If not, which large caliber round does? I think I saw it on shooting USA awhile back.

Ok, here's my point. If a larger caliber round that fits in a standard .223 mag is loaded into a .223 20 rounder it will only hold about 10, correct?

Now would it be illegal to pin the mag, even if it only holds 10 .50 caliber(or what ever) rounds?

Just a thought

I've thought about this already...specifically referring to the .458 SOCOM.

I didn't get a solid answer, but if the magazine was stamped .458 SOCOM and wasn't found with 5.56 roudns in it...

50 Beowulf comes with its own uniquely designed single stack, seven round mag which incorporates special features to limit .223 use to 10 rounds

you left out the

"50 Beowulf can also be used in most standard .223 mags. Designed to load 'single stack' in existing .223 magazines and requires no special inserts or adapters. The only modificaiton is that the magazine lips may require slight reshaping in certain magazines to ensure feed reliability."

My gues is that the special mag designed to hold 7 rounds of Beowulf has some ridges/protrusion at the back of the magazine that guides the rims of brass in single stack only. Thus preventing 223 from double stacking.

This modification might be the best bet.

(However you might buy/make floor plate marked with the proper caliber and go with it. Maybe engrave warning sign on the side of mag like "Warning, this magazine is for 50Beowulf/458Socom only.") My opinion=not a fact.

I didn't leave out anything. I've spent a lot of time banging on feed lips with hammers, and all it ever leaves me with is a bad attitude and hurt fingers. Just buy the 50 Beowulf mags.

By the way, nice avatar, this is the guy, right?:

This topic has been covered a few times and often gets posts/opinions by people who probably haven't even seen a Beowulf. So again,

So far all of my 5.56 mags, including the crappy Pro-mags, have worked with .50 Beowulf without any mods. 10 rounders will fit either 3 or 4 Beowulf rounds, 20 rounders 7, 30 rounders 10. However, for some reason the newer Pro-mag blocked off 10/20, that only hold 10 rounds of 5.56 will hold 7 rounds of Beowulf, the older version does not.
