The weather finally broke and things are drying out up here so I brought my “project” gun (P.O.F. P308 16” Recon model) to the range hoping for a few minutes at the end of training to get some rounds through it.

After 10 rounds to break in the barrel (seems like it takes forever sometimes to shoot-clean-shoot-clean . . .) I had just enough time left to zero it up.

Went out to 100 yards rolled out the mat, loaded 10 rounds of Black Hills 175 grain BTHP and went prone off of the bipod. I had high hopes of decent accuracy but really didn’t know what to expect, I’ve heard all the chatter dismissing the accuracy potential of a semi auto and this was my first experience shooting a “precision” semi auto gun.

My partner did a sweet job of bore sighting and the first round impacted at 8 o’clock. Made elevation adjustment and round two impacted at 10 o’clock. Made final elevation and first windage adjustment, third struck too far right at two o’clock. Came back left and rounds 4-10 gave me my final group at .75 moa. I’m no skilled shooter but am very happy with the accuracy of my semi auto piston gun. There was a gusting 5-7mph tail wind pushing the target stand around a bit so I might be able to tighten this up just a bit.

Anyway, I’m starting to believe that at intermediate ranges, the right semi auto gun will perform as well as a decent bolt gun. Can’t wait for some more time on it and to get it out to 500 !!!!

Re: P308 Range Report

Good to see your POF is shooting well for you. I am planning on making a semi-precision .308 out of my AR-10, and if you look around on here you can find plenty of accurate semi-auto rifles.

Re: P308 Range Report

Your rifle (and the performance you are getting) are almost identical to my 20" P-308! I couldn't be more pleased with my setup. As long as you do your part, the rifle will hold sub-MOA accuracy at extended ranges.

Good luck and keep up the good work!!

Re: P308 Range Report

I am extremely pleased with the accuracy of my new POF also.

I did this with my POF .308 16" yesterday, shooting this in Houston at a range of <span style="font-weight: bold">300yds</span>.(I had one other target with a better group, but this was the only clean target.

Shot prone, rear bag and bipod.

Re: P308 Range Report

I got my P308 14.5 in, sadly I'm stationed over seas. I had my father test fire it for me, seemed to have a problem ejecting, but POF was great about helping, sending it in and should be back in a week better than new. When I get home I'll send my range report and pictures of it. Can't wait!

(Also can anyone give the the MRR overall length please?) Thanks!

Re: P308 Range Report

that is one decent group!

congrats to the other postings as well. When I have more then a day off I will get to the range and post a pic or two.

Re: P308 Range Report

nice group, I hope that I can do half as good as that seeing how this is also my first semi auto build. Hopefully I will have a range report here in a couple of weeks, I have been dying to see what this Noveske barrel can do.

Re: P308 Range Report

That set up you've made is truly nifty. A bit glossy (glare) but the mechanics look superb.

I've always been a bolt shooter all my life (except for .22's) but am learning from a friend who just bought an S&W MP15 in 5.56 and is also transitioning from bolt to SA.

He's been studying up on Piston vs Stock gas tube and I've been doing the same.

We've compared notes and it seems that the piston design is inherently superior to the standard non-piston desing: in keeping everything cleaner, smoother running, which of course, allows for greater accuracy.

You can tell from my use of nomenclature that I'm still struggling to make my way UP to becoming a Noob, but that's half the fun!

Right now I can't afford to buy an ailing Meow a cup of moo, but I hope to be able to secure employment from some unwitting individual/company, willing to hire cripples and my hope is to have a quality AR10 Platform Piston Rifle in .300 SAUM (.260 Rem. is my secondary caliber-Accuracy Arms in Aurora) or .300 RUM (RND Edge Rifles in Longmont, CO).

Should some of you gentlemen not mind, allow me to put forth what's in my noggin on Build, and feel free to comment as the desire takes you....or not if that is your inclination.

Long Range Paper/Long Range Hunting Dual Use

AR10/Custom Platforms (Accuracy in Aurora/RND-Edge in Longmont)
30"-32" bull barrel (SS but Titanium would be better-really bad back), Free Float 3 Rail/4 Rail
.300 SAUM/.300 RUM (.260 Rem. as a secondary choice)
Piston System
Muzzle Break
Flip Up Front and Rear Sights (in case of optics failure)
Upgraded internals including Two-Pos. Trigger, 2.5lbs Final
MagPul Adj. Stock
Heavy Pistol Target Grip
Bipod (which type best, I've nary a clue for the AR)


The optics I'll be using will be my Leupold Vari-X III 8.5x25x50mm/30mm tube. Premier Mil-Dot Reticle (the one that the old man was selling before he passed away) with round mils and half-mil hash marks.

I was forced to sell my Rem. 700BDL in .338 RUM for financial reasons, but kept my Leupold with the Premier Reticle....still haven't seen a reasonably priced long range scope with half-mil hash marks on the market.

Right now, I don't have a pot to piss in (as it were), but one can spend some quality time considering, learning, and gathering quality information, so that when the finances improve, I can utilize all that info into having a high quality build that is a shooter I can use for 'all occasions' at long range.

I'm also considering my secondary SA rifle, but for Brush Hunting/Close Range use, in the .50 Beowulf caliber. I looked at the Socom .458, but the reloading vagaries of the .458 Socom are greater than I care to enjoin on a regular (daily I hope) basis.

The Brush Gun would come from Accuracy, but in the Beowulf, they'll build it in either the AR Platform or the Mini-30 Platform. Do any of you gentlemen have any personal experiences with real world comparatives between the two Platforms?

I understand that as a stock item, the Mini-30's were unreliable barrel wise (and hence accuracy wise), but functioned properly and could be accurized for a reasonable amount of money. The people at Accuracy guarantee 1-MOA to 1.5 MOA depending on the models and upgrades used.

I'd consider building one myself from base components, but considering my severe lack of experience with SA platforms, I believe the opportunity for making too many wrong choices, and hence mis-spending money which I will not be able to afford mis-spending, would not be a good idea.

Bullet wise, I'm an SST Hornady fan, as well as Nosler Ballistic Tips (used them both in my .25-06 NEF and in my .338 RUM 700 Rem. BDL).

Sadly, only Stag seems to make left handed model uppers and I don't know if the folks at Accuracy will use parts from Stag (and I won't bother asking them until I have at least 50% of the necessary funds for one of their Builds, no need to waste their time).

Well, there's that kettle of fish......so if you've the time, the inclination, and the patience to deal with me and my inquiries, I will greatly appreciate it.

Thank you gentleman for your time and consideration.

Cheers from Wyoming.

Re: P308 Range Report

the 14.5" .308 is pretty darn accurate too.

From POFs website.

http://www.pof-usa.com/pdf_files/P-308ballistictestresults.pdf

the shorter barrels do pretty good at the 100 yard line compared to the longer barrels such as the 20inch.

If all your doing is 100 yard shooting go with the shorter barrels but if you ever want to get out to the longer ranges the 20inch will be a better choice.

Not saying that the shorter barrels are better then the longer barrels all around but there is a benefit to each.

Re: P308 Range Report

My P308 14.5 I plan to use for shooting from 100m to 700m (if able to keep the round stable, at super sonic, and enough energy behide it and on target at 700m, if not than move down to 600m or whatever I need to keep good 5 round groups in 7 inches and everything else) and also use it for reflex shooting, MOUT training and etc on my own time. I just don't believe the military gives you enough trigger time or MOUT training. Just waiting to get back to the my upper back and get back to the states, 34 days, yea!

You put that in a new thread, and you will probably get some answers.

Edit: My POFs shoot great too, I don't know why they aren't more popular.

Re: P308 Range Report

The P308s have had a few issues before, sometimes with ejecting, the trigger, the rail lining with the barrel or other little things, thats one reason some people aren't sure about POF yet. Also the time it takes to get a POF after you order one sometimes turns people away. My issue with my P308 POF was handled fast by POF and because of that and how unreal their rifles are 2 or 3 other people in my company are looking into getting a POF now. I have wanted one for awhile and can't wait to get back to test her out.

Now I just am wondering what is the length of the MRR rail on P308s and get some other info on P308 14.5 at the range.

Re: P308 Range Report

That is an awesome range report. I know I may hear it from some people but I will be brave and say it anyway. I should have gotten this rifle instead of my SASS. It looks really good and I have tried the 20" POF and should have just forked over the money to get the POF instead of my SASS.

Re: P308 Range Report

Fluted yes, thin no. The POF barrel is a very stiff unit that runs a balance of fast heat transfer (cooling) without giving up rigidity.

They only look thin next to large objects like NOMAD:

Re: P308 Range Report

haha yea, she makes that rifle seem to not be there hu

Ok now on a different point, I went to a range today, the rifle shot great, but I had a problem while trying to zero. When I was zeroing it was shooting low, I clicked it up but even when it was fully up it still shot just a little below the middle, anyone have any info that could help with this issue? It's a Leupold Mark 4 2.5-8x36 MR/T M2 Illum Reticule with a LaRue Tactical SPR QD mount 540-010-104. I'd think it was the mount wasn't the same height if it was a 2 pice mount, but it's a one piece. Any help I'd be greatful!

Scope defect maybe?

Re: P308 Range Report


The mount and ring height MAY be bringing line of sight too high over the bore -
dump the mount and sock scope rings directly to rail?
All else fails use process of elimination:
check to make sure ring screws are torqued properly.
make sure mount is installed properly - push it forward on the rail b4 securing it.
did you lap the rings.
check set-up on another rifle - see if you can get a consistent group.
What is condition of scope
If all checks out on the top move on to the gun - POF - doubtful but possible :)
Get shootin' ..........................

Re: P308 Range Report

You may need to shim the scope. If you all out of clicks and still short I would trim a peice of a plastic bottle or s coke can and place under the bottom of the scope on the rear mount and just see if that brings you up any. This is a fairly common thing to do on a scoped rifle.

Re: P308 Range Report

Thanks for all the help, i'm gonna go shoot her again tomorrow, it's something to do with the mount for sure the Leupold Mark 4 is unreal, and the rifle shoots great. It could be that I was trying to pre zero at 25 yards before. I moved the mount is it's more in the middle and I'm gonna zero her at 100m like I planned tomorrow, no pre 25y zeroing. I will zero the CCO at 25m though. I'll let you all know how it goes tomorrow. I have used a few LaRue mounts before and NEVER had an issue with one, so I think it's operator issues haha. We will see tomorrow

Re: P308 Range Report

Ok got the scope issue fixed, shoots amazing groups, I'll try to get some pictures of 100m range report soon.

I have another issue now though, when I pull the trigger I just get a click, when I look at the round it doesn't even look as the firing pin hits the primer, no mark. This rarely happens. I have seen a lot of stuff before but nothing like this. I have seen the firing pin hitting to light, but there is still a mark on the primer then. Like I said this rarely happens too, and happens with shi**y ammo like Wolf and also with good ammo like Hornday TAP. Now I did put a Enidine Hydraulic Recoil Buffer, also my Firing pin retaining pin is bent, it has been since the first time I went to shoot, but the rifle still works great and I plan to order a few new ones. I don't see how a bent firing pin retaining pin would do something like this, I don't really see how the Enidine Hydraulic Recoil Buffer would either. Please hook me up if you have any ideas, I'm out. Thanks for your time
