Anyone here have the Ruger Precision in 223?
How's the accuracy with 55g pills? Why AI mags! And not standard AR15 mags!!!! |

Why AI mags! And not standard AR15 mags!!!! Because it's a precision rifle and not a bolt action AR. The 7 twist barrel is made to use the heavier long range bullets which you won't be able to load into AR mags. The AICS style mags allow a longer OAL to about 2.550". It's actually a smart move. |

If you are talking about 55 grain FMJ bullets/ammo, I wouldn't expect a whole lot. They are a cheaply made and very inconsistent compared to a match bullet. My precision 223 rifle will usually put 3 or 4 into one MOA and then get a flyer. The other thing about this bullet is it has a very low BC which makes it susceptible to the slightest amount of wind change. |

I have a RPR 5.56. The only 55gr bullets I've tried are Sierra 55gr Blitz King. (I had worked up an accuracy load for an AR with them, so I tried the same load in the RPR.) 26.0gr WW748, RP brass, CCI #41 primers, 2.26" oal gave 5 shot 100yd groups in the .6" range. 3033fps average at the muzzle of the RPR. May switch to this bullet and load when I've used up my 77gr SMK's. With my mild cataracts, I don't see (pun intended) how I could shoot smaller groups at this time.
Since I have a quantity of pulled Sierra 77gr Match Kings, those are what I used to work up a load with and for shooting steel with, as they give a louder clang than lighter bullets. In my opinion, I'm not a great shot, but am "OK". 23.5gr WW748, RP brass, CCI #41 primers, 2.35" oal gave 5 shot 100yd groups in the .7" range. 2596fps average at the muzzle of the RPR. Why 2.35" oal? If the length was greater the bullets would need some force to close the bolt, and I'd have failures to chamber with the bullet tip catching on the edge of the chamber when fed from the magazine. At 2.35" if the round is pulled out unfired, you can sometimes see some very light marks from the beginning of the rifling touching the bullet. The Ruger mags can handle up to 2.55" length cartridges. Also tried some of my AR hunting rounds with the Sierra 65gr Game King...they gave around 1" at 100yd. Again, it was a load already worked up for 2 5.56 rifles I use in deer hunting. 75gr Hornady bullet (pulled) reloads gave 1 1/4" to 2" groups at 100yd. I don't have a lot of those pulls, so I gave up on them for the RPR (2 powders with 6 different charges were tried...I suppose it could be the pulled bullets as they had pull marks whereas the 77gr Sierra pulls didn't). My steel shooting consists of simply having fun ringing steel plates out to 300yd (the length of my range). No failures with the RPR 5.56 in 249rds fired (other than the chambering issue with too long of length mentioned above). Trigger left as-is from the factory (not weighed, but estimated in the 2 pound range). Muzzle brake was on slightly crooked; easily corrected. Have not tested it with a suppressor yet to see if the accuracy improves, stays the same or decreases. I monitor throat wear in my rifles. After 249rds, the throat has only advanced about .017", and that was only in the first 5 shots fired during break-in; no further wear seen. I don't let the bbl get very hot (a fan is on the bench blowing on the bbl), so I think my bbl is gonna last a long long time. The Ruger RPR bbls are 4140 steel, CHF, no chrome lining or nitriding. My .308 RPR shoots more accurately with my Ark30 suppressor mounted (about a quarter inch less at 100yd) than without. The .308 with the load it likes best consistently shoots .625" at 100yd; with the 2nd best load it shoots .64" at 100yd. The .308 throat has worn .05" in 369rds. Both are a joy for me to shoot. Hope this post helps some. |

Friend of mine has one. He is seeing .5 MOA or slightly larger with varget and 80grain ELD. Obviously loaded much longer than will fit in an AR mag.
I shot it with some 55grain geco and it was sub-MOA. What velocities are you guys seeing out of these? The Geco .223 velocities were in the 3150 range which is slightly faster than expected. My 18" AR only shot them 2950-3000. However 24.0 grains of varget under a 80 ELD is only pushing it 2600 or so. |

I worked up some 80elds for my 18"AR, maxed out at 2850fps(26.4g W748). These were loaded 2.620" oal at .008" off the lands.
There seemed to be a small node around 2775fps(25.8g W748) but it wasn't so when I tried again. Didn't look to promising from 2700 on up out of my rifle. I may revisit these again but they need to be around 2725 or more to be better than my 90smk load. |

I thought the same thing before someone called me out on the OAL issue and what people are saying is spot on. AR mags would be WAY too short for the heavy bullets. I've got a Remington 700 with a 1 in 12 twist that will shoot the 55 grain stuff just fine. I picked up this rifle to shoot the heavies. If you are only going to shoot 55 grain stuff, or MIL-Surp ammo, I wouldn't recommend this rifle. I shot 5 rounds of federal AE223 and it was by far the best shooting "blasting ammo". It shot 5 shot groups at about 0.75". As Lennyo said, we shot some Geico ammo out of it and it also shot sub MOA, I can't recall the exact group size though. It shot CG M193 and Wolf Gold at about 1.5"-1.75" groups at 100 yds. But again, I didn't get this rifle to shoot blasting ammo. It does really well with 75 grain Hornady Match and 80 grain ELD's. My accuracy load so far is 24.0 grains of Varget pushing the 80 grain ELD at 2610 ft/sec using lapua brass and CCI BR primers. I'm getting 0.5 MOA groups with it. |

My overall impressions of this rifle is that I'm very happy with it. My trigger wasn't the best. It actually felt like a mil-spec AR trigger honestly. I'm a Savage guy so I don't mind the trigger blade, but the creep was noticeable and rough. Lennyo gave me his factory trigger from his 6.5 RPR and it was much better than what came on my 556. Like most people are reporting, the brake is canted on the barrel. But I plan on taking it off and replacing it with a Silencerco mount for my Omega so that doesn't bother me at all. I polished the bolt as it was a little rough at first, that smoothened things up a bit. The rifle will also crater primers on higher pressure rounds. I had significant cratering on all the M193 ammo I shot. I'm not piercing primers, but it is something to note.
For the price point, I think this rifle has an unbelievable amount of value. For all those who knock CH Forged barrels, it seems to me that Ruger can knock out a pretty good forged barrel. I have shot a 0.183" 3 shot group with this rifle during load development, but I don't count it as only being 3 shots. I honestly don't think I can shoot that well consistently, but I can do 0.5" pretty consistently and this rifle will do it. I averaged 0.58MOA during the 80 grain ELD loads over 1.25 grains of Varget shooting 3 shot groups during load development. The rifle can definitely shoot. I threw an Athlong Argos 6-24x50 scope on it and am overall really happy with the set up. |

To add to my above post:
I reviewed my RPR targets. Had 1 5 shot group of .445" with the Sierra 55gr Blitz Kings (plain, not moly coated) at 100yd. Also had nearly 100% primer cratering (but primer edges were still rounded and no pierced primers) when testing loads with IMR4895 powder and virtually no cratering when using WW748. My Robinson Arms XCR-L's also give cratering due to their beveled firing pin hole (deliberate design on the factory's part), so I'm not worried. Even 50gr pulled frangible bullet reloads were giving about 1" at 100yd for 5 shots and about 1 1/4" for 10 shots, which I find amazing. The frangible loads are normally used for short range steel via my 5.56 SBR's and were giving about 1 1/2" 100yd 5 shot groups with other rifles. All groups are measured center to center. Brass doesn't seem to stretch as much as when fired in an AR. For example, I just resized about 80 RP cases fired in the RPR; only 3 needed trimming. The time to buy more magazines is when you warrantee register your new PRP with Ruger...they give you a code good for 20% off your next online purchases. 20% off brings the mag price down to $32. Yes, I will readily admit I'm liking the RPR. |

The only primers I've blanked in my 5.56 RPR are two rounds of IMI Razor Core 5.56 77gr.
I've gotten 80gr Amax @ 2.45" over 24.9gr Varget, CCI-450, Lapua brass to shoot half-MOA or better 5-shot groups multiple times with mine...only slight cratering with this load, never a pierced primer. I had trouble with the Magnetospeed V2 on the barrel with my bipod (really need the plug to be 90 degrees vs. straight) so I'm uncertain as to velocity. Bolt manipulation is very fast, and while I initially thought the trigger was great I have noticed a bit of the creep others have mentioned. I treat it like a two-stage AR trigger and haven't had issues. This is my first chassis rifle so I'm still figuring out how to be comfortable behind the rifle; I've had a number of accurate groups but seem to get horizontal stringing when I know is me and not the system itself. Ruger-branded 223 magazines are <$30 online, feed perfectly, and are shorter than out-of-production polymer AI 223 magazines. I'm pretty happy with it so far... |

I have fired mine just a few times. I like it a lot and it shows promise, and as soon as I can I will develop some loads for it using the long bullets. I thought Ruger quit making them now? Are they starting again? |

They aren't listed. Ruger did a good job on them, but I think the market really pissed the point of it. If that was the price point and style of 223 I wanted it was set up about perfectly. Quoted:
