Sorry couldn't help myself, but in case in other average shooters like myself are curious about lead conicals and their performance please read my original post.
Sorry but the opening line is total hogwash. Its like saying CVAs shoot Powervelts best. As if the twist and barrel are magically made to shoot them better than sabots. Even though the CVA barrel is no different in twist and number of lands than the vast majority of new inlines.
The biggest mistake people make shooting conicals is using too much powder and not trying different wads. Ive owned no less than 4 45s. Twists including 1-30, 1-28, 1-22 and 1-20. They all shot sabots, Powerbelts and conicals fine when you found the combo it liked. None of them were overly fussy. My 54 is a 1-28 and my last 50 is a 1-32. White rifle 45s were .451 which is in the ball park for many other brands too. I currently have 2 that are .450, 1 is almost .451 and the last is .452 on the lands. Funny part is they are all Knights but from different years and models but they are all Green Mountain barrels.
The vast majority of new 50cal inlines are 8 lands and a 1-28 twist. Lands from .500 to over .502. There are a few exceptions to this such as Pedersoli plus a couple Traditions/CVAs. Cramming a light for caliber conical in a modern inline with 100gr+ of modern subs is usually gunna yield crappy results. People have become so accustomed to that type of load behind a sabot or Powerbelt it never crossed their mind its too much powder. They got no idea a wool wad might work better then a veggie or poly wad. Let alone a 54cal wool wad might even give them better results in their 50cal.
User errors like this are because so many are just seasonal ML hunters wanting another chance to harvest a deer and those people typicaly use whatever the brain dead salesman at Cabelas tells them to shoot. Shooting conicals is not that much different than sabots. Find the size that fits your barrel best and the load it likes behind it. No brand has ever made a inline 45cal or 50cal that is somehow magically "made for sabots or Powerbelts".
