nosler ammo question

[eastcoastguy]

I just switched to nosler accubond. After ther shot its hard to work the action.its very tight.is anyone having this issue  or know why its happening? Its never done it with any other ammo brands.

After the shot the bullet is gone so it is not the issue. The ammunition is loaded to slightly different specs. The cases have expanded and are tighter in the chamber. It is often a symptom of higher pressure. I assume factory ammo?

[eastcoastguy]

Yes factory ammo.  I know how is doing it just not why. The bolt is extremely hard to open after the shot. I've shot Hornady gxs with no problem and on paper it a little higher in specs. Could be just this box.

You're probably right. I bet it's just that batch. Getting a little higher pressure.

Sign of over-pressure.  What do your primers look like?  Throw up a pick. 

What rifle/round are you shooting and what year was it made?  I have seen over pressure more then a few times with factory ammo, usually in lever actions such as the model 88 or pump guns but have seen it in bolt guns too.

Certain factory loads do that in my 300 RUM.   Find a different ammo.

Federal Fusion did that in my Savage 300 wsm. Barnes or Federal Premium does not.

The best thing to do (if you shoot factory ammo) is to buy rounds from all the various manufacturers, Remington, Hornady, Winchester, Federal, etc.  Over a period of time, shoot them for accuracy at 100yds and find out which one wins.  When you find what works best in your rifle, buy a case of it (or more) especially if you can get the same lot.   

I have done this for a few rifles that I don't or don't want to reload for.  One of them, a 1960's Remington 700 7mm mag., loves Winchester Ballistic Silvertips so I shoot those, they clover leaf at a 100 yards prone off a bag.  I purchased all the boxes I could in the same lot and finally ran out a year or two ago.  I was worried that the lot difference would change the poi with a new lot but it didn't.  10+ years later and the poi is the same, irregardless of the lot.

It is expensive to do (now days) but well worth it.  I am now in the process of doing it with an LR-308 long-range setup.

The rds keyhole at 100yrds. The cases are my only issue.thought about buying 1 more box to see if its a fluke.my gun loves the bullet. I shot rem core lok an they shoot just as good  unless i jump up to a heavier bullet.i tryed hornedy gmx and couldnt get better than a 5inch group at 100. I just don't want to ruin anything.

[fastdam]

It has the potential to ruin your exctractor. I ruined one in a rem 700 testing hot handloads.

[eastcoastguy]

I'm using the rem 700 platform. More testing i guess.

[300rum]

If you are not getting primer flow or flattening I would stick with them because of the accuracy.  Is the bolt "sticky" or can you just not get it open without beating on it?   

[TVHunts]

It is likely they are a little hot but, here is another angle. 

Try thoroughly cleaning your chamber. If you don't have a chamber mop/cleaning kit make one out of a wood dowel. Under size the dowel to accept a thick cotton t shirt and scrub the heck out of it.  I was having this issue with an A-Bolt in 300 Win Mag using hand loads that were in no way hot loads and it solved the problem.  It's worth a try.

A picture of your primers would help. 

Good luck

The rds keyhole at 100yrds.

That would be enough for me to choose a different load.

[eastcoastguy]

I've tried to get a picture on here and it wont let me.ill try again when i get home. I just went tnrough the gun before i shot it so eveything was cleaned and lubed.i know its not that. I looked last night at hornady and it says they have a higher bc then nosler and no issue with the cases.might have to look for a different Rd but we shall see.oh and bob33 why would you choose a different ammo if its key holing at a 100yrds?
