If you are refering to a load your own load, I agree with the above post, a 405gr bullet in the 1300fps range is plenty of medicine. The 45-70 has whacked them and they stayed whacked with that load for a good long time. In the 1895 they are not going to beat you up and are generally given to good accuracy.
I have found good results with Laser Cast 405 flatnose, .459 over between 29.5 and 31.5 grains of AA-5744. Winchester, Remington, or Starline brass. Standard large rifle primer. Crimped safely for
My guide gun likes anything cast close to .459. This hard cast bullet can be pushed up to 1500 fps without a gascheck. 1150fps to 1300fps is potent whitetail fodder, easy on the old bones and I can get better than MOA of small paper plate at 100 yards with XS ghost site...bob
I'm sorta in the same boat. Heres what I've got goin on.
My dad bought some Laser-cast .45/70 350 gr pre lubed boolits at Cabelas a couple of weeks ago. Now guess who he wants to load em up? I've looked fer data but its hard to find. Found one load listed fer this bullet on handload.com. I've emailed the Co. that makes them but I'm always lookin fer more info afore I start. He is shootin a Marlin 1985 SS but fer him I'd like to start in the trapdoor range and move up from there to see where he can handle it. Also how much different is it to load cast instead of jacketed? Is there extra steps or precautions I need to be aware of? Usin RCBS loadin dies and have a LEE FCD to go with it.
Now I haven't hunted NY State whitetails in many years, so I really do not think that you would need a 405 grain bullet.
My favorite Trapdoor level load is Remington 300 grain HP, WLR primer, and 24 to 25 grains (depending on which rifle the rounds are loaded for) of SR4759. This load and the right light, my Browning 1886 will print 5 into about 1 1/4" group at 100 yards. My Lone Star Rolling Block will do about the same.
I had the same questions a few months ago. I have the same 350 grain lead bullets that I picked up and Cabelas. I was looking for something that would be pleasant to shoot, be accurate and also take down a deer. I had several people tell me 14 grains of unique under the 350 grain lead bullet would do the trick. I can tell you that this load is accurate and not hard on the shoulder. As far as it taking down a deer, I haven't had the chance to try that part yet.
If you don't mind the clean up, I've had outstanding results with the 405 grain lee 459 hollow base (40:1) over 53 grains of 3F goex. I've clocked it at 1250 fps out of my trapdoor and you'll most likely see around 1100 out of a 22 inch barrel. Mild recoil, limited smoke and the bullet mushrooms like a champ. It knocked the slats out from under a small whitetail that mistakenly crossed my path.
Due to the soft lead you can keep your loads to the trapdoor loads in the accurate manual for AA5744 and you'll see a bit more velocity without leading or clean up.
I just perfer the smell of using a cartridge with what it was designed to use.
That is why some want a lighter load...nit that they're weines but the heavy loads it is possible that it can break somethin or if its pushin agianst a metal bar you feel it more. ALOT more. But you still love shootin it so ya want a load that'll humanly kill what yer after and still be able to clean it.
