how far behind the 500 S&W is the 500 Max??? They're quite different, it's hard to compare them accurately. The .500 Maximum has more case volume, larger bullet diameter (about 5% more surface area), and operates at much lower pressures. Here's some figures from Accurate Powder load data to compare. I rounded things a bit because I'm looking from one page to another.... .500 S&W (8-3/8" barrel) 350gr XTP @ 1900 fps, 55k psi 440gr WFNGC @ 1700 fps, 48k psi 500gr XTP @ 1530 fps, 55k psi .500 Maximum (7-7/8" barrel) 350gr WFNGC @ 1650 fps, 35k psi 435gr WFNGC @ 1550 fps, 34k psi 525gr WFNGC @ 1300 fps, 34k psi |

Thanks... I guess I didn't realize the 500 Max was a .510 bullet ( assuming )

Thanks... I guess I didn't realize the 500 Max was a .510 bullet ( assuming ) It's merely a longer .500 Linebaugh (1.6-inch case vs 1.4 for the Linebaugh). I find all that extra pressure (in the case of the S&W) unnecessary from a terminal standpoint. |

at one time I was determined to buy a 500 S&W... but after shooting them every chance I got... I more fell out of love with the X Frame revolver... in fact ( I'll never sell my 357 Max Dan Wesson ) but I've come to not like the balance of the long cylinder revolvers... I guess as I'm getting older I like a "normal" length cylinder & just go to a bigger bore if I need more power... if I'm after more velocity I just go to the single shot handguns...
I have always wanted a .510 revolver though, as a companion gun to my old 50-70 Government single shot rifle... so I could see myself with a Linebaugh or 500 Max down the road, set up so I could share components...
the 500 Max case must be pretty close to the 50-70??? & I'm sure I could use the Linebaugh cases in the 50-70 rifle... though that is my weakest Martini action, so I doubt I'd ever want to use modern pressures in that rifle...

looks like the 50-70 is .015" longer, & has .060 bigger rim diameter than the 500 Max... I have an e-mail into MRI to see about the 50-70 as a chambering from their custom shop, as I already have the brass

Looks like they haven't produced a BFR in 50-70... but I'm in discussions with their shop manager to see if it's possible for their custom shop to do  they are questioning that the cylinder diameter would be big enough... does anyone know if the 500 max guns use a bigger diameter cylinder than the BFR's do  |

I'm pretty sure Magnum Research won't build a .510 of any sort. The cylinder diameter will easily accommodate one of the .510 cartridges. There are a number of .50 Alaskan conversions on BFRs and in fact Lee has done one.

My Huntington built 500 Max has a 1.778" diameter cylinder.  My Gallagher built 500 Linebaugh has a 1.785" diameter cylinder  and my Linebaugh built 500 Linebaugh has the largest at 1.792".  Tim |

There are a number of .50 Alaskan conversions on BFRs and in fact Lee has done one. I spoke to Jack on Monday about doing BFR conversions. When I mentioned the .50 Alaskan, he said he's got two in the works and when they're done he's not gonna do 'em anymore. I get it, test firing sucks and they are neither high demand nor practical. Doesn't mean I would love to own one! 😁 |
