Bastogne Stock by Accurate Innovations
The 50 B&M is a true .500 caliber cartridge.   It is designed for the Winchester M70 WSM control feed action.   The parent cartridge is the Remington Ultra case cut and trimmed to 2.25 inches.   Rifles have 18 inch barrels and weigh 6.5 lbs with the Winchester Ultimate Stock, and 7.5 lbs to 8 lbs with Accurate Innovations Wood Stocks, which are highly recommended.  With an overall length of 38 inches this is a very handy and powerful package.    When it comes to fast handling and heavy punch, the 50 B&M is in a class of it's own.

The 50 B&M is capable of 500 gr Bullets at 2150 fps, or better.   A powerful, but fast handling package.   

I have done more field work with this cartridge and rifle than all the rest combined, it had to most to prove as there are few or no real .500 caliber rifles on the market.  While the 50 B&M is capable of shooting all available commercial .500 caliber bullets, these bullets do not qualify as dangerous game bullets in most circumstances.    Between JD, Brian, and myself,  we were able to come up with several custom bullets that are suitable for all dangerous game.    These bullets are available and have been tested  extensively both in the lab and in the field.

50 B&M Ruger Alaskan

Below you will see the first ever B&M built on a Ruger Alaskan.   The rifle belongs to Mr. Jake Lasken.    Jake wanted a 22 inch barrel and will be using his rifle for a comprehensive article he is working on.   He will also be doing some extensive load data involving many different sorts of bullets that are available, including some very large cast loads.   Jake will be visiting with us in May this year and I am sure we will be doing a lot of work with the 50 B&M in his rifle, and some of ours here.

Cutting Edge Bullets

500 gr CEB BBW #13 Solid and 450 gr NonCon

Recently we have changed the cavity on what was the 460 BBW#13 NonCon and it now weighs 450 grs.   We made the cavity wider for LVSP, or Low Velocity Shear Point.  I have tested this bullet down to 1500 fps now and blades shear perfectly, I have not had time to test below that velocity yet.   This is a big improvement over 1800-1900 LVSP.

North Fork Technologies

For 2012 North Fork has improved on the Nose Profile of the FPS, or Flat Point Solids, for all calibers, including .500.

I have pressure trace data on the 450 North Fork CPS with some amazing results.  Much lower initial pressure than I thought.  I was able to take the 450 North Fork CPS up to 2365 fps in a 50 B&M with 18 inch barrel, safely, and stay under max pressure.

Article in Australian Shooter by Daryl Lenkic about the 50 B&M

Australian Shooter.pdf (PDF — 3 MB)






I think Daryl did an excellent job on the article above, and now he has taken it to the next step, going to the field with his 50 B&M.   Daryl wanted to go to Africa with the 50 B&M and I hooked him up with long time Friend and PH, Andrew Schoeman.  In fact, this is July 2011, and I just returned from an incredible Safari myself with Andrew, using the 500 MDM and 458 B&M with great success.   Daryl has taken buffalo and hippo with the 50 B&M and I will let him tell you about it!

Michael
.50 B&M performed very well on both buff and hippo. In each case first shot was the 470grn HP with a 515 solid following to speed the ‘quietening’ process.

Buff presented standing face on and took first shot in the chest, which
broke the shoulder and passed through one lung. Put the bull face on the
ground bum up turning in a circle. Solid hit him in the right hind quarter
after he had spun 180 degrees, and solid passed through the length of the
body, through the other lung, exiting low on the neck. Game over. Found
five of six petals from the HP in the shoulder area but not the main
projectile. Range 57m.

Hippo was taken standing broadside with HP punching through the shoulder,passing through the top of the heart and smashing the outer ribcage on the opposite side. Solid followed up in the right hind quarter and is believed to have ended up in the stomach, somewhere amid the vast quantity of digesting grass. Hippo shot on land but made it into the water where he collapsed about 10m from the shore in knee deep water.
Recovered the HP projectile but not the petals. Range 47m


Here is an Article Daryl did on this hunt.
