ChrisG>One last thing I will add. I wouldn't use Buffalo Bore's or Double Tap's, or any of those boutique manufacturers velocities as completely doable for the handloader... sometimes they are. But all too often, Buffalo Bore and other manufacturers have access to canister powders or powders not available to reloaders which can be tailored to specific characteristics of a specific cartridge. The powders available to us are designed to be as versatile as reasonable and that is why they are jack-of-all-trades, master-of-none. So you may be able to get close but don't be discouraged if you can't match Buffalo Bore's ballistics. Plus, as mention before in this thread. even at 1,700 fps these bullets will effectively take any game in North America and any plains game in Africa!
You also need to recognize the 45-70 has taken Cape Buffalo and Elephant by both Hunters and PH's who've used both commercial and their own reloads!
I am a physicist with much reloading experience. And, what I've learned is we all try to find the limits these technologies offer. But, I never get discouraged... I set goals and, within the limits of Safety and Reliability, always reach them.
As I develop these 450gr, 45-70, Cast and FMJ loads, I will report progress here at Africa Hunting. I own an Oehler 35P Proof Chronograph and will soon have a Pressure Trace Internal Ballistics System to capture Chamber Pressure.
However, the best advice I've received about my 450gr goals was from Crusty Deary Ol Coot on the Marlin Firearms Forum. Essentially, I raised the issue we all face at the start of a reloading project: with which powder type and charge do we START ("Starting Load") that is not too small as to be a (dangerous... at least via Parker Ackley Vol-1) reduced load?
CDOC's answer was great. Only we 45-70 Lever Action guys have a major resource at our disposal... all those published Starting Loads for the low power Trap Door Rifles are available across more than 10 bullet weights (including 450gr) and a wide range of powder types. The 50th Lyman Reloading Manual, 4th Lyman Cast Bullet Handbook and the 2nd Edition Lee Reloading Manual... ALL list these lower-power Trap Door Rifle Loads. The trick is to realize that a MAX Trap Door Rifle Load can also be the STARTING Load for the higher-power 45-70 Lever Action because COAL is identical for both 45-70 Trap Door and Lever Action cartridges. And, any FMJ load can be used to load a Cast bullet (of the same bullet weight), since an FMJ bullet is longer than the same weight Cast bullet!
Nuff said. Will keep Africa Hunting posted on progress to develop 45-70, 450gr Cast and FMJ loads for my 1895DRC rifle. I'll eventually try solid bullets after these Cast and FMJ load developments.
