  1. Worth mentioning, especially for reloaders, that the Socom uses a .458 slug while the Bushmaster uses a .452 bullet. Similar, but defiinitely not interchangeable.

  2. I have both the 450-B and the 50 Beo. I have hunted deer with both on multiple occasions. The 450 outperformed the 50 Beo every time, consistently putting animals down quicker and cleaner. This is not to say the 50 Beo isn't good for hunting. As a reloader, I have found that there are simply many more choices for the 450B and have simply not found a good working combination for the 50 Beo as of yet.

  3. I really have no experience with these calibers. Could any of these be considered for use as Anti-material? So far I stuck with 300WM but would love a AR platform semi-auto that could do the job. (I think there are 2 manufacturers of 300WM ar style rifles but they are exorbitantly expensive)

  4. I'm on your email list for a 458 to come back in stock.
    The 50 is after that.
    I figure 2 rifles and 2 pistols a year is ok…. as long as wifey don't know 🤣🤣

  5. My favorite is the 450. I live and hunt in one of the restricted areas, and when my state legalized 450, it changed my hunting completely. It's powerful and accurate while having manageable recoil. Ammo is fairly common, and if you can't or don't want to hunt with an AR, there's plenty of bolt rifles chambered for it

  6. Man forget BUTT CRACK ARSENAL. I ORDERED A LOWER RECEIVER FROM THEM AND ITS BEEN 5 WEEKS NOW AND STILL NOTHING. AND when I messaged customer service they said it usually takes 14 business days so give it some time. And last I checked 5 weeks was way longer than 14 business days

  7. 450 bush is not a straight wall. It is also limited to ar-15 pressures and metallurgy, and uses a small rifle primer. 45 raptor is a straight wall, uses LR primers, identical case as 308, and ballistically superior. 450 was presented to subjugate 45 raptor.

  8. So how come the grendel and beowulf both came from AA but the grendel doesn't seem to need the additional permission from AA that the beowulf does?

    Still think you should standardize on only using grendel bolts for the 6.5g, 50b, and 7.62*39.

  9. Bear Creek make me a 20" bull barrel in stainless with a target crown not threaded in 350L , I love my 18" just want a heavier one bull barrel no threads

  10. Outstanding video, my friend! Appreciate the honest evaluation between these three big bore thumpers. I have been considering a 450 Bushmaster build for some time. Currently, the the price for ammunition in general is making this particular hurdle a little more challenging than normal.

    Thank you again for the videos and the outstanding products offered by BCA. Still waiting for a left side – side charging upper which ejects to the right. 🤔😉

    Have a great week, my friend. 🇺🇸 🦅 🇺🇸 🦅 🇺🇸
