.608" rim dia, .506" at base of case, .070" rim thickness, .480" neck dia. .45-100 case dia at base is given as .505" from "The Illustrated Reference of Cartridge Dimensions" by Wolfe. | |||

The .45-90 has: rim = .597", base = .501", neck = .477" and is 2.40" long. I don't think that a marlin will allow that length, but a winchester 1886 will. It would be a simple rebore of the chamber. As for the .45-100, which one. There are the .45-100 Remington, .45-100 Ballard and .45-90 Sharps. The Remington and Ballard are too long, even in a Winchester 86. the Sharps is about a twin to the .45-90 Winchester. This info is from Cartridges of the World. | |||

What I was thinking about was a cartridge with the same demensions as the .45/70 only a little longer. I don't mind paying for the action work, but was hoping the barrel could just be rechambered. I'm familiar with the .457 wwg, but want to know of any other options. | ||

It's possible to get very little extra length out of the marlin. Maybe 1/10 inch. Cases based on the same case were likely to be called by different designations according to the load around which the rifle was built or the load as provided by the factory. So you will have 45-100s that will vary between 2.6 and 2 7/8 in length depending on the bullet weight. I believe the 45-100-550 was based on the 2 7/8 case. There are others who would know for sure. I think most rifles chambered for this case were marked 45x27/8. By the way , in a strong action and loaded heavy this about halfway between a 450 Watts and a 460 Wby. | |||

Bill and Wild Bill, the Sharps .45-90 is 2.4" version of the .45-70 (a 2.1" case). The .45-100 is the 2.6" case, and the .45-110 is a 2 7/8" case. There is also a 3.25" version that was never made or chambered by Sharps but is often called the .45-120 Sharps. Whether they would work in a Marlin, I have no idea. The 86 Win came in .45-90 but an express version (light bullets), as well as a .50-110 express. I use a .45-100 for all my big game hunting. But it's a Sharps, not a repeater. With 550 gr bullets, recoil is fairly brutal in a 10.6# rifle. In a lever action, I think it would be merciless. Brent | |||

Brent, I shoot a 45-110 in a Sharps, I�m curios if you are using black powder or smokeless? If you�re using smokeless, would you mind sharing your load data? At this point I�m only using Pyrodex loads in my Shiloh Sharps rifle. Monty | ||

Smokeless? What's that?  Nope, I'm using only black powder. I shot pyrodex in it once, and that was the end of that. Mine is also a Shiloh. Smokeless in these large case guns can cause detonations in light loads in large cases. I don't know much about smokeless and such, so this is all second hand. If you are going to shoot a .45-110, it seems that you would want to shoot bp with it. Otherwise, what's the point of the cartridge. Check out: http://www.iastate.edu/~codi/PPB/PPB.html if you want to look into traditional loading for your rifle. Brent | |||

Hey Brent, Thanks for your response, and I agree with you. I was curios about a smokeless load, as I have read about the same problems you mentioned. I love my Quigley rifle, and expect delivery of a 45-110 Montana roughrider late next month. Quick question, what brand and type of black powder works best for you in your Sharps? Monty | ||

Hi I modifyed my 1895 Marlin to take 5mm longer rounds. It worked just as well as the gun worket unmodifyed. I honestly dont think you want moore powder space, at least not for smokless. I am thinking of the recoil, I got 2150fps with a 405gr Remington FP bullet, it kicks a lot worce than my 470NE double. So in my opinion the limitation is reached in the recoil department at this level. The stock is not designed for "african rifle" levels of recoil. FYI a had a Uncle Mike 1" recoil pad on the gun.

When Bill Ruger introduced the 45-70 in the #3 and #1 he chambered it his way. Enough freebore to seat the 500gr Hornady soft point out to 2.94 inches. It doesn't make much sense to chamber for some off the wall cartridge when a 45-70 case will do more in the light rifles then civilized people care to shoot. Yes I load to the max and in a 6#carbine with a Pachmayr Decelerator no one cares to try it. No flinching either. You can send those 500grains to 1850+fps as well. It is where you can seat the bullet, not how long the case is. Accuracy? in the .3 any time you care with a 3X scope. ------------------ | ||
