Dan....... I just sent my money to you for a 100 of those heavy 45-70 bullets. Going to use them in my 45-70 Buffalo Classic Handi Rifle. That should be a modern load Group 2 or 3 class, like Marlin Guide gun or Ruger single shot.
I need some loading data, like a starting load, recommended powder, and top pressure, max loads. Starting loads to work up to a max ..... given the weight I am not too concerned about speed!
Thanks for your past help,

Hey Dan........
I got those .458 45-70 heavy bullets 575 Gr today. Pretty little jewels in that great custom box! I almost hate to shoot them!
I will need a starting load and some velocity expectations, so I will know when to quit testing........Pleeeeeze!

One of my universal loads for heavy bullets in a 45-70 is 21gn 2400. I have only used this load with up to about 530gn bullets and get 1270 fps. This is my stand by load for my 1884 Trapdoor. I have not tried it with that big 585gn yet and if I do will drop to 20gn to start. Anything I shoot in a TD should also do well in your Buffalo Clasic as well as being safe. Safe TD loads are under 20,000 psi so also well within the pressure limits of your rifle.
I do use packing popcorn as a filler in my loads but likely is not needed but I would use magnum rifle primers without the filler.
Have fun!

I should have mentioned that in the future if you order again and your ordering a gas check type bullet but you will be shooting them at low pressure/velocity you can order them without the gas checks. They will rarely ever shoot worse than with the gas checks at low pressure and in 45 cal you save $6.00 per 100 bullets.
I also wanted to mention another stand by 45-70 load that I use for target shooting. You may not want to use it because it is a duplex load but I will share my load data if you want. It produces slightly higher velocity than the 2400 load but still low pressure and still in BP velocity range.
Its the load I used to shoot the Quigley match and I did very well with it.

2400 and lead are like two peas in a pod. They seem to get along just fine in rifle barrels.

A very nice aspect of the 21gn 2400 in the Trapdoor is that the 1270 fps regulates to the original Buffington sights. Any ammo submitted for military acceptance had to have a velocity bracket of from 1270 to 1330 fps fired from the infantry rifle. Ammo with velocities outside this bracket was rejected. The velocity requirement was to insure sight regulation.
A 500-520gn round nose bullet within this velocity bracket will regulate quite nicely to the original sights. With the sight down in the battle position this load will shoot about 24" high at 100 yards. There is no 100 yard setting on this sight. This is why you often find Trapdoor rifles with a non original front sight blade that is taller than the original so it can zero at 100 yards.
I made some tall front sight blades but have gone back to original front sight blades because I pretty much only use my TD for long range shooting and having sights that regulate very closely for long range shooting is better than having a 100 yard zero.
I have noticed that with our version of the arsenal 500gn RN design ours being about 525gn the slight increase in weight over the arsenal 500gn RN gives our bullet a slightly higher BC. That slightly higher BC is not noticeable to about 600 yards but beyond that it begins to shoot a wee bit high of the sight settings. At longer ranges like 1000 yards the slightly higher BC makes quite a difference and to hit at 1000 yards requires a sight setting of from 850 to 900 yards depending on the atmospheric conditions. I do very much enjoy taking the old Trapdoor out and ringing a 4'x4' steel gong at 1000 yards or shooting a bucket like Mathieu Quigley at 500 to 600 yards. Simple pleasures!

Daniel, now that I see you talking like this, maybe I'll save my $$$, & just take old 1884 back to Forsyth again this year, but only use your 525 gn. bullets instead of the 405's.

If you dont already have a copy of Spence Wolf's book " Loading ammo for the Original Trapdoor Springfield 45-70" you should get a copy. Anyone that has a trapdoor 45-70 should have this book. In his book he explains the use of all the different type sights used on trapdoors and the loads that work with them.
Mr. Wolf has been departed quite some time now but I believe his wife still has the book available. This book has so much useful information on the trapdoor that even though I have read through it several times I have still not absorbed it all and still have to refer back to the book on occasion.
If you want to master your Trapdoor get this book!
