Frequently Asked Questions

What are the key specifications for loading ammunition for an Alexander Henry Double Rifle in .450 3 1/4" Black Powder Express?

For the Alexander Henry Double Rifle in .450 3 1/4" Black Powder Express, use 300-grain cast lead bullets (.458 diameter), 120 grains of Goex 2FG black powder, Federal Large Magnum Rifle primers, and Hornady brass, with a 1 in 38 inches twist rate and Henry rifling.

What is the recommended bullet lubrication technique for black powder rifle cartridges?

The 'pan lubing' technique with SPG beeswax-based lubricant is recommended. This method ensures the grease grooves are fully packed, which helps reduce barrel leading and keeps black powder fouling soft for better accuracy and easier cleaning.

How is case preparation performed for .450 3 1/4" Black Powder Express ammunition?

Case preparation involves bellying the case mouths using an RCBS RC IV press to prevent damage to the bullet during seating. Federal Large Magnum Rifle primers are then seated for reliable ignition of the black powder charge.

What is the significance of Henry rifling in an Alexander Henry Double Rifle?

Henry rifling, characterized by seven flat sides within the barrel, is a specific rifling style developed by Alexander Henry. It is designed to work effectively with the slower twist rates common in cartridges like the .450 3 1/4" Black Powder Express.
