This may sound crazy but here it goes. Looking for opinions before I start spending money on this project.
For a long time I have wanted to pick up one of the NEF tracker 12ga rifled slug guns. Finally picked up a rusty old beat up one this summer for 50 bucks with a broken stock, and got it cleaned up and shooting pretty good with factory slugs.
As far as I can tell doing research the gun has a 1/35" twist as does the savage 12ga guns. Most of the others have a 1/26" or a 1/28" twist. Way more then enough for a 1.25oz slug (around 600gn I believe)
Now here comes my thing. Doing some research on boolit leanth and what not I have come to think that the 1/35 twist would support a 1400gn WFN style boolit. Bore on my rifle measures at .717" with the groove .727".
Looking online all I can find are 2.5" brass cases but I already have a few 3" (gun has a three
Inch chamber) so I'm sure if I looked hard enough I could fine more. If not, the inside of a federal roll crimped fired plastic haul is .711" so once sized that should be tight enough to hold a boolit as it would go a ways inside of the haul. I would like to use brass as them it would be more like a standard center fire cartridge.
Thinking I will start out using black powder after I have the mould and reloading tools made. For 2 reasons 1 I like the big cloud of smoke 2 not worried about blowing my gun up as much because something goes wrong.
What do you guys think? Is it something worth trying or am I wasn't brain cells?
