Mike,
One of the typical lines from users of modern inline ML rifles is that they do not think the traditional ML rifles can do the job.
This line of reasoning by inline ML hunters demonstrates their sheer laziness in not wanting to learn how to shoot a traditional muzzle-loading rifle as the traditional guns have been getting the job done for hundreds of years.
The shooters of modern inlines are the kind of hunter where a 20rd box of cartridges for their modern .30 caliber deer rifle will last them a decade. It is to this clientelle that the modern inline ML rifles were invented by manufacturers.
The slobs wanted in on the primitive firearms season and thus manufacturers created the inline ML rifles. This inline ML fad will only last until the slobs can find a legal loophole that will let them bring their modern cartridge rifles into the primitive firearms season.
