Re: Case exploded today !!!
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Tony.</div><div class="ubbcode-body">Not to hijack this thread, but per my previous post, I had the same thing happen as shooter65. Get this, same day, same ammo, same city, different range. I was even going to post a thread about this, then I saw this post.
I ended up a little bloody from the powder, but most importantly my eyeballs are fine. Thanks to the Oakley's I was wearing.
Here is the ammo I was shooting. I cannot remember when or where I bought it, since I have owned it for about 4 years.
I was shooting my new Remington 700 SPS tactical, I had less than 100 rounds through it (1 month old).
I started out shooting some shitty HSM ammo. Look at the primers on these.
I then switched to the 3D ammo / Hornady ammo. Again look at the primers
Here is a picture of the case failure. I also shot 2 more test rounds after (I know, I know....) Looks like I have some extractor damage.
I am not sure if I have a rifle problem, an ammo problem, or both. I will note that as the day went on, it became harder and harder to close the bolt. I really had to work to close it before the kB. The spent primers concern me and leads me to believe that the rifle is partially to blame (same problem, different ammo). I was also getting some light primer strikes on the HSM, I did not shoot enough of the 3D stuff to see if the same problem persisted.
The case failure is clearly an ammo problem.
Thoughts? BTW, Remington is sending me a prepaid call tag to ship my rifle back to them. </div></div>
I say you need to to a look at the fit between the firing pin and the hole for the FP in the boltface. Looks to me like you may have an over-sized hole which can lead to cratering like you see in the pics. Are you getting any other pressure signs? If you are getting ignition problems or the like, you may want to think about getting your FP bushed.
Agreed that the failure is a separate problem.
