2 die to deprime. The other is a Dillon die, both have a threaded hole in the top that allows the case to come out the top without hitting anything. A couple other 45 acp dies have too small of hole in the top to allow the 410 case to go all the way in.
