I read this review on Buckmasters site;
Two 50-grain pellets yielded shots above 1,800 fps using 240-grain saboted projectiles. Three 50-grain pellets achieved over 2,000 fps with a variety of 240- through 290-grain saboted projectiles.
White Hots are easy to load and leave behind little residue, which makes for easy cleaning. After more than 10 rounds, I swabbed my rifle bore spotlessly clean with three wet patches and one dry patch.
White Hots are intended for .50 caliber inline muzzleloaders using any 209 shotshell primer ignition system. A new portable hunt pack allows loads to be taken to the field packed in transparent tubes for easy access and minimal contamination.
I took two muzzleloaders on this hunt. Both were pre-sighted with two pellet charges of Triple 7 Magnum propellant. My Traditions Guide Gun, shooting 300-grain APB sabots, placed three rounds literally on top of each other from 50 yards away using two White Hot charges.
My Knight Excel clover-leafed three 435-grain White Power Star projectiles with the same charge. Shot to shot consistency of White Hots powder is simply superior.
The real appeal of IMR's White Hots is the excellent consistency from shot to shot that I witnessed from all the muzzleloaders we used. I don't remember any propellant producing such uniform groups from such a wide variety of rifles and projectiles.
The main thing that has me interested in them is that they are supose to be really clean burning, just a water wet patch between shots all that's needed and their consistant accuracy. Anyways, I'd love to hear if anyone has given them a try and how well they either liked or didn't like them.
