6.5 Grendel (Small Rifle primer)

1.508 - 1.512 O.A.L.

The 6.5 Grendel was designed for use in an AR-15 type rifle to offer ballistics similar to the .308 Winchester, with less recoil. This flat shooting round utilizes the inherently accurate, high ballistic coefficient 6.5mm diameter bullet. Its short case length allows it to use some of the longer, heavier match bullets, making this caliber one of the best choices for long range shooting out of an AR. With proper bullet selection, this caliber is no slouch in the field either, being suitable for deer-size game as well as varmint hunting.

Conversion of an AR to 6.5 Grendel requires a new bolt, barrel and magazines to feed the larger diameter cartridge. Several companies offer completed AR uppers and firearms, and reloading dies are readily available. Several manufacturers are now producing bolt action rifles in this caliber, many of which are built on “mini” actions, making for a lightweight rifle with plenty of range.

Our 6.5 Grendel brass uses the standard .080" flash hole as opposed to a few companies that use the .060" flash hole.

Starline rifle brass is IMPRESSIVE! I started with Federal factory loads, in my newest precision rifle, to obtain the brass. Since this is for a precision rifle, I match prepp'd the Federal, deburr flashholes (that weren't round and had huge burrs), uniform primer pockets (some only about 65% since they were so uneven) and trimmed (varying lengths) after first firing. I was so Unimpressed that I ordered Starline to give their rifle brass a try since I've had such great luck with their pistol brass. After receiving quickly (THANK YOU!!) I attempted to match prep and found it was completely unnecessary! Primer pockets are flat and uniform, flashhole is round and has no burr as its obviously formed with a punch that rolls it over on the inside of the case. I FL sized the cases and my first 50 were all with in .003" of one another and just under trim length. After some load work up, the gun easily shoots under 1/2 moa (5-shots) and consistently(now that I've loaded and shot most all of the 250 I purchased). Thanks Starline for another fantastic product. I'll be trying Valkyrie brass next! ;-)
