BTB Forum,

I am very interested in the Brockman's .50 Beowulf, but need more information about the rifle, cartridge, and company. I am e-mailing Brockman's for additional information, and will share what I learn. This carbine could be a light, compact. and rugged, big bore with good power. The concerns beyond basic design and execution quality for both rifle and cartidge are bullet availability, suitability, and sectional densities in a large bore. Four hundred grains is a heavy bullet but in .50 is only a SD of .220. I would also be concerned if the advertised performance was only acheivable at proof load aproximating pressures.

Fireplug,
Looks similar to the 500 Linebaugh.  Mr. Linebaugh quotes:
350 gr. LBT cast 1450 fps;

410 gr. LBT cast 1350 fps;
 
450 gr. LBT cast 1300 fps
 
All data from a 7.5 inch barreled tuned Ruger Bisley.

alyeska338,

Thanks, for the comparison to the Linebaugh this gives some perspective to the .50 Beowulf's performance. This is essentially, by comparison, a king sized handgun type catridge; rifle cartridge pair much like a Ruger 77/44 that has really been eating its' spinach.

Fireplug,
Or eating it's steriods.  Actually if you look at the increased barrel length and maybe using a little slower burning powder, it may be a 500 Linebaugh or a 500 Maximum (or Linebaugh Long as it has been called).  It doesn't appear to be in the 50 Alaskan class, but then again, not many are.  Several good 'smiths are converting a variety of leverguns to the 50 Alaskan if you want something in that powerclass.  Ouch.

alyeska338,

Thank you for the information, although this is not the .500 Linebaugh or a derivative you have pegged its' preformance as equal to the Linebaugh if in a carbine. I have learned that this is a rebated rim cartridge with the rim small enough for the minature actions but a short fat case thereafter. Others have also developed a .458 SOCOM much like this. These were first developed as as way to have a powerful round in the AR-15. Why, I do not know but if the upshot of it is a very handy bolt action thumper this is good.

I really like the CZ actions especially the tiny 527 that he is using, if a useful cartridge can be fit in one I want one. Yes, any who wish to can assail me for declaring the .223 as useless except for paper and tin cans and the 7.62x39 for only the cans. I have been working on a 6.5 wildcat to roughly equal the old .256 in this little action, but it is progressing slowly since it is my first wildcat project. Mine would be only a woods companion, but Brockman's is quite the little thumper.

The Remington 600 pointed the way to the benefits of making the action as short as possible to get the job done. I see creating or adapting a useful cartridge for this and other mini actions as the logical progression in bolt action handling qualities.

No thanks on the .50 Alaskan, I agree OUCH!

Fireplug,
Righto!!!  Good research.  I can fully appreciate wrestling with the first time wildcat issues.  I'm going through that myself right now.  Never did understand why the 256 wasn't very popular.  Seems to be a fine round.

Best of luck and let us know how the project proceeds.  It's always interesting to hear of the problems encountered and solutions to solve those problems.
