My Kodiak had roughly .008" deep rifling. Impossible to "strip" with the loads that actually regulated.
The fellow I bought the rifle from had tried a number of different slugs with different powder charges and couldn't get holes within a foot at 50yards. THAT is why they have 2 sights, one for each barrel. LOL What a farce!
I was just lucky mine would regulated with both 100gr. 2F and 110gr. 2F. As this was 20gr. of powder less than I wanted to use for moose and big bears, I sold it.
Fine deer rifle, though.
If all I did was shoot from a stand, even the 85gr. 2f charge might have been enough.

Where I live and hunt, you might get a shot closer than 25 yards, or your only chance that fall might come at 200yards.
I did not feel enough confidence in the rifle.

Slugs only work well, if the gun will shoot them well enough(and they don't move off the powder).
