ORIGINAL: Underclocked
Those loads were not suggested by me. I am merely quoting words from Savage owners and owners of SMI barreled rifles. I've zero experience with smokeless in a muzzleloader and fully intend to keep it that way. But I do find the evolution and development of loads on the smokeless side worthy of attention.
"(UC's mysterious 3000 fps 200 grain projectile)" is neither mine nor a mystery but a load and performance suggested very seriously by a smokeless owner."
Forgiveme, UC. It was not, unfortunately, obvious from what you had written that it was some one else speculating about 3000 fps. I mistakenly took you to say that if the following were true, then 3000 fps was achievable. Evidently, you were quoting someone else.
". . . 67 grains of IMR 4198 with .75" to 1.3" accuracy. ..don't have a chronograph yet, but by the results had by others, that should put me around 2450-2500 fps with a 250 grain bullet."
I said something, because when I calculated the energy, the 200 grain projectile at 3000 fps had 500 ft-lbs more energy than a 250 grain projectile at 2500 fps. Now it seems that actual velocity of the 250 grain bullet is 2698 ave. or over 4000 ft-lbs. MY GOD!
Some time ago, I looked into the Savage. I noticed right off that there were no recommended loads over 46 grains. I figured that Savage only wants less than 46 grains in the muzzleloader in the event an obstruction occurs. The faster powders contain roughly the same energy as the slower powderson a per weight basis which means that in the event of an obstruction, charge of either powder of equal weight represent roughly an equal potential forreleased energy and thus roughly an equalrisk to operator of the weapon.But when one pumps up the weight of slower powders his risk increases in the event of an obstruction.
Frankly, I guess its none of my business what others are putting in their Savage. SoI guess if someone is willing to live with the risks they are taking when using their 10ML outside the manufacture'srecommendations, its none of my business. Where I take issue, is when that same person can't resist the urge of sharing hisactions with others, spreading the behavior around so to speak.
