The M1200 cartridge 6.5 Creedmoor is the designated ammunition for the US military’s MRGG-S (Mid-Range Gas gun program-Sniper) weapons system. We are using the Berger Hybrid Target projectile in this offering. Every batch of M1200 HT is range-tested and subjected to lot-level QA to verify velocity consistency and group-size performance. Our development testing included dedicated accuracy and terminal-effect trials in barrels ranging from 14.5" to 22"; the round showed exceptional repeatability and maintained the Berger projectile’s ballistic advantages even from shorter barrels.

J4 Precision Bullet Jackets are the #1 choice of custom bullet manufacturers. They are the most consistent and concentric copper jackets in the world holding an unprecedented +/- .0003” tolerance. The most precise jacket produces a Berger bullet with the least amount of dispersion at all ranges. This is a match projectile but in our experience the terminal performance is quite underrated. 

This round performs exceptionally well in gas guns such as the LMT Mars H, Knight's Armament SR-25, the Geissele MRGG-S, and a host of others. This round is world class.

    High Quality and Consistent

    This M1200 load is absolutely amazing. Out of my Criterion 20" Hybrid, it consistently printed 0.6–0.8" 10-round groups at 100 yards. The SDs were extremely solid as well. PLEASE keep this load in rotation! This round is a winner.
