A long time ago Federal made center-fire ammuntion under the Monarch (or was it Monark?) brand. Came in red boxes with blue and white labeling. Seems to me that I've read of Balkan-area ammunition that may be coming in under the the Monarch brand. Best thing to do is ask to see a box and check its origin...
I have used Monarch Ammo before in my 30-30 as well as my 9mm pistol. It comes from Academy Sporting Goods. For the 30-30, it was a much weaker round than Remington core lok as well as the Winchester 30-30. I was sighting in my new ghost sights and when I zeroed with the Monarch at 50 yrds, I went to Winchester 170 grain, and I was six inches higher. There were 2 occasion that the spent monarch round got stuck on the breach and it took a heck of a time getting it out. The brass expanded after I fired the round. I only shot 20 rounds with my 30-30 and will never use it again. The ammo is very dirty (both 30-30 and 9mm) and the rumor is that it is corrosive, so you will have to clean you firearm immediately after using the ammo.
For my 9mm, I use the brass Monarch for practice because it is cheap and I have not had any problems with mi Springfield XD, but it is very dirty and I have to do a throrough cleaning of the handgun when I am done.
Where is the Monarch ammo from Academy made? I think that is the brand name that Canadian Industries Limited sold centerfire ammo under at one time. They loaded some rounds that were obsolete in the US at the time - .38-55, .32-40, .32 rimfire, and .22 Savage Hi-Power.
I still have a few boxes of their C.I.L. .22 Long ammo sold by Oklahoma Tire & Supply stores back in the 60's. They also sold Canuck brand shotgun shells.
I got about 6 boxes of it sitting here at my house I bought for nothing more than sight in ammo izhave shot about 2 boxes out of my 30-30 and shot 2 boxes out of my CZ 9pm all of it went bang didn't have any issues with the ones I got!!!
I also bought mine at the local Academy!!As for where it was made the ammo was manufactured in Serbia!!!
I've used it without issue. It's very cheap. Accuracy wasn't great. I've used in my AR15 and I think I shot a box or two in one of my 30-30s. For rough sight-ins it's ok but, you need to switch to better ammo for the final clicks. Lately, I've walked past it to spend a few more bucks on higher quality ammo. Remington and Winchester ammo for the 30-30 is so cheap, I see no reason to cut corners.
