6mm BRG Specifics

Many of our readers were interested in the 6BR Improved cases with a longer neck than a Dasher, such as David Stipling’s 6 BRDX and the 6 BRG from gunsmith Billy Dale. At our request, Billy measured his 6 BRG wildcat and provided us some additional details. It has slightly larger capacity than the 6 BRDX. Fire-formed 6 BRG cases (Lapua Brass) offer 40.6-40.8 grains of H20 capacity, just a little bit less than a 6mm Dasher (41.0-41.3 grains), and about 2.5 grains more than a fire-formed 6BR case. The 6 BRG neck is .264″ long, just about .058″ shorter than standard 6BR brass. That gives you plenty of neck to seat both long and short bullets, and to “chase the lands” as the throat erodes.


Billy reports: “The 6mm BRG was designed by myself and Dr. Robi Robinson as a 1000 yd competition and long range varmint cartridge. The neck is about .250″ and the body taper is reduced to .010″ (.005″ per side). The BRG fills the gap between the 6mm BR and the 6mm Dasher, giving the shooter a neck length of .264″–somewhat longer than the Dasher enabling him to seat VLD bullets out further to chase lands as they wear. Varget Powder works extremely well in the BRG and with a 28″ Lilja 3 groove barrel, you can push a 105gr VLD bullet 3100+ FPS with extreme accuracy. On a recent varmint hunt in Kansas with one of my clients, I witnessed many kills from 700 to 1120 yards with this gun and cartridge. For more info, I can be reached at 804-314-6787 or BDRCustomguns[at] My website is”

Dave Kiff at Pacific Tool & Gauge created the reamers for the 6 BRG and a 6.5 mm version, and a reamer print is available in PT & G’s archives.

Better View for Balance-Beam Scales

Even in today’s digital age, many reloaders prefer the simplicity and reliabilty of a balance scale for weighing powder charges. In this Bulletin, we reported that our own PACT digital scale suffers from fluctuating read-outs. The weight reading drifted up to 0.3 grains in less than an hour. (PACT Story). LTRDavid has come up with a clever upgrade to an O’Haus-type scale that makes the weighing process easier for those of us with old eyeballs. He’s simply mounted a magnifying glass in front of the balance marker, using two clamps. Pretty ingenious wouldn’t you say? We wonder why the scale-makers didn’t offer a small magnifier as a factory option long ago. For more smart reloading tips, check out David’s website,

Redding Balance Beam Reloading Scale

When working with balance beam scales, be sure you have the device leveled. Even a small amount of tilt will throw off the measurement. We’ve seen folks who keep their scale on a shelf or storage area, and then take it out for use. That’s fine, but remember than your loading bench may not be uniformly level on all sections. Unless you put the scale in exactly the same place on the bench every time (at the same angle), you may have to re-set the level. Likewise, if you take the scale to a range, be sure to re-level it to your new working surface. And remember that is it just as important to level the scale front to back as left to right.
