[QUOTE="Greyfox, post: 1703066, member: 10291"] Years ago I did a lot of work with the double express rifles. My go-to for the dangerous critters was a H&H 450 Nitro Express(500-450). Ammo was no longer available for the rifle. Fortunately I could neck down 470 cases to 458. I found the key to regulating the load to the rifle was to duplicate the original velocity and most importantly, shape/ogive of the original bullets, generally Kynock. After struggling with the usual contemporary 458 billets, I found that the Woodleigh 480gr bullets were an exact match for the original Kynocks and would regulate to the original spec. For powder I got best results with IMR3031(76gr) to generate the original velocity spec of 2150FPS. Because the cases are so long in order to accommodate the original Cordite used in the day, I would use 2gr of Kaypoc filler to keep the power against the primer. Modern powders take up less space. The 50 yard shots, 2 from each barrel matched the H&H spec of 1.5” for 4 shots at 50 yards to exact POA. This basic approach worked well with the 400 to 470 caliber express cartridges. I used this hand-loads to take this cat and my H&H at 22 paces Also, a slug(follow-up) that entered the front of his chest and was recovered from the hide under his hind quarter. Added comment: Some asked about the insert in the photo of the Lion. This photo is from William Buckley’s Book, “Big Game Hunting in Central Africa”. My rifle was originally purchased by Buckley in 1904, and is shown in the insert along with a lion he shot with it. I thought it ironic that I shot my lion in 1994, 90 years later with his rifle.
