Met a salesman today for a company called LeMag Firearms LLC. He was showing the local shopowner an AR rebarreled and chambered for a cartridge called the .45 Professional. Round is made from .284 Winchester brass & puts a 230 gr. bullet downrange "at 3000+ FPS". Winchester is to provide brass and LeMag will load in a 230 gr. truncated cone (flat point)FMJ & a 230 gr. Hollowpoint. Uses standard AR mags. Sales guy says they have been demoing to the Army at Benning and Knox.

Anyone interested can contact LeMag at 248-634-1312. I am not associated with this company.

There is a whole article on this company, showing the .45 Pro cartridges in comparison to .223 and displays LeMag's other conversions in the Guns & Ammo 2000 Annual, pages 44-47 (which probably appeared at one time in a regular monthly issue.) The main guy is Tim LeGendre. There is even a statement about his conversation with Eugene Stoner as Stoner denied that this (the .45 Professional round) could ever be done, but LeGendre did it! Also includes a cool brief about an M1 Carbine converted to .45 Win. Mag. and .50 A&E, among other conversions (M14 in .338). Check it out; very cool.

He can also do the .45 Professional in the Ruger Mini 14 which I forgot to mention, probably because I wouldn't be caught with one <G>.

Are these numbers right? That'd be a pretty impressive cartridge! R

The lit sheet he gave me says 3000+fps and that is the number he gave me verbally.

Though I like the simplicity and ruggedness of a Mini-14 or Mini-30, I don't think I would trust the integrity of a Mini-14 barrel bored out to .45. Unless he has replaced the barrel with his own fabrication, it must have a really thin wall. (I also wouldn't trust the M1 carbine in .50 A&E for the same reason). I would like to see him build a .45 Pro Sniper-Tactical bolt action, with a more pointed bullet tip. It would not only be easier to create than the semi's, but it would be more practical for frequesnt use. The accuracy (because of the weight and speed) would be oustanding!

All of the weapons chambered for the .45 professional have new barrels according to the rep.

Just looked thrpugh my Speer No. 10 manual (yeah I know its old but its handy). To my knowledge no one makes a .451" pointed projectile. Would probably have to be a custom.

Don, this is impossible! A 230gr. .45 bullet at 3,000 fps from an AR? This cartridge is based on a shortened .284 Win. A .284 Win. can't even propel a standard .284" 170gr. bullet at much more than 2,600fps! How the heck are you going to shorten the case, insert a .45 cal bullet of 230gr., and get 3,000fps????!!

I've heard Johnny Rowland advertise his .460 Rowland carbine as having the ability to shoot a 230gr. bullet at "half of 3,000 fps". Talk about WEASELLY WORDING!

These .45 cal "Super ARs" will throw a 230gr. at about 1,500fps. I don't know if you could even propel a 230gr. slug to 3,000fps in a case like the .458 Win. mag!

I never said I could launch a projectile that fast. Just reporting what the LeMag flyer and the salesman said. Contact Lemag for the answers.

Sorry, but that's the best answer I can give you.

Just heard from Johnny Rowland. He claims 1,900fps from the MechTech carbine with a 185gr. pill! And I think this is HOT HOT HOT!

I don't think 3,000 plus fps is possible with a 230gr. bullet!

Don, do you have the physical address or website address of LeMag? I'd like to hear their story .... and THEN call them LIARS!

Sorry, not trying to "kill the messenger"! I've heard this same claim made by LeMag! Don't believe it!

Regards! DaMan

For some reason, this company sounds really familiar. I recall reading about something very close to this a few years back, but I didn't note if there was a web site. Not sure if I have the mag somewhere in this hole........

I am loading MAX loads for my 45-70 Guide gun and only getting 2100 fps out of it. A 284 case is way too small to get 3000 fps. as a matter of fact the .458 case might be too small.:confused:

Yep, Tony got behind on living running tromix so he shut it down
Marty Weems (s) is the designer of the cartridge, Tont thought they were cool so he had a liscense to build them (copyright). They are awesome!

Well, the April 2002 issue of Gun World has a nice story about the .458 Socom. It covers it's historical development, brass sources, dies and loaded ammo. Also lists Tromix as a contact still.... must have been done a few months back to make this issue..... things have changed.

I'm figuring that there will be some inquiries about the .458 Socom after this.

It's hard to 'live' when one is running a business..... I'm in agriculture (apples.....market sucks right now for us growers). I ended up getting part time job just to get some 'spending' cash. Still young and dumb..... figure I got a little time....:rolleyes:

I have read a few articles on various custom conversions done by LeMAG Industries: Including an in depth article on their 45 Professional conversions for AR-15s. The rifle had an 18" barrel and was chronographed with a 230 grain .451 (45acp) projectile at 2950 fps. This is very impressive ballistics. This is on my "to buy-have built" list. After I get my Barrett Light 50, and Shrike belt and magazine semi auto "SAW" AR conversion unit. Once those two new "toys" are paid for. Then I will get a 45 Proessional...so around 2010 or so.

No from all my "research" no one makes a low drag/high coefficient .451 projectile. Let alone one within 200 to 250 grain. This would have to be constructed from scratch. But I believe that such a combo: 3000 fps and extreme low drag would give 338 Laupa ballistics plus the added caliber-diam increase. Using pure copper on a micro-lathe might be the answer? It would take some R&D to get the exact projectile. But an AR-10 converted to 45 Professional (or 45 ProLong..my own pet name) would allow for a match rifle to be effective out to 1200 to 1500 meters? And think of the GPMG chambered for such? Half way between 7.62 and 50BMG ballistics. As soon as I get further allow with this project. I will let everyone know.Anyone interested feel free to email me
