 Cast bullet loads for the .458 Socom/Beta C mag question

I have of cast bullets for my 45-70. Would putting cast bullets down the Socom clog the gas system? Also will the .458 Socom feed from a Beta C Mag? Thanks

I know the Beta C will not work with the SOCOM, but there is a 90 round drum that does work with it.

I have heard of some people using the cast bullets in the SOCOM, but I would assume that it would clog the gas tube eventually

+1

Because when the rounds get to the bottom of the mag tower they seperate into 2 seperate single feeds that go in the spirals of the beta mag...make any sense. Therefore the round would be too large to fit in the narrow area designed for a single row of 5.56.

Artinker,

Please see my notes in this thread regarding Cast Bullets in my 458. Basically it is that I have done limited testing with quality cast bullets and have had no problems. If you are thinking about the el cheapo lead, with questionable lube, well, you are on your own. I know that Cast Performance worked for me, and I would hazard a guess that the Laser Cast bullets might also work. I would also add that if whatever bullet you test, if you are getting any significant barrel leading, then you might be getting the same crud in the gas system. The premium lead bullets that I mentioned gave zero barrel leading and zero leading in my bolt assembly.

Thanks everyone for all the info. It looks like the Beta C project is canceled for .458 . I have a about 500 lead bullets but I can't say they are premium. I finally got my rifle to run with a good load so I will stick to the Hornady's for now.

Artinker,

I forgot to mention on the cast side is that you can visit a couple of levergun type forums, or even Beartooth Bullets forum and get a lot of good data and understanding of lead through any gun. I think the basic formula for obturation (and hopes of non-leading) is something like 2000 times the Brin. hardess is the minimum pressure region that the bullet should like to perform, and not gas cut or seriously lead. Mixed with a good lube, and you should be good to go. I have been losely trying to put together a buffalo hunt (harvest) for the last couple of years, and if and when I do, I will use a cast bullet from my 458.

I think a lead bullet would be appropriate, as I reflect on the fact that the 458 Socom basically duplicates the 45-70 rifle loadings. One of our first military long gun cartridges meets our current military platform. Something kinda neat about that.

Check the Remington bulk bullets from Cabelas
Best deal by far for quantity and they shoot well

Thanks for the great tip on the Remington bulk bullets from Calbelas! I just ordered 405's and 300's. I did not even know they sold them like that. I agree, it is a good deal. I will leave the lead, bullets for the Sharps.

I can attest to the MWG 90 Rounder working for the 458 SOCOM. Just got one from a guy on here last month and took it out to test the other day - have a nice bruise from letting 25 Corbon 300 grainers go out of it as fast as I could re-align the sights and pull the trigger. What a blast! I higly recommend them for the fun factor.
It does get in the way of your support arm though - not enough that you can't use it, but it does touch. I need to install a verticle foregrip and see if that reduces interference.

Does the MWG hold 25 rounds then? Thanks.
