Note: There are a few issues which arise from brass sources. For example, if you are making 22 BR from Lapua brass, you’ll want a small rifle primer. And the 6.5 Creedmoor is not listed (it uses Large Rifle primers for most brass, but Small Rifle primers for Lapua brass). There are a couple other oversights, so we recommend that you double-check your brass before you buy a truckload of primers.

Norma Offers Seven New Types of Cartridge Brass for 2014

Editor — Sat, 21 Dec 2013 18:17:38 +0000

Norma is making a big push to expand its presence in the North American market. As part of this effort, Norma is introducing seven (7) new types of cartridge brass for 2014. We’re pleased to report that Norma-USA will be importing top-quality brass for the 6.5 Grendel, and 6.5 Creedmoor, two popular target cartridges. In addition, for 2014, Norma will offer 7mm RUM, 7mm Blaser Magnum, 300 AAC Blackout (300 BLK), .300 RUM, and the .338 Blaser Mag. The Norma brass we have shot in other chamberings (6 PPC, 6mmBR Norma, 6XC, .243, 7mm RSAUM) has all been excellent, giving good accuracy. Case weights were very consistent and the neck-wall thickness was very uniform, particularly with the PPC and BR brass. The new 300 BLK brass is an important offering for AR shooters. (NOTE: You can also make 300 BLK cases from Norma or Lapua .221 Fireball brass).

Though the annealing “shadow” may not be as visible as with Lapua brass, the case necks of Norma brass cartridges are indeed annealed near the end of the manufacturing process. This assures more consistent neck tension — something critical to accuracy. Most of the new cartridge brass offerings should be be available at vendors by early April, 2014. You can get Norma brass from Bullets.com, Grafs.com and Midsouth Shooters Supply, as well as many other online vendors.

New Norma-USA Brass Offerings for 2014:

6.5 Grendel
6.5 Creedmoor
7mm RUM
7mm Blaser Magnum

300 AAC Blackout (300 BLK)
.300 RUM
.338 Blaser Magnum

New Ultrasonic Cleaning Machine from RCBS

Editor — Fri, 20 Sep 2013 18:00:07 +0000

Using ultrasound in a liquid solution, you can clean your cartridge brass inside and out. Ultrasonic cleaning is nothing new — we described this process years ago. But with the increased cost of brass, more and more shooters are turning to this effective process to get their cases clean.

Now RCBS offers an affordable Ultrasonic Cleaning Machine with some great features. The new RCBS machine boasts a 3-liter capacty, user-friendly keypad, and a built-in 100-watt heater with four settings. The unit also includes a handy drain valve and drain tube.

Ultrasonic cleaning works fast, without the long processing time (and dust) of conventional tumbling. Cleaning cases with ultrasonic machines has become very popular, as the ultrasonic process reliably removes caked-on carbon and grime from brass cases inside and out, even in the primer pocket. We do recommend that, after ultrasonic cleaning, you consider using a dry neck lube to restore lubricity to your necks for the first and second firings.

The new RCBS ultrasonic cleaner features a large 3-liter capacity, 60 watt transducer, and 100 watt ceramic heater. ‘Street Price’ for the RCBS ultrasonic machine is under $150.00, and this unit qualifies for RCBS Rebates ($10 off $50 purchase or $50 off $300.00 purchase). RCBS also sells 32 oz. bottles of cleaning concentrate that will make up to 10 gallons of Ultrasonic Solution.
