I use military brass in my PTR91. I have reloaded the brass up to four times. Commercial brass is thinner than military brass and I would not recommend using in the PTR. The flutes and the ejection are rough on the military brass (dents and dings) but after resizing and tumbling the brass using steel pins in the reloading process takes care of that. The part that is not mentioned here that is very noteworthy is that the rifle can eject the brass as far away as twenty yards! I can never find all my brass even at the range I use. But I have never had a jam or hiccup with my rifle, it is absolutely accurate and reliable. I can't say enough good things about the rifle.

The chamber flutes aid in extraction, the cartridge case is "floating" on the gases expelled when the round is fired

Good video. I just purchased a 1981 pre-ban HK91, and yeah I noticed the flutes on the brass as well as a dent too. As I did more study and research I found out this is normal. It gives me a better understanding of how a blowback rifle works. Your video helps a lot. By the way. Awesome rifle!

When using my ptr 91 FR, I began discovering mine does not shoot all types of 308 brass case ammo. Found out some casings have thinner walls and expand more in the flutes causing it to get stuck & jam. Found this out after looking at the ejected casings from the ones that cycled & the ones that didnt. The casings that failed to eject had huge grooves and the ones that did eject bearly had any (Indicating the casings expanded more). These 308 ammo that didnt eject were design for a completely different rifle concept than the delayed roller blow back system. To find the right ones you need to buy different brands, run them and find out which ones work and which ones dont. If they all work......lucky you. When i tried to shop around, i could never find info on how thick the casings are. Was kind of a pain in the ass try different ammo but i still love the rifle.

My theory is that it turns the last 20 25% of the case into a theoretical piston the roller action actually multiplies the movement for the one on the 308 accelerating the carrier therefore pulling the bolt head and case out of the chamber simple and simply genius to me it seems so on ungerman In Design unfortunately the great-grandson of the German storm rifle stg 44 55

The fluted chamber is hard on brass for sure... I find that around 40 percent of the casings I retrieve are too Damaged to reload, and the other 60 percent are salvageable for at least one reload before pitching, I'd be afraid to reload brass from this gun more than once. The benefit is that This gun will cycle any ammo you put in it, Brass, steel, Tar Sealed Surplus, any ammo you have.

Was lucky enough to shoot the original HK91 series in the early '80's. Even more fun was the Flemming HK51 conversion with the telescoping stock, barrel was chopped down to about 10" and to those who stood along side it were greeted with chest thumping concussion every time it was fired. Got real good with it I could fire from the hip( Chicago Style) and hit my targets out at 100 clicks. Too bad that was in the mid nineties and the price to buy that puppy was a good $25K plus the tax stamp, a bit too much for my lifestyle back then.

The SC-built PTR 91s must have a different relationship between all the assorted bits in the chamber than the Conn-built PTR91s. Because yours is the second SC-built PTR that is very nice to brass. My Conn-built PTR marks my Civvie brass a lot more than what you got there. I've reloaded the brass used in my Conn-built PTR91GI. It is possible. And I like the shot groups I get. Just a hair tighter than the Fusion 150gr and PPU 150 SP rounds that both my PTRs like About 2-3moa. Maybe the ridges embossed in the brass by the chamber flutes as the case is fired make the reloaded cartridges fit the chamber tighter. I use Federal brass, cut to 2.012" (+/- .003"), capped with CCI LRPs, loaded with 40 or 41gr of IMR-3031, and topped with Hornady 150gr FMJBT. I Havent done anything with my SC-built PTR-fired brass.

Thank you for the support! I'm glad you are enjoying the videos. I only have 120 rounds through it so far, but no malfunctions. 100 of those rounds were dirty Tula and it has run just fine. I am new to the rifle and .308 caliber as well but I find it to be very comfortable to shoot. Everyone is different but the trigger feels good to me. It weighs almost ten pounds so it is a beast compared to an AR or AK. My girl loves shooting it from the bench so if she can handle the recoil then any grown man should be able to as well. I hope that helps. Thanks for stopping by!

@jeremiahburton901

Delta-77 I received a notification on this thread. So I might was well answer it as well. :) haha But between those two rifles I'd have say it depends on the use. I haven't been able to shoot either but have been able to handle both a fair amount. Will be able to shoot the ptr soon (friend got the rifle previously discussed! Sweet gun, rough but rugged) The fal is obviously alot smoother but the g3 feels more solid. For a basic issue battle rifle for targets 200 yards and in with irons I would say the fal. The trigger is a bit better as well. It is a little faster but the basic sights are lacking refinement and adjustability. Wouldn't feed it steel though which kinda sucks when you want to shoot .308 a lot. But the g3 is a much different story. The ability to shoot just about anything through it is VERY appealing. Plus it seems to have a more refined sight picture to me, plus the ability to range out in increments is a useful feature the fal lacks. The g3 to me is a better option if you just want a battle rifle to blast with at the range that you don't plan on doing much to. I do own a m1a and have fired about 750 rounds through it. All brass, you can use steel at your own risk like the fal but brass is preferred. With the m1a vs the other two it has the best sights IMO (1 moa adjustments), best trigger, and the smoothest system (it feels like glass). Although the fal is a close second on being smooth to operate. Not one malfunction out of all 750 rounds except for 3 that were strictly magazine related. (cheap mag) I will say that rifle lends itself much better to the dmr role as it can be and typically is very accurate. But the other two seem to be better all around battle rifle solutions to me, you can beat them around without killing your soul a little inside. :P A lot of g3 rifles can shoot exceptionally well with good loads. I am not too familiar with fal accuracy but have heard good things with hand loads. Any thoughts? :)

Question, what is the reason my g3 keeps ripping the casing apart? And I mean in half the extractor pulls out the back of casing but the front stays stuck in the barrel. That only happens with the 308 but not a 762. I've looked into a few different things but keep having the issue.

.308 is more powerful than the 7.62. So you get a more violent extraction. With thin commercial brass that can mean case ripping. Mine loves cheap steel case. Have you tried that?

The price seems to be going up. Not sure who has the best price currently. I bought mine 6 months ago from Atlantic Firearms for $899. They have it now with a Primary Arms micro dot included for $969. PTR started putting the steel trigger housing and paddle mag release on the G.I. models in early 2016. I would highly recommend that you make sure that is what you are getting. The paddle release makes a huge difference. They were using the "Navy" style polymer lower trigger housing but switched over to the steel. The only advantage of the polymer lower is that the grip is ambidextrous. The steel lower has a grip that is molded for the right hand only. I would go steel/paddle release unless you are a lefty. Make sure you are getting what you want. More videos coming soon.

@GeorgiaBoy1961

Yes, but just inspect each case to make sure it isn't so dented as to be unusable, and also clean/tumble them thoroughly to remove soot. The flute marks are largely pressed out in the full-length resizing die, which you are doing since the rifle is a semi-automatic. Do not use brass fired through a semiautomatic rifle - any semiautomatic - more than three times before discarding it. The toughest part about using brass fired in a PTR-91 or G3 is finding it - since the case is often ejected more than 25 yards away!

The fluting allows the chamber to more effectively grip the brass while the internal pressure is high. It has nothing to do with making extraction easier.
