That's really good. I had to look it up that Traditions Deerhunter has a 24in barrel.
Perhaps barrel length doesn't really matter under 100m as can be concluded from replies to this thread.
I wonder if there is anyone that shoots a round ball to 100m with good accuracy using a 24in barrel. If not, it may be that accurate loads for short barrels (24in) don't have enough velocity to remain accurate at 100m?
28in is in my book a "medium length" barrel. I shot my 50 cal to 100m with good results and I haven't even developed a best load for it yet
Pistols in my opinion should be excluded from the comparison. I shouldn't have mentioned them in the beginning. I think so because of much faster twist rates allowing for good accuracy with slower speeds.
I have also recently found a good load for my 11in Pedersoli howdah 58. I could only take 4 shots at the time, but all went into the 10 ring at around 30m(hands resting on a sand bag) . It was 50 grains of 3f, a 575 ball from a Lee mold cast from pure lead and a patch that compresses to 10 thou.
I also feel my Remington cap and ball revolver with 7in barrel is definitely much more accurate than me.
Barrel length does not determine accuracy potential. Modern bench rest guys use short fat barrels. I have "unlimited" ML match pistols that cut one hole at 25 yards when shot off a bench. On the other hand I had had 36" ML rifle barrel that shot no better than 3" at 50 yards with any load off the bench. It had very deep, narrow, round bottom grooves. In that case gas leaked past the patch in the grooves. Certain factors are common to accurate barrels, smooth finish, consistent twist (or gain), consistent bore size (or choked), fairly straight, a good crown, and reasonable rifling dimensions.
This "reasonable rifling dimensions" is a very interesting variable. I read in few places rifling should be deep for patched round ball and shallow for conicals. However, my two most accurate round ball rifles both have what feels like very shallow rifling. I haven't measured it, but it feels like 4 thou. Perhaps with long barrels and slow twists one can get away with shallow rifling for round ball, while in shorter barrels (specially with the "universal" twist) only deep rifling will provide enough hold on the ball.
With your 36in ML with very deep rifling did you find any evidence of patch burn through or ripping? I wonder if gas blowby always rips a patch or can one have blowby with perfect patches?
