At ARIZONA AMMUNITION, LLC.® we pride ourselves in making extremely precise and consistent  PROOF RIFLE ammunition for manufacturers.  We are not cheap! We custom make this PROOF rifle ammunition to the exact specifications for each manufacturer.  The industry standard is generally to be up to 15 to 30% over the listed SAAMI maximum of a specific rifle cartridge and caliber.  But, we have found that each loading manual , each manufacturer of bullets, or gun powder manufacturer can vary on a stated recommended maximum. Some manufacturers like to push their equipment beyond the SAAMI specifications too. We will build the PROOF ammunition to your specifications (if safe).

We offer custom loaded PROOF rifle ammunition to manufacturers that is precisely made. It is individually hand weighed for consistency as generated by our computer.  We offer them in lots of 5 rounds each or more up to 500.  You can not get more precise PROOF rifle ammunition any where!


To purchase our custom PROOF rifle ammunition you must provide the following;

1. Copy of your Federal Firearms License

2. Copy of your Manufacturers/Gunsmith License

3. Copy of your State Sales Tax License

You can FAX, Email, or mail them to us for our records.

Arizona Ammunition, LLC® has been building computer estimated rifle PROOF rounds for 15 years or longer.  PROOF rifle rounds are the pressure (psi) rounds fired once in a new rifle to insure its safety on the barrel and action.  Again rifle high pressure (psi) PROOF rounds are generally 15% higher than standard rifle rounds as described  the industry standard pressure (psi) setting organization SAMMI.  SAMMI sets these standard for the industry to follow voluntarily.

Arizona Ammunition, LLC.® uses a computerized estimate for rifle PROOF to determine the psi required to properly test a specific caliber and cartridge. We use a complex and exacting computer system to make the determination of components for the proper psi for each caliber and cartridge. In the the future will be adding PROOF rounds based on OEHLER “crusher” testing determination.  While we are very comfortable with the computer estimated system we are always looking for a better way or offering different testing procedures.

 We offer custom “function” rounds too for semi-auto and full automatic firearms.  These are LOWER psi pressure than PROOF rounds.

Computer estimated rifle PROOF rounds are only sold to qualified gunsmiths and firearms manufacturers.  Proof of qualification will be required.  We do not take orders over 500 computer estimated PROOF rounds at a time.  There are other fine companies like Hornady and Black Hills Ammunition for the larger PROOF round orders. We have worked with both for many many years with great success.

We follow SAMMI procedures in the construction of the loaded computer estimated rifle PROOF rounds to the best of our ability and the availability of the components. In some cases the components may not be available for our use and substitutions are used with customer approval (the cost may be higher too).  Each computer estimated PROOF round is loaded in new brass cases, we use modern very consistant and stable gun power, high quality primers, and each computer estimated PROOF round is individually handed weighed, bullet is hand seated, brass case is marked as a PROOF round,and is placed in a quality plastic box with warning notices on the box that it is holding PROOF rounds. THSI COMPUTER ESTIMATED RIFLE PROFF AMMUNITION IS DANGERIOUS!!!

TIMING- We know that rifle PROOF rounds are needed before a new rifle is shipped to the customer so we do our best to fit the order into our system.  We try to give PROOF round orders some priority to help the manufacturer out in delivering the rifle AS QUICKLY AS POSSIBLE.  There is no guarantee that the order will totally receive priority though.  Please remember our policy of “lack of planning on your part does not make it an emergency on our part.”  Please plan ahead on ordering our computer estimated rifle PROOF rounds.
