6mm Match Bullet Diameters

There’s been some controversy surrounding the “ideal” 6mm bullet diameter. This is compounded by the fact that 6mm match barrels are available with both .236″ and .237″ land diameters. It has become quite clear to us that bullet diameter is an important variable to consider when choosing the best projectile for your particular barrel. Some barrels prefer “fat” bullets while other barrels prefer “skinny” bullets.

Jason Baney measured 12 different sets of 6mm Match Bullets, including a couple different lots of the same bullet design. Interestingly, Jason did measure the “old” Berger 105 VLD, the “new” Berger 105 VLD (first lot from the new die), and the “new, improved” Berger 105 VLD from the new die, after it was polished. Ten (10) Bullets were measured per type. Each bullet was measured three times (3X) around the largest circumference, normally where a pressure ring would be located (some bullets have a pronounced pressure ring, others do not).

Columns one and two of the chart show the smallest and largest bullet diameters measured for each 10-bullet sample. The third column shows the extreme spread over each 10-bullet set. Note, these numbers are NOT averages, but represent the “low” and “high” diameters for each set. (FYI: Jason noted that while the Lapua Scenars measured very consistently the earlier 2005 “JEVDAK” lot had noticeably smaller meplats than 2007 and 2008 lots.) A Mitutoyo Micrometer was used, zero-checked for each bullet.

H-S Precision Stocks on Sale — $259.99

Now through April 30, 2008, MidwayUSA has H-S Precision stocks on sale for $259.99. These stocks regularly sell for $307.99 at MidwayUSA, and are priced at $350.00-$370.00 on the H-S Precision website. These H-S Precision stocks feature Kevlar- or carbon fiber-reinforced shells, plus a CNC-milled aluminum bedding block. The integral aluminum block provides a solid attachment for the action. Many shooters report that the H-S stock, even without conventional bedding, delivers better accuracy than a typical factory Remington stock. Most smiths, however, believe that the H-S aluminum bedding block works even better when skim-bedded.

Six different H&S stocks are available for $259.99: the sporter-style model PSS003 (short) or PSS010 (long) for Rem 700s, tactical-style model PST012 (short) or PST087 (long) for Rem 700 actions with varmint contour barrels, the PSC100 benchrest style with 3″-wide fore-end for Rem 700 short actions, and the sporter-style PSS021 for post-64 Winchester Model 70 actions. In addition, the PSC027 Silhouette Thumbhole stock for Rem 700 short actions is offered for $269.99. All H&S sale stocks come in black only, glossy black for the PSC100 and matte black for everything else.

M. Weaver of Chandler, OK, who purchased the model PST087 stock (tactical long action), gave this review: “Great stock. Easy to change out. The aluminum full length bedding block takes away the need for any gunsmithing and allows the action to be torqued to proper specifications[.]”
