I did not look at the Savage for that reason as it is the only available production muzzleloader that allows the use of smokeless powder and that comes with some additional problems anyway.
Are the Savages totally banned in Arizona, or just the use of smokeless powder? To be honest, even if I couldn't hunt with smokeless powder I'd still use my Savage exclusively as it is more than capable of shooting black powder subs. It's the finest ML rifle I've seen in terms of design and features as a result of being expressly designed to shoot smokeless powder. I own the 10ML-II BSS version with in stainless with the laminate stock and it's also a fine looking and feeling rifle. Very accurate too. Like I said, smokeless or not, I'd take the Savage over a Knight or T/C any day.
Forgive the digression.
