.54 long(er) range load
I'm working on a long range load for 150yds+ for my .54 1:48 twist but I don't have access to a chronograph - I just wondered if this load would stay supersonic at 100yds.
35'' barrel, powder swiss 3FG, 70 grain, 380 grain maxi ball. (3 grooves) Any rough guesses? |

.54 long(er) range load
Have a question. Why 3FFF? As common practice is the use of 2FF in a 54. I'm not saying it can't be done. But again it is hard to estimate speed on an unusual recipe request. I do wish you luck in your search and with your Longer Range Load.

The author Sam Fadala wrote about using 3F for hunting large African game with big bore black powder rifles along with the founder of Navy Arms Val Forgett. Fadala touted about loading 3F in just about every caliber muzzle loader, especially for hunting.

I'm only using what works for me, I know that most people say that anything larger than .45 needs 2F powder - I've found out that the higher pressure 3F works better with conicals that rely on expansion to engage the rifling. In all of my rifles 3 DF works better, .58 springfield with minie-ball, Hawken with maxi-ball etc. (pure soft lead conicals that can be scratched with the fingernail), it even burns much cleaner, I get noticeably worse results with slower burning powders like 2F.
Though I wouldn't use 3F with patch & ball. I also converted a fellow shooter to 3F and it improved the accuracy of his rifle. Quote:

Using the 15 ft-lb of kinetic energy per grain of black powder rule of thumb, I calculate about 1150 fps at the muzzle.
I had to go to 90 grains of powder in a .45 cal rifle using 220 grain Maxi balls before the rifle would group. Only 70 grains is an awfully light load for a .54. The ballistic coefficient for Maxi balls is better than for round balls, but only barely. To still be supersonic at 150 yards is going to take a real butt stomper of a load. |

check presures
Sam Fedala's BP loading manual: Nowhere does it give a load of 3F for elongated 54cal bullets. The 3f loads are for balls, but 60grs of 3f will produce more pressure than 60grs of 2F. as long as the safe pressure for the gun is not exceeded all should be well.

you really want to shoot this gun at longer ranges???
change the sights to a rear tang peep,,,let the heavy bullet work its magic,,it will get the job done if you can get it on target that bullet will probably go through an elk at 250yrds running along at the 900 to 1000 fps what is a 54 conical weigh in at 425-480gr i shot a buffalo at 325yrd with my 45-70,, bullet was 480gr soft lead,,leaving the muzzle at 1150fps,,i retrieved the bullet under the off side skin,,had she been 50 yrds closer i have no doubt it would have passed through her,,,i have never retrieved a bullet from an elk or deer its the bullet weight,,,you just have to get it on target change the sights my .02 ocharry
