Ok, so I have no real need for a new barrel as I have a wide range covered already, to include .223, 30-30, 309 JDJ, 45/410, and 45/70. All these are longer barrels, 12-16 inches.
I am specifically looking for something designed for the 10” barrel and have no need for it that the above-mentioned will not cover. I would like to be able to take up to deer size game if it strikes me to do so, but mainly want it for pleasure (which in my book is shooting, no matter for what reason or even for no reason). So maybe on day I’ll be shooting paper, silhouettes, or any type of target. The next maybe crows, groundhogs, or coyotes and maybe I might even get the idea one day to work up a load for deer.
To sum it up, it must be a caliber that’s design is optimum for the 10” barrel (Not just a good round that also works in the 10” as most will), and have a lot of options for loading. The more options the better as I have no real use in mind for it, but after experimenting hope to come up with many.
