Lose primer pockets

[kyron]

So just to make sure I get what you are say correct. The carbon around the primer pockets and the outside of the case necks would be fixed by making my load hotter?

Or by using a softer primer I could at least fix the carbon around the primer pocket?

And most likely the loose primer pocket (there was only one) is maybe just a bad case?

That loose one stayed in on its own. it just went in with almost no resistance.

I'll most likely look for some softer primers rather than bumping up the load and hope the accuracy stays where it is, because it seems pretty good right now.

Thank you.

I know it's been mentioned, but pressure definitely affects primer fit. I had two rounds out of some if my brass before the primers just fell back out during load testing when I was running up to the absolute max loads

The cratering you see around the outside edge of the primer is caused by the way new Remington bolts are made with a beveled firing pin hole.

And your enlarged primer pockets are caused by soft brass, with Federal and Remington being the softest.

Also the thickness of the flash hole web has a big effect on how much pressure the case can take before the primer pocket starts to expand. I have a scrap brass bucket half full of factory loaded once fired Federal .223 cases with over sized primer pockets.This was caused by soft brass and a thin flash hole web pictured below.

I use pin gauges to check for oversized primer pockets matched to the primers I'm using.

I use the Lee depriming tool to test seated primers, if the primer moves with just finger pressure the case goes in the scrap brass bucket.

Bottom line, do not load as hot or switch to a harder brand of brass.

Wow !!!
That is the first time I have ever seen a bolt with the firing pin hole chamfered. That doesn't even make sense that a manufacture would do that for any reason. The firing pin hole does not need to be chamfered because the firing pin comes in from the inside of the bolt and nothing ever needs to go in from the front. I am going to look at as many Remington's as possible to see if this is the norm. If it is, I will never use another new Remington action for a build.

Possibility, someone placed the bolt between centers and the live/dead center chamfered the firing pin hole.

Thanks for showing this to us. (Now I have to add one more thing to my check list).

My Remington 700s from the 1970 and 1980s do not have a beveled firing pin hole, but the one I bought 4 years ago does. If you Google the subject you will find it is standard now and Remington will not fix it. If it bothers you then you can pay to have it bushed.

Wow. I had to look at my bolt and firing pin. Don't know the manufacture date but I bought the rifle new last November.

That's more like it. Rough, but not beveled. I all ways square the bolt face to true it and make the firing pin hole edge clean and square so there is little or no primer cratering. Beveling the firing pin
hole, would be the worst thing anyone could do. Smiths will go to a lot of trouble to make the firing pin fit the hole from installing an oversized firing pin to bushing the hole. That's why I am having a hard time getting my head around why Remington would do something this bad on purpose.

I Hear and believe what you bought was that way, but I still think that was the exception not the rule. Beveling the firing pin hole is a fundamental Gun smithing mistake. I have a call in to Remington, to find out if this is the "New" way they are doing there bolts. I will post there answer
as soon as they respond.

Maybe some of the other smiths will chime in and let us know what they think about the bevel.

The only thing I can think of, is they had problems with burrs in the firing pin hole after mass-machining the bolt face, so they reamed the firing pin holes to de-burr the hole.
Only thing that I could possibly think of. ???????

Just a follow up of the chamfered firing pin hole.

I sent Remington Technical pictures of the bolt with the chamfered firing pin hole and ask for there comments.

This was there reply. Quote: Remington is not chamfering the firing pin holes on the 700 bolts. It would cause a variety of technical issues related to firing that would be detrimental to the rifles performance.

So someone has altered the bolt probably thinking it would be an improvement. Like many things, if you alter any part of a factory rifle, they will not fix it free of charge. In this case, the bolt should be replaced and the rifle re-head spaced so they would want/need you to send the entire rifle to them
for repair.

I thought it would be strange for Remington to do something like that, and that someone chamfered
the hole be it a factory worker or someone wanting to push bushing the hole. Who knows any more
why some people do some things.

Also I went to Academy and looked at all of the Remington 700s they had (Like I was looking to buy a rifle) and did not find a single bolt that was chamfered.

Just info on this issue.

Yes they are. This is a common Remmy problem. Too large of a FP channel and chamfer.

Horse ****, and you are totally wrong, I bought my Remington 700 new and it came from the factory with a beveled firing pin hole. These bolts with the beveled firing pin hole were made between 2008 and 2010 and "MANY" people complained about it.

I emailed Remington about it and they said not to worry about it it would not hurt anything and would not fix it. Now Google the subject, you will find even more photos and it was a topic at AccurateShooter and many other forums and to fix it you need to have to bush the bolt face.

At the link below it is being discussed and "now" Remington is replacing the bolts. Read posts 6 and 9, so it depends on who answers your complaints at Remington.

Wow there Bigedp51. Seems you are correct about Remington having beveled firing pin holes in the past. It seems well documented if you really search for it. But the horse **** comment is a bit over the top!

Starting with your first post on the subject in post 123, you do not say that this was something Remington did only from 2008-2010. You actually make it sound as though they are currently doing it. Your photo of one is also a stock photo from another site. In your second post on the topic you state that it is "standard now and Remington will not fix it! In your last post you call JE's comment horse $**** and that he is wrong and then go on to state that the bevel was only done from 2008-2010!

It is becoming clear how JE' statements have unfolded. I feel that JE was relaying EXACTLY what Remington told him about Remington not beveling the hole. I think the issue is that since they have not done it in 6 years, the tech JE was talking with had no idea that it was ever done!

I think JE has gone well out of his way to research this, even discussing with Remington, and wasted a lot of his time in the process. It would have been a lot better for all of us if you had been more informative about the 2008-2010 date in your first post and not had people chasing their tail.

Thanks for all the effort here, JE. Seems we have all learned something.

1. Its not a stock photo, I took the picture and other people posted it.
2. JE insinuated that I or someone else modified it and that is "Horse ****".
3. If JE had done some research he would not have said:

"So someone has altered the bolt probably thinking it would be an improvement. Like many things, if you alter any part of a factory rifle, they will not fix it free of charge."

4. Bottom line, my Remington 700 and many others have beveled firing pin holes and it was not done by Bubba the Shade Tree Gunsmith. And repeating what was told him on the phone doesn't mean Remington told him the truth. If you read the links I posted Remington has said many things and I repeated what they said. When I contacted Remington they said this was normal and they would not fix it. And judging from all the people who had their bolt bushed it appears I was not the only one who was told Remington would not fix the problem.

So yes I took his comments as a insult, my name isn't Bubba and I went to a lot of effort posting answers for "Lose primer pockets".

And since this is your first posting in this thread "YOU" didn't supply any information here at all. And now you want to grade my posts and say my photos are not mine.

So sorry Barrelnut you have brown eyes and are full of fecal debris. And I do not care if you and J E Customare forum buddies.

Have a nice day

 

[Barrelnut]

You cannot get around the fact that your first sentence is wrong and misleading in post 31. Your misinformation started the deterioration on this thread to what it has become. So all of your crude remarks are pointless.

JE is buddies with many many many forum members. He contributes much, He deserves respect. You were attacking him. I did not see his comments as attacking you. And if you keep telling people the are full of ****, I will talk to the Admin.
