Cartridge Support Kit
Every cartridge we offer here at Primal Rights is the center of an entire ecosystem of components and equipment. Countless customers call every year experiencing accuracy/precision problems which are often caused by an improper fitment between the chamber, brass, and sizing dies they have. This is due to no one being responsible for the entire system, because someone different supplied each of the parts and equipment.
If you want to shoot the way you see Greg shooting on YouTube, you need a system... not parts.
Matched reamer, chamber, sizing specifications that are controlled from inception to completed rifle. No tolerance creep from barrel to barrel, because you own your own reamer and have a die made to that exact spec. If you get a new barrel from a smith that uses their house reamer, who knows how many barrels have been cut on that since your last barrel? It might be a completely different reamer. Investing in high end dies, and having your chamber changing all the time is a recipe for disaster. Take control of your ecosystem. No excuses.
* If the cartridge you are interested in above is not listed, then it is currently out of stock. Call for availability questions.
We do not offer cartridge support kits for factory chamberings. Only wildcats that Greg shoots and loves!

BRA stands for Bench Rest Ackley. If you are unfamiliar with the BRA's, I'd encourage you to do some research on the subject and watch our YouTube video on the .20 BRA.
This cartridge dominates short range (sub-500yd) colony varmint applications and will do a great job on coyotes with the right bullet. A 55gr Berger can be launched at 3500fps from a 26" barrel easily.
You start with Alpha Munitions 6 BRA brass, neck it down to 22cal, then down to 20 cal. Fire forming is generally not necessary, but we recommend it. Neck turning is generally not required (though it can be beneficial).
Everything that is true of the 20 BRA is doubly true for the 22 BRA. A 75-80gr class bullet can be launched around 3100 FPS from a 26" barrel and will deliver amazing performance out to 1000yds+.
You start with Alpha Munitions 6 BRA brass and neck it down to 22cal. Fire forming is generally not necessary, but we recommend it. Neck turning is generally not required (though it can be beneficial).
Ruthless Speed.
If speed beyond all reason is your thing, the 20 Primal is made for you. We can easily achieve velocities in excess of 5,200 FPS with a 24gr NTX in a 22" barrel.
This cartridge is based on the Creedmoor parent case, which has been necked down and improved by Greg Dykstra.
Watch here as he demonstrates this cartridge and its insane capabilities. Then give us a call to get a 20 Primal of your own!
You start with Alpha Munitions 22 Creedmoor brass and neck it down to 20cal to set the false shoulder for fire forming. Neck turning is generally not required (though it can be beneficial).
The most definitive coyote cartridge on planet earth. This thing anchors a coyote as if you whopped them with an 8lb sledgehammer. Greg is an avid coyote hunter, and wanted something that would anchor these critters out to a thousand yards if necessary, and do so with authority.
Mission accomplished.
The 22 PRC Primal can launch an 85.5gr Berger in excess of 3650 FPS from a 26" barrel.
You start with 6.5 PRC brass and neck it down to 6mm, then down to 22cal to set the false shoulder for fire forming. Neck turning is generally not required (though it can be beneficial).
The 6 PRC Primal is the best all-around cartridge in existence. From small varmints to predators to pronghorn and deer to elk. As long as you pair it with the right bullet for the job, it will DO the job!
The 6 PRC Primal can launch an 105gr Berger in excess of 3400 FPS from a 26" barrel.
You start with 6.5 PRC brass and neck it down to 6mm and set the false shoulder for fire forming. Neck turning is generally not required (though it can be beneficial).
A very tame Primal. If you want long lasting accuracy at longer ranges, a 180gr 7mm bullet at 2850fps is just what the doctor ordered!
You start with 6.5 PRC brass and neck it up to 7mm, then neck it up to .30cal, then size it down to 7mm to set the false shoulder for fire forming. Neck turning is generally not required (though it can be beneficial).
Two words - Thors Hammer.
The 7mm Norma Mag Improved is the ultimate big and bigger game cartridge. You can reach speeds of 3200fps with a 195gr Berger EOL. Run the numbers on that sometime, and you'll see what we're talking about.
… and unlike bigger calibers, the 7mm delivers that energy to your target animal, crushing them to the ground where they stand. Bigger bullets tend to just pass through and lead to track jobs.
Greg has vast experience on many big game animals over the past 30 years. He knows what works, and he knows what doesn't. Whether big moose, bears, elk, anything else with a heartbeat or distant steel targets. The 7 NMI delivers!
