Okay, here is my question. I shoot in my .54 Pedersoli Jager, Lee 380 grain bullets. Before I burn more powder, I was reading the article in the current MUZZLE BLASTS about using less powder. I got to thinking, as I am always seeming to use different powder charges (and forgetting what I am using from year to year more than ever now - and yes, even forgetting to bring something to write down the loads in). What would be a low charge for this grain of bullet for just target shooting as opposed to hunting (which is what I primarily use this gun for with about 80 grains of 2F)
The Doc seeks answers from the community for his further education now.
Barrels with faster twist rifling produce better accuracy results with low powder charges than barrels with slow twist rifling.
I discovered this about 50 years ago when I was shopping for a much lighter big bore hunting rifle to pack in the mountains to replace the Hawken I built & bought my first original .70 cal. Jaeger. Found it would produce clover leaf 50 yd groups with just 50-60gr & was a long range Elk dropper with 80gr.
NOTE; The majority of factory production built muzzleloading rifles I've owned & examined have had shallow depth rifling in the .004-.007 depth range. Rifles with shallower depth rifling & fast twist rifling tend to require a much a tighter patched round ball combo when shooting heavy loads in order to prevent poor accuracy due to shredded patches & blow by.
The vast majority of vintage European & English muzzleloading round ball firearms I have collected & competed with over the years have had faster twist & deeper rifling in the range of one-turn in length of a 24" to 32" long barrel & have rifling depth in the .010-.014 range.
It's been my experience that deeper rifling depth with fast twist rifling provides a much better grip on patched round ball loads when using heavy charges & superb accuracy.
Early English & European gunmakers set world standards for quality & accuracy, thankfully many came to our American colonies for freedom & to build guns for our 1st revolution.
Have been a faster twist muzzleloading competitor fan every since
