Ok...Could an 1895 Marlin be rechambered to work with the 458 SOCOM round?
Seems as though the ammunition performance would be close to a 450 Marlin round in a smaller package. The case head should work with the 308 Marlin bolt, but can the action handle the 458 SOCOM pressure? Thoughts? |

My guess would be that the round would have too short of an OAL to cycle correctly in an 1895 action. Maybe a short action Browning BLR would work better? |

It's technically not rimless, it's a rebated rim, but it's sized the same as a 308 bolt head, so i'm thinking is should work with a 308 bolt face.
I may have to get some 458 dummies and see if they cycle. If anything, the rebated rim may cause a problem with the cartridge stop when the rounds exit the mag tube onto the lifter. Hmmm...the brain is grinding this morning... |

Just to have something different.
I think a 458 could approach the 45-70 standard power levels, but certainly not the hotter handloads. Most 458 data is based upon a 16" barrel. You stretch the barrel length out to 20-22" and I think some of those velocities will come up close to 45-70. 458 is a bottleneck round and is more efficient in a smaller package. You should get 2-3 more rounds per magazine and it should feed a little smoother. The 458 can handle rounds up to 600 grains, and I think it will handle subsonic stuff easier/better than a 45-70. I already have a 45-70 and it's a great setup, was just thinking about something different. USSA-1 |

My 300 grain loads in the 458 socom run around 1850 -1900 with out any pressure signs . I havent started reloading the 45/70 yet Im still gathering supplies . I have owned the socom for 5 years and it has been devasating on deer and yotes I expect the 45/70 to give me a bit more . I bought some 300 grain 45/70 that were suppose to be in the 1800 fps range and they were a pleasure to shoot . so here is my arfcom solution . get both.
45/70 
458 socom

Cheaper, less work, more reliable = Rossi M1892 in .454 Casull. .454 Casull ammo is more readily available than .458 SOCOM and you can always use .45 “long” Colt ammo. thats your opinion and your welcome to it but no thanks on the rossi my socom is 100 percent reliable and ammo isnt an issue . I have a big bore lever gun for my john wayne moments but thanks for the comments. |

He's saying that a factory Rossi '92 in .454 Casull is going to be cheaper, less work, and more reliable than the Marlin 1895-based.458 SOCOM conversion that the OP is talking about. Posting up pictures of your fancy AR and bragging about it is nice, but do remember which section of the forum you are in.

Get a 35 Remington 336 bolt and extractor. The lifter will need some welding and massaging. Look at the back issues of Precision Shooting Magazine where McPherson talked about his 1894 50 AE and other conversions - it will tell you most of what you need to know. I added a rim cutter on a 458 SOCOM chamber reamer. Using 50 Alaskan brass formed in 458 SOCOM dies and trimmed up works a lot better in the #1, Encores and lever rifles. Indiana legal hunting cartridge, otherwise not worth the effort. |

For that matter a Rossi 92 in .45 Colt will handle loads stout enough that you won't want to shoot many of them in such a light weight gun. |

I think an off the shelf .454 Rossi would be almost as powerful as a .458 SOCOM, and more reliable/less work than: Kind of a pain to rechamber, you have to cut off enough of the barrel tenon - you might as well just start over.
