In the Model 700 ML (muzzleloader) we have found in our testing that FFg blackpowder, Pyrodex RS and Pyrodex Select provided the best results. The new Pyrodex pellets can also be used--up to 150-gr. maximum. However, we have found our best results came with 90 to 120 grains of the granular blackpowder or equivalent. For complete load data, please refer to the Model 700 ML owner's manual.
This data was compiled from testing done by Remington® Arms using both .50 and .54 caliber Remington projectiles in the Model 700™ ML rifle. The Model 700 ML barrels are rifled with 1 in 28" twist in both .50 and .54 caliber. All testing was done with 2F or FFg black powder.
WARNING: NEVER EXCEED THE MAXIMUM CHARGE WEIGHT LISTED FOR THE PROJECTILE YOU ARE USING. NEVER SUBSTITUTE ANY QUANTITY OF ALTERNATE POWDER TYPE OR GRANULATION. Failing to adhere to these maximum charge weights or substituting any powder type or granulation could result in serious personal injury or death to the shooter or bystanders and damage to the firearm.
The charge weights listed are the nominal range and maximum charge weights for the given projectile. The nominal suggested range of charge weight produces the best combination of accuracy and velocity. It is done by starting at the lower charge weight listed in the nominal range and increasing in 5 grain increments until an optimum load is achieved. An optimum load is one which produces the best accuracy.
WARNING: Do not exceed this charge weight. To do so may result in serious personal injury or death to the shooter or bystanders and damage to the firearm.
