Stuck case in 300 win

I bought a new rem 700. I started working up loads with imr 4350 and 4831. I've tried 180 nosler accubond and 168 ttsx Barnes. With all loads I've been experiencing stuck cases after just a couple grains over min load. I've never had something have this kind of pressure issues before. Also just a difference in a half grain shrinks my group from 1.5moa to .5 moa. The extra half grain also goes from no pressure what so ever to a stuck case. Any suggestions?

Can you post a picture of the case from the side, belted area, and the case head?

Re: Stuck case in 300 win

what type of brass are you using

norma have 2 different wights in brass for 300 win mag
the heavy are 270 grains
the light are 215 grains
loads for a nosler ballistic tip 150 grains are in
heavy min 71 grains norma mrp
max 74,8 grains mrp
light min are 75 grains mrp
max are 79,5 grains mrp
this is only an example taken out of normas reloading book

i always check that and never had a problem with loading for a 300 win
now i live i Europa and use mostly norma and wihtavuori powder
hope this helps you

Re: Stuck case in 300 win

Go to your local Ace Hardware store or similar and get a 0.250" brass rod. Will cost you maybe $8. Carefully insert it into the barrel. Mark it where it touches the muzzle. Then wrap that spot with one wrap of electrical tape.

Reseat the brass rod. Tap with plastic mallet or similar hard enough to dislodge the case.

Do not use a cleaning rod. It will simply bend.

Here's hoping you were interested in removing the stuck case. And not something else.

Re: Stuck case in 300 win

Your description has some of us confused. Is a case stuck in the firearm or are you having difficultly extracting the case? If you eventually get the case out it isn't stuck. If you are removing these "sticky" cases there can be evidence as to why they are not easily removed.

If bolt handle is hard to open I'd suggest pressure. Do you chronograph your loads? You could be over the pressure limits but be under max load data suggestions.

If bolt opens easily but won't go rearwards with difficulty I'd suggest a chamber with a enlarged area. The case is swelling to fit that larger dia area and resists rearward movement. It can happen due to a very high pressure round going off at some point, bulging the chamber just in front of the web area. It could have been done when it was chambered. All subsequent rounds fired, even low loads will have same problem in removal. A tell tale shiny area will show on case near web.

Please give us more details.

Re: Stuck case in 300 win

The stuck cases have a shiney spot just in front of the belt. The bolt lifts normal it just won't come back. I have my bullet seated .020 off the lands. I have had the same problem with nosler bullets as I have Barnes. I'm getting this pressure with 68.5 gr of 4350 and 68 gr of 4831. I can back it off a grain and the case doesn't stick but the groups are big. Add a grain I get 1/2 moa but every other case will stick. I'm wondering if I have a chamber defect. I've been loading for 4 yrs with no problems. I'm new to the magnums and Barnes bullets though.

Re: Stuck case in 300 win

A friend of mine had the same problem with a 7 STW. He carried to a gunsmith who polished the chamber and it completely fixed the problem. He said that there was some type of imperfection in the chamber that when the brass swelled during firing caused it to stick. He did this while he waited.
