Big bore AR

I think you have a typo.

Obviously.

Glad you didn't take my post wrong.

Looked like a Nube looking for info so I wanted to make a correction.

Just shopping bullet prices is keeping me from going 458. The 450BM and Beowolf are both a bit more than half of 458 (SGammo).

Leaning toward 450BM because of ammo choices. Any big reasons to go Beowolf instead?

I was struggling over which big bore cal to go with as well. Instead of beating my head against all the Internet info anymore I just bought the one with the cheapest factory ammo, 450 bushmaster. Got a complete upper from bear creek for 289 delivered. Mixed reviews on the web but with a lifetime warranty I figured what the hell, I’ll gamble on it. Took it to the range today with factory 450 Hornady Black 250grs and all I can say is wow! My
New favorite rifle. Slapped the upper on a Quentin Lower I had and had 1-1.5” groups at 100 yards no prob with the 1-4 vortex I put on in. Cycled 100% with the lancer 10rd (556) mag I had with me. I couldn’t be more impressed with the set up. It’s a hammer on the shoulder but well worth it. A blast to shoot!
Long story short, i think you’ll be impressed with any of the 3 choices, but 450 bush is much more affordable to shoot on factory ammo.

50 Beowulf is a badass round out to 135 yards with my 18” barrel. Anything further then it tends to be a lob round.
For just swapping out a AR15 lower, BCG to 7.62x39 & opening up the ejection port, it’s a handy caliber to have on hand.
The 50 Beowulf stops feral pigs, good size game, engine blocks & any numb nuts wanting to breech my front door.
GO BIG OR GO HOME!

For ease of use the 458 is best. I like the 50 but components and bullets are hard to get at times. 450 bushmaster uses 451 caliber bullets so it's fine for a blinker or light game but I prefer the 458.
