Which swaged bullet for 45/70 long range?

[BulletBrain]

I'm looking in the midway catalog at the 480 Schmittzer and the 535 Postell.  Do you guys have a preferance? Or an even better suggestion.  I reload but I don't cast bullets in the apartment.  My gun is the 32" BC.  I also thought about loading a 500 grain Barnes X bullet in it but have held off for now.

The Lee 459-500-3R would be a good one, available from Montana, Bernie(dodd3) shoots em out to 800yds in his BC, they can easily be gas checked by hand if needed(FAQs).

This guy's books and articles are a wealth of info when it comes to long range shooting with a .45-70 :  http://www.mlventerprises.com/

With the twist rate of that BC the 480 schmittzer is a better choice, than the postell. The postell work alright in a 45-70 with an 18 twist, but the 45-70 lacks the steam to get keep it stable at long distance.  Another bullet that has been working real well in the 45-70s is the saeco 645.

Can you elaborate on that for the education of those who are just starting out with the BC?

Longer bullet needs a faster rate of twist to stablize, and especially at longer distances when the velocity drops off.  Crosswind can raise holy ned with some bullets when the distances start getting past 3-400 yds as well.
 Using heavy smokeless charges  or heavily compressed charges of 3f blackpowder in the 45-70 improoves the rate of success at distance with the postel, but there's a price in recoild to be paid for that.
You also get a rate of deminishing returns by going light (short) with the bullets , the original 1.1 inch length (405 +- grsx.) will shoot decent to 800 yds at times but most of the time starts to fall apart at 600.
 Think of it like a spinning top. When the top is spinning at it's highest rpms, it stays nice and steady, when it starts to slow down it starts to wander, and when it gets to slow it wobbles around a falls over. Bullets do the same thing.
