RE: Need advice on amuzzleloader.
First off you better check your regs to find out if an inline can be used in ML season or just regular firearm season. Many inlines to choose from; I would suggest 209 ignition foremost, then you pick the brand based on feel and budget. I shoot a rem 700mls and have no issues. My groups at 100 yards are an 1", I can shoot out to 200 but max my yardage at 150. While most Blackpowder inlines will shoot past 150 I think this a reasonable limit to expect. I have taken 8 animals with the 700 and only one was around 150 yards, the rest have come around 100 or less. If your using iron sights figure more around 100 yards.
Now if I was buying new today I would pick a Savage MLSII, this the ML that you can use smokeless and BP or subs powder in. My hunting partner just picked one up and they are shooter's!!! Needless to say I am/was very impressed with the savage and the price is a lot less than one might expect.
I agree try posting in the BP section, lots of knowledgeable shooter available.
Good luck!
