| I just picked up a case for $400 shipped. If you have never tried this ammo then you are missing out. For 1:9 shooters you may not like it but anything faster and it is very good stuff. I shot Hornady TAP (silver case) 75's and I honestly couldn't tell the difference between the 2. It has the slight ammonia smell but it isn't as dirty as some other US made ammo. I shot it against hand loads and it was .25 to.50 inch difference depending on the shooter. This is very very good ammo and MATCH quality is no problem. I didn't check velocity just in case somone is wondering |

I will carry a higher BC to the target so I would say yes it would be good for either hunting or self defense. I'm not sure if you could go any higher that 75 or 77 grain and still get them in the magazine. I know 80's won't IIRC, this can be found be readin the ammo oracle. In a situation less than 150M the nod goes to XM193, beyond that distance M855 is preferred, again going from memory. |

I didn't check velocity just in case somone is wondering Great, so whats the group on the handloads? Telling me its a bit bigger group than your handloads...well, that really doesnt tell me anything now does it? If your handload is a 2" group then Prvi isnt all that great. If your handload is "one ragged hole" then you sir have the Holy Grail of Prvi. I get around 1.5" groups edge to edge from a 22" 1-8 with a 5 shot group. Then again I only tested 1 day and it was running a 10 to 20 mph wind AND I wasnt at my best shooting either. I suspect on a good day and better form on my part I can get around 1" at 100 yards. The 69 grain Prvi seemed to perform a touch better than the 75's that day. |
Prvi Partizan 75 grain OTM
Thanks to the efforts of the esteemed Dr. G.K. Roberts, we now have some excellent information on the terminal ballistic properties of the Prvi Partizan 75 grain OTM load. Privi Partizan 75 gr OTM Velocity: 2468 fps from a 16" 1:7” twist barrel penetration in bare ballistic gel: 12.6" neck length: 0.8” maximum temporary cavity: 3.2” at a depth of 4.7” recovered diameter: 0.36” recovered length: 0.15” recovered weight: 30.1gr percentage of fragmentation: 60% The same lot of Prvi Partizan 75 grain OTM ammunition that Dr. Roberts used in testing had a nearly identical velocity when I chronographed it from a 16" Colt barrel.

100 Yard Accuracy Evaluation of Prvi Partizan 75 grain Match Ammunition.
The Prvi Partizan 75 grain match ammunition uses an open-tip-match bullet very similar in configuration to Hornady’s 75 grain BTHP bullet used in Hornady’s TAP line of ammunition and in Black Hills’ 75 grain MHP line of ammunition. The Prvi Partizan (PPU) bullet has a nominal length that runs approximately 0.010” – 0.015” shorter than the Hornady bullet. The PPU 75 grain bullet does not have a cannelure, but the case mouth on this load does have a slight collet crimp on it which puts a slight crease in the bullet. 
The PPU 75 grain match load uses Boxer primed brass cases and is charged with “ball” powder. Neither the primer nor the case mouth have sealant and the primer is not crimped. Previous chronographing of this load through multiple barrel lengths shows it to run an average of 127 fps slower than the Black Hills 75 grain MHP load. 
I have read some statements recently that claim the PPU 75 grain bullet was designed to shoot well through 1:9” twist barrels, yet none of those making these statements have provided any scientific evidence to support this claim. According to the Greenhill formula, the optimal twist for the PPU 75 grain bullet is 1:7.6”. From a 1:9” twist barrel, the PPU 75 grain match bullet has a gyroscopic stability factor (GSF) of less than 1.25 for all velocities. It is generally accepted that a rifle bullet should have a GSF of 1.5 to 2, with 1.25 being the least acceptable GSF. Gyroscopc stability factor from a 1:9" twist barrel. 
Gyroscopic stability factor from a 1:7.7" twist barrel. 
The test-vehicle for this evaluation was an AR-15 with a 24” stainless-steel Kreiger VarMatch barrel, with a 1:7.7” twist, installed on a LaRue Tactical Stealth upper receiver. A Leupold Competition Series Scope was used for sighting. No malfunctions of any kind were experienced during testing. 
Following my usual protocol for accuracy evaluation, shooting was done from a bench-rest at 100 yards. Three 10-shot groups were obtained using the PPU 75 grain match load. Those three groups had extreme spreads that measured: 0.66” 0.92” 1.14” for an average extreme spread of 0.91”. The best 10-shot group from 100 yards. 
The three groups from above were overlayd on each other using RSI Shooting Lab to obtain a 30-shot composite group. The mean radius of this composite group was 0.29”. For comparison, this composite group is pictured below next to a composite group of the Black Hills 75 grain red box MHP load as well as a composite group of one of my handloads. 
Here is a repost of some of the chronograph data for the Prvi Partizan 75 grain Match load.

Prvi Partizan 75 grain Match; Velocity Update
Here's a little update on the velocity aspect of the PPU 75 grain Match load. One can't help but wonder if Prvi Partizan has been listening to its customers. About the only complaint anyone has had with this load is that it has a lower muzzle velocity than the Hornady or Black Hills 75 grain loads. I recently chronographed the latest lot of the PPU 75 grain Match load that I have on hand and from a 20" Colt A2 barrel it is running approximately 117 fps faster than the original lots of this ammo that I chronographed!

Wow excellent work! Any word on the 69 grain PPU Match?
What about the .308? They have that in 168 and 175's. My 700 SS 5R LOVES the stuff (likes it even more than it likes the 173 grain 118LR I bought at the low low price of "a lot"). I'd love to see the same tests on it. |
| Molon, do you have pics of the gel testing from that round? I've been looking for pics of gel tests for heavy, non-cannelured OTM's like the Prvi and the Hornady T1's, to see if there's any significant difference between the fragmentation of those and their cannelured cousins. |

I'm not sure if you could go any higher that 75 or 77 grain and still get them in the magazine. I know 80's won't PRI magazines allow you load to COL of 2.30", and you "might" get some 80's in there... |
| Well Mr. Specop-007. If you have tried the PRVI then you know how good it is. You are right about the 69's grouping a little better. They were not MY handloads so I'm not sure of power, primers and so forth. For the money and for me they seem to be the best. I won't buy Black Hills, Hornady or any other brand that approaches $1 a round when this ammo shoots as good for me. I have acheived just over 1/2" groups @ 100 and 1" groups @ 200 w/ little wind and my semi decent shooting for the day. If you can find it then buy it. Good luck hunting |

I just like to get a rough idea of how it performs for others. I'm not unhappy with it but if I cant get my group down a bit I wont use it for much. Then again as stated the day i went out was just bad all around. windy, wobbly bench and I just wasnt "there" like I should have been. |

I just picked up 2k from palmetto armory for 455.00 per k. They are dated 0907 so I'm guessing 2009 July. Just got them this eve so I don't have any results yet really like the privi 55g SP though,so I'm figuring these will be good too. That should be correct from what I have heard about PRVIs date coding |

So you're saying, it was windy, wobbly bench,and you werent shooting well that day. And 1.25" ctc groups arent good enough. What are you using this particular rifle for . I will say all of my AR's shoot best with 69 gr. Sierra's. |

I will say all of my AR's shoot best with 69 gr. Sierra's. It was built as a precision AR. 22" Krieger, JP Precision trigger etc etc. I've shot around 1/3" to 1/2" groups at 100 so I know the rifle has it. Its a matter of the shooter and the ammo. More the shooter I think, I'm not a very good precision shooter and I can admit that. Hearing what others get from Prvi is important because it helps establish a baseline as to what the ammo can do. The question is of course can I get it to do that. As of now no but there were more than a few hurdles to overcome that day. |

If you can shoot .33-.50" groups I consider you a very good shot. I have 1 gun that will shoot .35" groups consistantly. A Savage 110 V. And it's more the gun than me. I would wait for a better day to test the 75's. If you want better than .33" groups I would look to the Benchrest crowd. Thinking Stolle action and a very good barrel. |
| Yes it will shoot 1/2" @ 100 and 1" @ 200. That is from sang bags, and when I'm really watching myself from the Versapod. The gun and ammo are far better than I am. If I find someone @ the range who has a rest where the gun is strapped down and they use an air trigger then I will know exactly what it is capable of. I had Fiocchi 62 FMJ and they shot fine for plinking but I wanted a nail driver and I'm satisfied w/ the gun and ammo and optic. |
