I' ve used about every different shot size between 00 and 4 for yotes, and depending on the situation, I' ve never been let down by any of them...i.e. I only use #4 up close, only 00 when they' re at 40yrds or slugs at or past 40, etc., good hunt planning yields good hunts.

I' m guessing your turkey shells are gonna be #2' s, so they' d be really good for yotes, especially since they are " highpower" or " high velocity" which basically only gets you to pay $10 for 10 rounds instead of 25rounds and serves no other practical purpose, but it does add JUST A LITTLE extra oomph. I' d say as long as they pattern well, say 60-70% of your shot hitting a coyote torso sized target at whatever range, you' d do well enough out to 45-55yrds, but that' s just me, I feel that 75yrds mentioned above is extremely generous, maybe a 60yrd shot would be feasable, but out to 75 is pushing it.

In rifled shotguns aka slug guns/barrels, you NORMALLY won' t shoot large sized shot very well, smaller shot will group pretty tight normally, but the bigger shot fight eachother as they leave the barrel, so they don' t group worth much usually. If it does pattern well for you, then good for you, and good luck with it. You don' t have to worry about damaging your rifling because a) shot lead is much softer than barrel steel, so even if they hit it they wouldn' t do much damage, and b) your shot' s gettin pushed down the barrel in a plastic shotcup, so it ain' t gonna touch the barrel anyway.
