Not too long ago our Web Host completely changed the way the site is updated and edited.   I have not worked with the new system and I am having to learn it from scratch.   I have learned to add text and change photos in some cases, but I have not been able to add documents yet and some other essential items.   Since there are over 70 pages and links on the site, and I am but one man, and I am not a web designer by profession, bear with me please.  It is not something I can do in a matter of days.   Most of the main pages I have been able to get updated, but many of the others that are within those pages I have not been able to update yet.   Terminal Performance, Additional Research and some of those are proving to be a challenge, especially getting new documents uploaded and in place.   

My apologies for falling behind on this and I will continue to reconstruct and hopefully get everything back up and running again.

Thank You


The B&M rifle series was conceived in 2005 by William V. Bruton (The B) and Michael McCourry (The M). Billy originally wanted a .500 caliber cartridge on par with the 500 S&W, only in a short handy rifle. Some quick research brings us the 50 B&M Super Short to fit this criteria. Michael having just come off a safari in Tanzania where an encounter with a hippo at extreme close range with a Winchester M70 458 Lott gave him some ideas about a rifle that handled better than the traditional big bore bolt gun that weighs 10 pounds or better with a standard 24 inch barrel. From this concept the B&M Series of rifles and cartridges became reality.

It has taken a little time, but now we are able to offer you the B&M Rifles and Cartridges. I try to keep dies on hand from both RCBS and Hornady, brass and custom bullets are available along with all load data, for the various B&M cartridges. If you are a handloader you are ready to start shooting immediately upon receiving your rifle.

For those that do not hand load, Custom Loaded Ammo can be available to you through Superior Ammunition.

All of the B&M series rifles are built by SSK Firearms 740-264-0176. They have all the reamers, and extensive experience building these rifles, the work is guaranteed and backed up 100%. At SSK Quality comes first!

Note that the 500 MDM, 50 B&M, 50 B&M AK, and the 50 B&M Super Short are true .500 caliber.

The 50 B&M, 475 B&M, 458 B&M, 416 B&M, 375 B&M, and 9.3 B&M are all built on Winchester M70 WSM actions with barrels from 18 to 20 inches. Rifles weigh 6.5 lbs with the Winchester Ultimate stock, 7.5-8 lbs lbs with the Accurate Innovations wood stock.

The Super Short B&M cartridges are built on Winchester M70 WSSM actions. Currently available is the 50 B&M Super Short, 475 B&M Super Short, and 458 B&M Super Short. These rifles have 16 inch barrels and weigh 6.25 lbs with the Winchester Ultimate Stock.

For the lever gun enthusiast we have the 50 B&M Alaskan. A true .500 caliber cartridge that calls either a Winchester/Browning M71 or a Marlin Guide Gun home. Both come standard with 18 inch barrels and the cartridge is capable of 500 gr bullets at 1850 fps. A powerful lever action package.

Our Big Bore stopping rifle is the 500 MDM. Based on a full length Winchester M70 it gives the shooter more power than a 500 Nitro Express on a bolt action rifle with 20 inch barrels and weighs in at 8-8.5 lbs depending on the stock.

Much more detail can be found under the individual pages for each rifle and cartridge.

As stated above all rifles are built by SSK Firearms. You are free to contact them direct and they can handle your rifle from beginning to end, and have access to all the dies, load data, and brass. I will also be available to assist in any way that I can.

We have chosen Accurate Innovations as our only Wood Stocks for any of the B&M rifles. There is no other stock that will handle the recoil of some of the larger bores better than an Accurate Innovations stock. AI has all the specs to build your stock for all the B&M Rifles.

For each of the B&M Cartridges we have designed specific bullets for each cartridge that will accomplish any mission that you ask of them. These bullets are available from both Cutting Edge Bullets and North Fork Technologies.

I personally am not in the gun business and don’t want to be. I am a shooter, hand loader, and hunter, the same as you. I developed these rifles and cartridges because of a personal need for something to satisfy my needs and objectives, and I have been extremely successful and lucky in the B&M adventure, and it is my desire to share it with other shooters and hunters. 


I am available to you for assistance and am more than willing to help out in any way that I can. Use our contact form on this site or email me direct at for any questions!

Thanks for stopping by and I hope you like what you have seen! Please Stop by and sign in on our "Guest Book" and let us know what you think.
