.510 Beck ammo (690 grain sub sonic)

Anyone seen this? Looks awesome, but I wonder what the upper and anmmo cost.

The .300 BO's big brother. Interesting. I'd be curious to see what kind of terminal performance that thing offers.

490gr @ 2500fps?

I looked at this at SHOT show in Vegas. It's crazy big. I thought about offering some ammo on this also.

I built a wildcat to fill the same roll. I used a 50 Beowulf case blown out to 510 and use surplus 50 BMG bullets (ball and API). The API is a lot of fun. I used a savage long action, reworked the internal mag to hold three, and built a custom suppressor. It makes a very nice whoosh as it cuts through the air and a thump when it hits




Next to a 223

BCJ, have you shot anything with that beast? I must say that's an awesome looking round and gun.

Murica!!!!

I haven't shot anything living, plan to take it hog hunting eventually

Have you shot one through a chronograph yet??

It will go through schools.
