PTR 91 chewing up brass pretty bad?

[HPBrowningMK3]

Besides geting an HK ejection port buffer(out of stock everywhere, but I will find one eventually), is there anything else that can be done to alleviate this known problem with PTR 91s?

Use steel-cased ammunition so you're not tempted to reload? I don't know. I have a PTR-91 and a port buffer, and my brass comes out with dents and a series of pretty little grooves running along the side.

[HPBrowningMK3]

Yeah, that's some of my buds say too. So just I understand, the buffer doesn't really help?

[Yemff]

are you talking about grooves from the chamber flutes or dents from brass hitting the ejection port? if the latter the only thing you can do is get a port buffer or shell deflector. Learn to embrace the flutes.

are these problems on new ptr 91's? I am looking hard at getting one. but 7.62 nato is expensive. Im trying to do as much research as possible on them before committing.

where as ar15 5.56 nato not so much.

[kishigo]

Just to clarify. A port buffer helps, but you'll still get a few dented cases. And since the PTR is currently made more like a real HK91, the "flute grooves" are more apparent than they were before.

[kishigo]

Still a hoot to shoot though.

Yeah, its a new Ptr 91, I am talking about the dents from the ejection port. I've got some steel cased ammo to shoot until I get an HK buffer. Everyone seems to be out of stock?

Try Here, looks like they have them in stock...

Shell deflector is not going to help with the dented brass. A port buffer is more helpful as the buffer is a piece replaceable polyurethane rubber.

Here is one I was told to get (out of stock)

Anyone has any experience with it?

welcome to the world of shooting delayed blow back roller locked guns with fluted chambers. They destroy brass but that is the way it goes. I would not trip to hard because its a no no to reload casings shot out of those types of guns anyway. Very typical what you are experiencing.

[Cuda440]

Actually many people do reload cases from a fluted chamber, multiple times per case even. The main thing you want to look out for is the dent in the side of the case, use a port buffer to minimize that and reload away.

**if the port buffers are out of stock, shoot steel case till you get one. Ive shot a lot of this MFS ammo, its great stuff IMO http://www.sportsmansguide.com/net/c....aspx?a=891110

I reload PTR brass. I have the version with the top rail welded on so those port buffers won't work for me. I cut up a length of rubber band and glued it onto the back of the ejection port lip, it helps a lot to minimize dents.

Having fired/reloaded fluted/fired cases in a bolt gun many times I can say I have not had a case split lengthwise.

I can understand the possibility of having a case failure/split lengthwise in 4-5 reloading in a HK91/PTR fluted chambered rifle.

Its a military rifle where they don't reload so your stuck with an operational design different from other semi auto military rifles.

I don't own a ptr/hk91, only shot one once many years ago, Is there a way to reduce ejector spring tension (if it has an ejection spring/plunger) or reramp the fixed ejector(if it has a fixed ejector) face to redirect case deflect/crash with port/knob surfaces distorting cases?
