New rifle and problem

[bushwackr]

I got my new rem 700 stw. I loaded up a few rounds to try it out and all was well when I shot the first round and I went to extract the empty and it was stuck. I though crap what now, new rifle, new brass, medium load. I got it out shot another same thing bolt will lift but not extract well got it out. Now Im kinda worried, I used 74 grains of imr7828 ssc , new nosler brass, 215gm primer and 160 speer bullets. mid charge load, magnum primer, loaded to the oal of in speer book.

I unboxed the rifle and cleaned it good, I cleaned the chamber and barrel good so I know there wasnt excess oil in it. New brass loads great, the stuff i just shot is hard to chamber. Any Ideas

Might have to have your smith polish the chamber...

Also, 74gr of 7828 SSC doesn't sound like a medium load for a 160gr bullet...But Inalso don't load Speer bullets.

You sound like you have excess pressure, and if you have flattened primers you might wanna back the load way down and work your way up till you get slight pressure signs like sticky bolt or flattened primers.

Also, not every rifle will have the same max loads. Max load for one rifle might be a medium load for another.

How about a little more information?

Unmodified factory rifle?
Any marks on the fired cases?
When you say the bolt handle lifts easy after firing, does that include the last 1/4" of travel?
If you mic the diameter of the fired brass, does it taper from about an 1/8" in front of the belt all the way to the shoulder?
When you rechamber the fired brass is it difficult to remove?

for mudrunner2005 the manual calls for 72-76 gr of 7828. I went with 74gr and it just so happened that it was about -10deg f outside, thats why I am kinda baffled. This is the first time I have ever seen any issues with handloads , especially when the loads come from manuals.

orwapitihunter, the rifle if factory new ,2 rounds down it. the only mark I can see on the brass is there looks like tool marks on the shoulder of the case, rings around it. the bolt lifts all the way up, because all I had to do is bump the bolt back with an open hand and it opened up. When I mic a case it is .515 in front of the belt, shrinks to .490 right at the shoulder. yes when I try to rechamber the fired brass it is hard to close and to extract

Does anyone know what the capacity of the nosler brass is verses the remington brass

I found nosler 90.6 gr of water

Well I'm sure that it is not my reloads. I went and loaded up 2 rounds with diffrent powder lowest load show, first was 75gr h1000 case stuck, second was 66gr of H4831sc that case stuck also. So I assume its the rifle. I think im going to have to head to a smith.

Sounds like you don't have enough primary extraction.

Your smith needs to mic the chamber width-wise to see if the chmber is too fat. If it is, I'd be calling Remington asking for a new dang barrel blank, but that you want YOUR smith to install it and chamber it with his reamer.

Could just have some burrs in there and it needs polishing... Most factory chambers are a crap-shoot, because of how many they produce.

Ok thats a possibility, but would it cause a problem only after I fired a round. If i eject a loaded round its smooth as glass. just a fired round is an issue

It might just be a rough chamber I have rings all over on the shoulder and some on the case body on the fired brass

Ya I'm going to call them and see if they will send me a blank , or see if they have smith do it, he is a remington dealer so that might be what happens. If i have my choice I will have our smith install it

They probably won't sell you (him) a blank without it being chambered already. If they won't, you'll be better off having the smith true up the action, and have a custom barrel installed. It will be better than anything Remington will send you. Plus, it's a good excuse to build a custom 7mm STW with a 26"-28" heavy barrel.

If you don't want to spend much, just have the smith polish it out, hand-lap your barrel, true the action, headspace, and shoulder lug, and bed the action. That's a general accurizing package at most shops, and should make a noticeable difference, even with your factory barrel.

I just pulled the bolt and looked down the chamber on my custom 300 wm and then pulled the bolt and looked on the 7stw and there is a huge diffrence. the 7 has a very rough chamber ,i can see machine marks all the way to the neck. Not very pretty in there. My other rifle is just smooth inside

Yep, either they used a dull reamer, or they rammed it home, instead of letting it cut nice and smoothly like it's supposed to. A good polishing might be able to get those marks out without opening the chamber walls up too much. I'd have the smith snatch the barrel and send it back to Remington to show them just what kind of crap they're putting out.

Sounds about right for a factory Remington, unbox, fondle, send to gunsmith!
