44-70 Maynard

Print Post  
  Does anyone on the forum have any experience or information on the 44-70 Maynard cartridge and rifles chambered for it. COTW gives a little information on the cartridge itself and I see that Buffalo Arms has brass and dies. I am looking at a Shiloh Sharps that has been re-barreled by John King in this chambering and was curious if anyone out there has had any experience with loading or shooting a rifle in this chambering. From what I have gathered thus far it is a 44 caliber based on the 45-90 case trimmed to 2.200 length and then run into the sizing die to taper it to the 44 caliber. Sounds interesting, and the 44 calibers are ones that I have no experience with. Any input would be appreciated.

Hi S.S. Sam --

It has been awhile ( 4 1/2 years) since you posted your interest in the 44 - 70 Maynard cartridge.

I would like to know if you ever pursued your 44-70 Maynard project beyond your above inquire.

The 45-70 Gov't case is shorter in length as compared to the 44-70 Maynard, however, there is the possibility to substitute the 45-70 Gov't and was interested in whether or not you have gained any experience in doing so which you would care to share.

Dr, I have no personal experience with the 44-70 but have heard good things about it. That it will do everything that a 44-77 will without the problems associated with bottle neck cases. Rumor has it that it is good out to 1000 yards with the right bullet.

Timely post. Just ordered a 35" heavy Krieger 44cal barrel with a 17" twist and plan to chamber it in 44-70 Maynard for long-range work. Likely build a long-range Hepburn with it, but may do an 1874 or 1885. Undecided, but have seven months to make up my mind. As mentioned, the 2.10" long 45-70 case would be short, as the nominal length on the 44-70 is 2.21". A gunsmith/friend has a line on a 44-70 reamer, which would be nice. Have the chamber drawing for same.

I expect that John King's version uses standard .45=70 length cases...  I know he shoots one personally.

Other than saving a few $$ on brass, I do not see any reason to bother with a 44cal based on the 45-70 cases. Am likely going to have my chamber cut to 2.25" or even 2.30" to gain case capacity. Will cut down 45-90 cases for same. Using the standard 45-70 case necked resized to 44cal is going to hold slightly less powder than the 45-70 (about 97.5% of parent case). Pretty much a wash in ballistics between the two (45-70 & 44-70 Maynard based on the 45-70 case).

I had a rolling block made up in 44-70 maynard using a reamer designed by Dan Theodore. I think still have the reamer.

Nice. My 40-65 was chambered with a DT designed Dave Manson reamer that I traded to John Taylor for some work and it has an excellent profile. Are you renting it out? Is it a Dave Manson reamer? Will you be shooting Friendship BPCR the weekend of April 18/19? Am planning on shooting on Sunday.

Yes, I'll be there and you are welcome to use the reamer. If for some reason you don't make it, I would be willing to mail it to you. Jim

Thank you. That is very generous. The quoted delivery for my 44cal barrel is late October, so no hurry on obtaining the reamer. Will look forward to meeting you on the 19th. Am getting in late on the 18th and staying/shooting with Woody.

Dr. Maynard,

  Yes I did pursue the 44-70 Maynard. A friend had a Shiloh 1874 Sharps that John King had rebarreled for him in the 44-70 X 2.200. I purchased it and have been quite impressed with the accuracy and ease of finding a black powder load that was all I could ask for in accuracy and ease of loading. I ordered a BACO .446 diameter mold and a set of CH4D dies and took the rifle as a backup to the Quigley last year. While there I documented sight settings for all the targets and shot it enough to know that I made a good decision when purchasing the rifle. I have since built a rolling block for a client in the 44-70 Maynard and have talked with several other shooters using this cartridge. All agree that it is a versatile round and a good alternative to the 45-70. When Green Mountain did not have any 45 caliber barrels in stock they always had the 44 barrels and I encouraged several shooters to go the 44-70 route. All in all a good substitute for the 45-70, I would be happy with either one but the 45-70 has more molds and components available.

Actually Sam, there are a number of 44 molds available from Accurate molds and custom mold makes should be able to easily take any 45 design and shrink it to 44. Wads and punches are available. The only thing I don't see a lot of is cleaning rod jags, but those are easily turned out on a lathe if need be. 
The one big thing that bothers me is that very few shoot a 44 and those that do say it will shoot lights out and is easy to find an accurate load. 
I just had a roller rebarreled from 45-70 to 44-77. I would have gone the 44-70 route if it were not for fear of getting cases mixed up with my 45-70 and 40-65. Well that and I wanted something different and cool and the 77 is hard to beat on the cool factor.

While am waiting for a Krieger barrel, did check with GM and they have the heavier 44cal barrel 'on the shelf' if one is interested in an 18" twist. As am building a long-range rifle, decided to err on the side of a tighter twist and Krieger was fine with making a 17" twist barrel. Their lead-time was the same, regardless of twist. As mentioned, any of the "known" mold makers will make up a 44cal bullet mold. 44-70 Maynard shooters of the world unite!! Wink

S.S. Sam---

Thanks for your up-date on the 44-70 Maynard cartridge project.  I really appreciated receiving your first hand experience.  I have not found extensive usage of the 44-70 reported in long range match entry forms for matches held along the East Coast; but I don't think that is because it is not a worthy candidate, as much as it is shooters haven't made an effort to become familiar with it's possibilities.

Thanks again
Dr.Maynard
