MDWS GPC (General Purpose Cartridge) Lineup Has You Covered!
The MDWS GPC was designed to make full use of the case potential of the 6.8SPC, while still allowing for smooth feeding and extraction in an MSR. Similar to an "Ackley Improved" cartridge, but not as dramatic, the case taper is slightly reduced and the shoulder angle is changed, resulting in increased case capacity. (Please see photo to left - the loaded case is a standard 6.8SPC, the fired case to the right is an MDWS 6.8 GPC case). Similar to the Ackley method, 6.8SPC ammunition can be fired in the MDWS 6.8 GPC - so you will always have "ammunition on the shelf at your local gun shop" and, by doing so you fire-form your cases for maximum reloading potential. (Remember the 6.8SPC ammunition will headspace at the neck/shoulder junction of the GPC chamber, so please practice safe headsapce measuring methods).
Since even the pioneers of the 6.8SPC agree it will not become a military cartridge, we may as well get the most out of the case as possible; no need for so much taper and no need for the 23 degree shoulder angle. The 6.8SPCII boasts approximately 50-100fps gains over the original 6.8SPC, and the GPC boasts the same over the 6.8SPCII. If those that promote the 6.8SPCII over the 6.8SPC stead fast with their reasoning for same, then the MDWS 6.8 GPC only provides yet another opportunity to truly benefit from such a great case/caliber combination! No more confusion of the SPC or the SPCII (which has multiple chamber variations depending on manufacturer) - it's all too confusing, and SAAMI only recognizes the original SPC so factory ammunition is stalled at the SPC's performance.
Even better yet, those with 6.8SPC or 6.8SPCII rifles can ream their chambers to MDWS 6.8 GPC to reap the benefits - as long as it is a Stainless Steel barrel, NOT a Nitride/Melonite/QPQ barrel (that would destroy the reamer).
Please stay tuned for all of the performance updates, MDWS barrel options and the chamber ream/re-stamp services we will offer for those with 6.8SPC/6.8SPCII barrels that wish to "step up" to the GPC!
It all started with the conversion of the 6.8SPC to the MDWS 6.8 GPC. Now, we will be offering a full complement of cartridges based on the MDWS GPC case!
