While the rifle shown here, the Pedersoli .50 caliber No. 209 primer ignition in-line Rolling Block Muzzleloader, may have a very mid to late 1800's look to it, this rifle is actually somewhat advanced over the vast majority of other .50 caliber in-line rifle models on the market right now. And, that would be due to the fact that the rifling twist of this rifle's bore is a snappy 1-in-24 twist ... while every other production run in-line .50 caliber rifle comes with a 1-in-28 rifling twist.
So ... What Makes The 1-in-24 Twist So Advanced?
At this point, let's just say that it has long been my contention that we've "outgrown" the 1-in-28 rifling twist. William "Tony" Knight and I came up with that twist back when both the "ultra modern" in-line rifles and saboted bullet concepts were just getting off the ground, during the mid to late 1980's. Ever since, the 1-in-28 twist has become the in-line rifle "Industry Standard" - a standard that was entirely based on stabilizing fairly short .44 and .45 caliber handgun bullets ... using a plastic sabot ... out of a .50 caliber bore. Since those days ... the bullets favored by modern muzzleloading hunters have changed ... and so have powders, now much more energetic than the black powder and Pyrodex loads of the 1980's and 1990's. What hasn't changed all that much, other than the switch to No. 209 primer ignition, have been the rifles - which are still being produced with the 30-year-old 1-in-28 twist.Continue reading the article at namlhunt.com
