This magnum, extruded powder was created specifically for extremely big overbored cartridges like as the 7mm Remington Ultra Magnum, 300 Remington Ultra Magnum, 30-378 Weatherby Magnum, and others. When compared to other standard magnum powders, Retumbo adds 40-100 fps additional velocity to these cartridges.

Because Hodgdon Retumbo is an extreme powder, it is relatively temperature insensitive. It’s ideal for usage in overbore cartridges. On the downside, Hodgdon’s Retumbo isn’t ideal for softer, more efficient cartridges like the 6.5 Creedmoor or the 308 Winchester.

Many shooters choose Hodgdon H4895, Varget smokeless powder, and Accurate 4350 powder. They’re excellent selections for a wide range of bullets and cartridges. IMR 4350 smokeless powder is another popular contender for finest all-around smokeless rifle powder.

Because it produced almost little smoke and was three times more powerful than black powder, Vieille’s powder altered the effectiveness of small firearms. Higher muzzle velocity meant a flatter trajectory, less wind drift, and less bullet drop, allowing for 1,000 m (1,094 yard) shots.
