    Thinking of 458 or 450... Need help!!!

    Hey folks, I'm thinking about filling a gap. I'm sure this has been widely discussed but it's new to me.
    The 5.56 Colt & FN, then the Ruger Scout in .308, then ???
    Sold my Marlin 45/70 (I loved the cartridge), so I'm looking to step up in the AR platform to something similar.
    Seems the choice is between 458 SOCOM and 450 Bushmaster... ?? Please help an old dog learn new tricks... THANKS!

    What do you want it to do? Is there a specific game animal, that you plan to hunt, which the .308 is inadequate for, or do you simply want to know each shot costs more than $1?

    Hopefully you reload because none of the megabore AR cartridges have plentiful or cheap ammo.

    I have been looking into the 458 as well. I think it would not be too bad if one reloads. Yes it is an expensive round but it is an interesting concept to have in a AR 15 sized rifle. You do have more more bullet options with the 458 versus the handgun bullet options of the 450. For me though living where I do and due to recent changes to magazine laws, the 30 rnd 5.56 magazine now becomes a legal 10 rnd magazine. That is the main driver for me to acquire a 458 upper.

    Thanks.
    That's been some of my thinking too. I'd really like to go big (Can you say .416 Rigby? ) but the need is no longer there, so I want to stay with the AR platform.
    I don't want a separate rig, so an extra upper in 458 is what I'm thinking.

    I'm just looking to round out my arsenal a bit... If and when the SHTF I'd like to have some options. 5.56/.308/458?
    2 handguns will go, but which rifle accompanies me into the field? Will I need range? Accuracy? Stopping power?
    3 choices I'm thinking, and the 458 seems to slip right in that slot. But I could be totally wrong headed in my thinking, hence the post...
    Of course none of this will likely happen, and, in that case my 'arsenal' will go to the closest neighbor...
    I'm still trying to work this out...but, many thanks for the replies...

    I have a 458 10.5 in and I love it. If you want one you really have to reload. It has a wide bullet selection from 250 to 600 grains. The brass is made by Starline and is readily available with 68 cents ea being the best price I've found. Lots of different powers to choose from with Lil Gun being a favorite. There is a 458 forum that you can go to for lots of great information. I highly recommend Tromix for your barrel/bolt or upper.

    I have a .458 SOCOM upper from Tromix.

    The main difference between the two rounds is the .450 Bushmaster uses handgun (.452") bullets at about 2200fps and 40000 PSI, while the SOCOM uses rifle (.458") bullets at ~2200fps at 35000 PSI.

    If you want to hunt big game with it, get the .458 SOCOM as the variety of hunting bullets available is greater. If you're just going to plink or hunt medium game, get the .450 Bushmaster as .452" bullets are less expensive in large quantities..

    To get the most out of either round, you should reload.

    I need to buy you guys a cigar!
    Great info thanks! I'm saving all this info in my little black book!
    I'm gonna check out the Tromix upper and parts...
    Then I need to look into the cost issue and do my usual comparisons...
    You guys are really great! THANK YOU!

    It will cost you about $700 to get what you need from Tromix, but it will work (as opposed to the uppers/barrels chambered by the PTG reamer).

    That's good advice... I didn't know that... I was planning on a complete upper as I'm not into tinkering any more.
    I've become one of those..."I want it and I want it now!"... kinda guyz... ;-)
