*EDIT*
I did just some '
research' on this. Seems it's been asked b4, lots of Opinions & Forum threads on it. & Examples of many doing it,& many saying Don't do it etc. The Usual banter. Seems to vary with the person & their experience/knowledge. From people using cheap Target loads to shoot Dimes/Quarters, Steel bars you name it lol - to making viable Slug & Buck rounds out of them. Interesting Topic to read up/research on.

'Theoretical' Question time. Obvi. I'm very
Novice in the 'Reloading' game, & Apologies Up Front if this is just stupid

Just started looking into reloading 12 Gauge. After looking at each shogun component needed to buy, for reloading, then buying them all separately, Including hard to find Primers, powder etc. & then seeing this Box of 250 Target loads I got for around $100 sitting here, is it possible, to use those already loaded factory rounds, & just replace the #7.5/8 bird shot, with '00' or 000 Buck or Slugs
?
It would be a lighter load, {like those Mini Shells, which are still $1+ per round} but would it work?
Could the velocity be increased, by adding a little of the same powder from some of the same shells, after figuring out the proper weight/ratio etc. of what's in there, to accommodate a Slug or buck load?
Theoretically
'could' work, but, probably dumb, esp if inexperienced...? Ive seen Dumber things loaded in shells on Demolition Ranch lol
.40cents per target load + cost of shot, or slug vs. over $1 for factory slug or buck.
With Components sky high prices & hard to find these days. Is it still just a Dumb thought? IF it will work lol ? Anyone Done this ?
