Skout .25 Barrels, And Slug Selection.

In a general sense, I'm trying to get you folks to help me put together a shopping list of sorts. I recently ordered a Skout Evo .25 cal, with the 34.4" barrel. At the heart of the matter is my question as to the optimal pellet size. As in diameter. There are many options available, and I'm hoping with you folks input I can winnow down the choices, and avoid buying slugs that are too large in diameter to feed properly into the rifle. I'm assuming that the Evo, and the Epochs in .25 share the same bore diameter, though I could be wrong. For all I know the barrel could differ just between the 25" barrel, and the 34.4". Again, I really don't know. So just guessing that there's commonality in bore sizes between the two models I was hoping to get some insight before placing an ammo order for testing. Any input is greatly appreciated.

TIA
 
Start with the CORBIN slugs built for the guns and sold by SKOUT.
They will be the correct size ... play from there.
Like @Motorhead said, "slugs built for the guns". I doubt 2 tins will be enough. I've shot lots of these slugs.
That high BC .2475" slug was made for the Evo .25 platform.
I thought the Evo guns were setup for this slug out of the box.
Might be good to call Skout.
