Things get a bit iffy as you approach 1in long figuring only 1300fps but .9" is no problem according to the calculators. One of the guys here used to shoot a 400gr "ish and it shot really well in his 1-30 but that was all 100 yards or less.
GM54-120, I fully agree with the 400ish Grain Weight in the 30 twist, But not the length. The .444-400 BACO bullet above is 1.090 in length and does absolutely awesome out of my 1:30 twist from 50 to 500 yards, I can’t comment beyond 500 yards as I’ve not been beyond that with a Muzzleloader yet. I take the bullet length calculation stuff with a fine grain of salt, VERY fine in these old Muzzleloaders traveling 1200-1500 FPS (The latter on a good day with a tail wind) I was told way back on another forum that i needed some gigantic weight/length bullet for my 1:28 twist 50 Cal LRH, My Lyman Plains bullet is the shortest bullet i own for .50 and .54 Cal at .85 and it shoots right with, and better in many cases than my other bullets, traveling nearly 1500 FPS From my .50 Cal. I have not shot them past 200 yards, maybe accuracy goes south beyond that? I bought some BACO .492-550 Grain bullets which were long and supposed to be well suited for my 28 twist (can’t remember the length now? I melted them down) My 1:28 Twist .50 LRH Shot them worse than any bullet I've tried in it to date.
I strongly believe in bullet length/twist ratio with Center fire type velocities of 2700 FPS and well above. But I’m not buying it in these old Sidelock Muzzleloaders that are in the 1200-1400 FPS range, and under 300 yards. I do believe it comes in to play at really long range of 500 plus yards, But truth is I don’t have experience there YET so I can’t intelligently comment, I am placing my Soule sight order this morning, So I’m about to learn. I plan to try various weight/length bullets out to 800 yards
The best calculator in my hands on experience is to shoot different bullets from your rifle and see what works best in it

are they at least threaded for breechplugs? or are they just barrel blanks?

GM54-120 said:A certain number of rpms is required to stabilize a bullet. You can shoot them faster or twist them faster in the barrel. Once it leaves the barrel, fps and rpms start to go down. Its quite possible a bullet that clover leafs at 50yards is all over the target at 150yards. Conicals can only handle "X" amount of velocity in the barrel before leading becomes a problem. You can only twist them so fast until they start "stripping" in the lands.
Shoot them too fast and spin them too fast...you will have a ton of barrel scrubbing in store for you.
Like anything else its a balancing act. How fast do you want to shoot them and how heavy do you want to go? Ed's little 350gr "Gould" bullet is right at home in a 1-30 and a joy to shoot as well but its not going to win any long range awards. Its also not going to stand upto really high impact speeds very well either.
GM54-120 said:That 389gr you made looks really good to me especially if you want to shoot it in a 1-30 at 1300-1400fps. My old 1-30 Elite and 1-28 Accura would shoot a 360gr insanely well with slightly hotter than normal loads.
