Is there any advantage to a small primer pocket vs. a large pocket? I notice the 6 PPC uses a small primer.

Looking around it appears that Hornady 6.8 cases have the small primer. It also appears that the original design called for small primers. Per SSA the SD of small primers is lower but the large rifle primer gives better reliability in extreme cold conditions.
Have any of you guys used the Hornady brass in your 6x6.8?
Any Difference?
Also it appears Large Rifle primers will give about 50 fps over a small rifle primer.

DO NOT use small primer data with large rifle primers. Pressures will be extreme. In the loads I tried I gained about 100 FPS but pressure was high. As for brass stick with SSA it has been lasting substantially longer than Hornady or Remington. |

SAME CHARGE different cases. I'll go with the SSA brass any day as many of mine are 11+ loadings. I didn't chronograph these. The Remington primers would have me stop right there f I wanted to save the brass. Remington 71/2 SR's and CCI 400 LR's.  Greg |

Typically, SRP'd cases are used by many manufactures to help tame higher pressure loads for a particular round...from a .17 Rem. to a 6.8mm SPC II. SSA is a good example, they also make their own very high quaily brass... |

A LR primer on a 223 head size just won't cut it and in many cases, pun, ala Hornet a LR would be disruptive to performance. Indeed in that case a SP is often used because of that.

Just pointing out one of the primery reasons Greg, I am fully aware that it also depends on case head diameter of a particular case such as the .223 Rem. etc. [As one European General said "don't be a {Rrot Karit}", be a Patriot.] Good Night Gentlemen. |
