[KBurgoyne]

Im looking for some lad bullets for the 45/70 that seat out further that the standard 2.550 similar to the lyman 457124, http://www.midwayusa.com/product/63...caliber-458-459-diameter-385-grain-round-nose

I don't want to get into the lead casting business at the moment though so im looking for somewhere to just buy the bullets. Never you mind what for right now lets just say they can sit as far as 3.060.

Thanks in advance

Ive checked them out and several other places as well. There has to be someone out there who casts and sells Lyman bullets. I bet I could crimp a 350 or a 405 in one of the lube rings.

KBurgoyne,
You can crimp them anywhere! However! If you are feeding them single shot, you don't need to crimp, at all!
The issues are having enough lube, the right type of lube for the propellant and velocity and keeping the exposed lube clean during transportation.
For accuracy, and in a single shot rifle. I prefer the bullet to pre engrave the rifling into the first driving band, when the breech is closed. Much like a .22 RF match rifle! Bullet diameter is ideally a close match to the throat dimension. Commonly slightly larger than groove diameter! Adjusting the neck tension on the bullet (with sizing die and expander ball diameter) will eliminate any need for a crimp for single shot loading. If you are using Blackpowder? Set the powder compression height so the bullet is sitting directly on the compressed powder column. A wad is not necessary with sharp and square bullet bases and proper lubricant. Without further information, I can't get more specific that this!

OK, Different application.
The biggest concern are the chamber throat diameter in the cylinder. In a quality made "resolver", they are all the same diameters.
The bullet diameter should match that diameter. Crimp is absolutely necessary along with a tight grip on the bullet, adjusted by the expander ball diameter. Reduce the diameter of the expander ball or eliminate the expanding step. Commonly done when the sized case is withdrawn from the sizing die. This increases the tension of the case neck, on the bullet. It also makes it more difficult to seat the bullet. A slight bell in the mouth of the case aids in this operation. It also really works the brass. From a bell mouth to a crimp. Splitting of the necks can be expected, unless you anneal them regularly.
If you use flat nosed bullets, you will have more powder space if they are seated out. However, the overall length must never extend beyond the end of the chamber. OR! You will lock up the cylinder.
Expect really significant recoil! MOF possibly wrist damaging! John Taffin (an old time handgun expert) suffered from those injuries. He wrote about his crushed wrist bones when he was testing the .475 Linebaugh!
Have Fun!

IMHO, if ya want a big bore and ya have the Jingle, I would look at one of these. The cases are made from .45/70. The revolver is more traditional in shape and the bullet weight is similar. Very nice Resolver with some unique custom options.
I have a 7 1/2" M-83 Premier Grade with express sights and in .454 with a spare .45 LC cylinder. Course, the octagon option was not available 20 years ago! DANG, Its been that long???

Yeah they cost a little over double though, magnum research makes a great revolver. Nothing will compare to freedoms fit, finish, and outright quality, but MR is up there with their quality standards. Definitely over smith and ruger.

I figured if I had the freebore, might as well use up some of it. Lower pressure less stress on the forcing cone.

FYI a 525 grain hard cast in front of 52 grains 3031 seated at 3.000" makes a good plinking load. I was surprised by just how controllable it was even with the cheapo hard rubber factory grips which are already on the chopping block. No wrist stress at all, just a little sting from the hand punch, and I wasnt wearing gloves, and it was about 50 degrees. The thing weighs around 5.5 pounds with the scope, and gains another 5 to 9 ounces when fully loaded.

The thing is a tank. I compared it to the N frame smith I have. Double the meat between the cylinders, double the frame thickness, the inherent strength in a single action one piece frame, the inner locking lugs are between the chambers and are a machined piece of the cylinder, and the cutouts for the outer lock are also between the chambers where the N frame has them directly over. All of that and the cartridges fired in each are rated for the same max pressure.
