AglifterConverting my Mark X in 458 win mag to?
Well, since no one seems to want to buy it... It kicks the heck out of me -- is there a lesser caliber I could simply convert it to w. a rebarrel? (Fingers crossed for 404J)

jimatcatyou don't say what you're shooting in it, but try the 350 gr loads that hornady makes.... lots less recoil...or load it down to 45-70 levels.... put a mercury recoil reducer in the stock... make sure that the stock fits you, change the recoil pad....there's lots of options that are less expenve han a barrel change....

GeorgeSYou can rebarrel to .416 Taylor, .375 Taylor, .338 Win. Mag., .300 Win. Mag., and a number of others.
Or, you can just load it down as jimatcat has suggested.

adrookHell, I was gonna suggest punching it out to .458 Lott

N E 450 No2Why not just loaad it with 300, 350, or 400gr bullets at 45/70 type velocities.
Makes a great deer, wild pig, black bear over bait rifle.
Lots of fun to shoot as well.

swampshooterI load all the way from round balls at bb gun velocity , 45 colt equivalent, original 45-70, high velocity 45-70, to loads that exceed factory ballistics. These loads are all accurate out of my mark x Alaskan. a .458 doesn't kick bad unless you want it to. a very easy cartridge to load for. for sure there's no reason to re-barrel to a 416 taylor as these loads are very easy to duplicate with the .458.
velocity is like a new car, always losing value.
BC is like diamonds, holding value forever.

WhitworthI didn't know you were trying to sell it. PM me with the details if you are still interested in getting rid of it. I might know someone who is interested........

idahoelk101Barnes makes a 300 grn triple shock that I alwasy wanted to try for lower recoiol and increased range.

MileHighShooterIf you're wanting to stay big bore, there is the 375 Ruger, 416 Ruger/AR, 416 Taylor, 425 Express. You won't be able to get the 404J in there without a lot of gunsmithing work, but a 425 Express would give you basically the same ballistics but on the generic Win Mag case
If you think every possible niche has been filled already, thank a wildcatter!

chuck375If a 458 is kicking the hell out of you, a 404 Jeffery might be too much too. I suggest shooting one first. Personally I like the idea of loading it down. Second choice would be to rebarrel to 375 H&H.

jeffeossoload 405 rem JFP at 2000 fps .. its a piece of cake to shoot and easy on the shoulder... right at the top of what a 405 can take, and not even idling for the 458.

ddunnI enjoy shooting cast 405gr bullets with a trailboss. This should not hurt you. If it does, you are not going to enjoy anything big bore.
