RPR Ammo Test: CCI Standard vs. Aguila Standard

CCI Standard Velocity is a popular 40gr LRN 22LR ammo among my club’s bullseye pistol and precision rifle shooters for its consistency. Some shooters consider it almost as good as match-grade ammo. I wanted to test its performance against the cheaper Aguila Super Extra Standard Velocity.

Testing both at 100 yards with my factory Ruger Precision Rimfire Rifle (RPR) with a Discovery Optics LHD budget 8-32×56 FFP scope. Aguila edged CCI by small amount based on my measurements using Range Buddy on my phone. The difference is performance is smaller than the difference in price, Aguila Standard Velocity being 25%-50% cheaper than CCI Standard.

Aguila Super Extra vs. CCI Standard

I’ve been long planning a broad test of various budget 22LR ammo to see which groups best in my factory Ruger Precision Rimfire rifle. Aguila Super Extra is (as the latter’s name implies) the slower velocity brother of Super Extra High Velocity. So toois CCI Standard the slower brother of the more popular CCI Mini-Mags. Both of these rimfire ammo’s are 40grn lead round nose bullets with a wax coating.

In my 100 yard tests, I was surprised at how inconsistently Aguila grouped. A good 1/3 of the Aguila rounds were flyers from the main group. CCI, while not amazing, had far tighter groups and more holes touching or overlapping. CCI Standard set the standard. I look forward to testing other ammo brands to see if any group better.

Anarchy Outdoors Little Birtha RPR Knob

The Ruger Precision Rimfire (RPR) is an popular entry-level chassis rifle for PRS training or NRL22. At its heart it’s a Ruger American action, which many companies make upgrade parts to customize and upgrade. One of the easiest upgrades is the knob at the end of the bolt lever.

The factory knob is a simple plastic teardrop which is functional but forgettable. The knob simply unscrews off the lever. Anarchy Outdoors sent me their Little Birtha knob which is an all aluminum dumbell shaped knob available in a variety of colors. Anarchy Outdoors makes the Little and larger Big Birtha knob for other popular rifle makes like Remington and CZ.

Anarchy Outdoors Penguin Grip

Anarchy Outdoors sent me their Penguin Precision Grip. This grip was designed by a former US Army Ranger and law enforcement snipers. Unlike the AR-style factory grip of the Ruger Precision Rimfire (RPR), the Penguin has a vertical angle favored by precision shooters. This angle allows for a more ergonomic hand position when shooting prone or bench rested.

Moreover, the features a thumb rest and hand wrest to reduce grip fatigue and encourage more even trigger pull. The palm swell is skeletonized palm both reduce weight but I suspect to promote airflow to reduce palm sweating. Installation was similar to an AR but easier as there was no selector index pin to keep track of. It was a simple matter of unscrewing the base bolt with a long enough Allen key to reach the receiver base through the hollow grip.

Anarchy Outdoors Bolt Shroud

If you own a The Ruger Precision Rimfire (RPR), chances are you never gave the bolt shroud a second thought even though it’s been literally right under your nose. The bolt shroud is the metal cap that cover the butt end of the bolt and houses the mainspring and firing pin components.

Anarchy Outdoors makes a RPR bolt shroud in a variety of colors. I requested a red shroud to match the red Little Birtha knob they sent me to test out on my rifle. Installation was simple but took a little bit of time as does anything involving a spring under tension. It was a matter of knocking out the holding pin and then re-using the main spring in the factory shroud.
