Now then, stick the .45-90 in a Sharps, load it way out, with a snout full of black underneath a 500-550 grain bullet, and that is entirely another matter. I do not own an 1895 so I do not know how long one could go. The case is 3/10s longer. A smith might be able to get it to function with something like a 300 Nosler? However, I just went to the garage and checked some hand loaded .45-70 loads with the 300 Noslers and the shortest ones ran 2.501". Some PMC factory 405 grain RFN rounds ran 2.518-23". Even with the Noslers loaded in the 2.4" case, you would need to get a bit over 2.8" ammo to cycle. Need just a bit longer action. Another consideration is that unless you want to use bkack powder, you can put all the fine Marlin action can stand in the 2.1" cased .45-70. Sounds good, but are you sure you want Remington messing with that. They don't even have what they bought ready to go, working right yet. Good luck, jack

    PS: My 45-70 is a 26" Ruger 1 S-C. I am just getting geared up to wring it out. jt
    I think the OP was referring to a conversion of an 1895 to a 45/90, something that was apparently done before. As for Remington messing with this, they are having enough troubles as it is! :P I don't have the funds currently to spend on tricking out and creating one of a kind guns, and as is the 45/70 really does it for me anyhow. As for other stock caliber Pre Remmy Marlins, yes I could spend some money on those! It is kind of a more bang for the buck thing for me..

    That is a good legitimate purpose. If I could see something smaller than a 40 foot tractor trailer van at that distance I might be interested! My real needs are more on the order of 30 feet, with another 6 or 7 feet of bone crushing penetration after that. 30 feet is the max distance the state of Alaska says is legit for shooting a bear for self defense..

    Deja vu sounds like fun to me...who did the modification. I only ask because I've seen project guns that don't make the grade
    If I had to go bigger than my GG I would get a big custom muzzle loader. I know a guy that built a 63 cal. with a 1 in 39 twist. A guy had him make it and took it to Africa and shot a Elephant in the chest with a 900gr. projectile I guess that would be fun

    I assume the gun I saw was from Wild West Guns. I don't know any one else that does a 457 WWM?

    I would prefer the 45/90 in a lever gun Just because I think it would be fun to experiment with a classic old west cartridge that does not have a lot of modern loads all ready developed for it.

    Re: 45/70 conversions to 45/90 or 457 WWM?

    I have a WWG 457 magnum and wish I had just gotten a 45.70. After spending alot on WWG 457 brass and getting the special dies, I found that I didnt like the extra recoil when loaded to its upper potential with 350 grain bullets. I wound up loading it down to 1945 fps which is in 45.70 performance and this was the best accuracy too. Now I have shot some large animals including Kudu, Gemsbuc and a 350 lb bear with this load and I had complete pass through on all of them with a Swift A Frame bullet. None of them dropped on the spot but all were hit in the boiler room . I dought another 300 fps would have made any difference. If your looking for a defense gun for Grizzly you might as well stay with the 45.70 and use a heavy hard cast bullet and shoot and shoot to break bone because you wont stop a chargeing griz with a chest shot. I am a fan of large caliber bullets espesially in muzzleloaders. 58 and larger round ball is my choice. Now give me a lever action .62 caliber and I will show you a grizzly gun.

    I dont think the 45.90 brass is strong enough for hot smokeless powder loads. I tried shortening 45.90 brass to WWG 457 mag length to save money but was warned on this forum not to do it. I called WWG and they confirmed their 457 mag brass is thicker at the base to handle the higher preasures and 45.90 brass is not heavy enough. I may be wrong but this is what I was told. I have no other experience with 45.90 brass. Surely some people have experimented with smokeless in 45.90 rifles.

    wow If that is the case then I may not be as interested. Ill have to look in to it. I do want some thing in a lever gun that I can experiment with though. I am tired of coming up with a load I love in the 45/70 only to have my father point out the same load in one of his books. I spend several weeks coming up with a load that he finds in 2 min. With the 45/90 (loaded at marlin levels) that wont happen.

    If that is a Wild West Guns, I think they use a stronger receiver (not sure) some one is making a stronger one. Don't know about the brass issue, but special brass special price.

    Re: 45/70 conversions to 45/90 or 457 WWM?

    I have a Ruger #1 that I rechambered to 45-90. What I have found so far is that the cartridge and rifle exceed my ability to absorb recoil. I am using Harold Johnsons loading data for the 450 Alaskan. When you get up into the upper end of his loads, recoil is significant.I have no idea how a lever gun holds with that kind of pressure. I am loading the 405 remington with substantial amounts of 3031. According to his data I am approaching 458 velocities. My Marlin 45-70 is a ***** cat in comparison.

    Re: 45/70 conversions to 45/90 or 457 WWM?

    45/90 was once factory loaded with a 405 gr bullet. Was loaded with 82 gr of blackpowder.
    Currently have two of them. One an original 86 Winchester and a new converted 86 Winchester.
    Old factory loads were roughly 200fps faster than the 45-70.
    Plenty of load data around for the 45-90. Newest data is published by Lyman.
