Considering that smokeless powder is illegal in both of the states mentioned in this post, these observations are no more pertinent than me talking about the performance of my .300 Win mag. Really, what I'm reading here is that even the most extreme examples of ML performance, which you are both citing, barely meet the generally-agreed-upon 1000 ft lbs *minimum* to kill deer at 500 yards, and are well below what is necessary for elk. To start another dumpster fire, my .223 has more kinetic energy at close hunting distances than the 500 yard example bradb gives above.
Just your periodic reminder that it may not be a good idea to advertise the maximum capabilities of world class shooters to a guy who is exploring the idea of purchasing his a LR muzzleloader, and that blackpowder ballistics are less impressive at truly long range than they are on the internet.
Again, respectfully disagree with your assumption of the energy to harvest at 500yds.
Because I'm disagreeing, I'll provide information why.
1st...…… Just because smokeless propellant isn't legal, does not mean that a top BP substitute, such as BH209 can't be used in the same custom rifle. Actually, 'the best custom rifles make the best BH209 rifles'.
Here's the ballistics of a
CUSTOM 45cal rifle using BH209 and
NOT SMOKELESS PROPELLANT.
Its not "real blackpowder" but it is blackpowder substitute, a very good one also.
I did not change or eliminate the wind values which is why they show on the chart. But for the record the wind is based on a 10mph wind at 90° to the bore.
1,800fpe at 500yds will work on the game you mention.
Also for the record.......... just because the rifle is very capable with FPE at 500yds, most shooters should avoid attempting these long range hunting shots. It takes a TON of practice, a great range finder, and a hunter who understands the wind and has fired enough rounds to be 100% confident with their shot placement.
