Title: 270 wsm Silver ballistic tip question
Post by: Weehunt66 on November 08, 2012, 08:18:43 PM: You can see the issue on the attached photo. hint.... the one on the right is correct. Here's what happened. after shooting a coyote ( 2 shots) my son unloaded - ejected the third round. ( it's the one on the left). I know they were in good condition when we started. I loaded the clip ( tikka T3 lite).
What caused the bullet to recess into the case?????

Not enough neck tension. The heavy magnum recoil moved the bullet in the case. You sometimes see something like this with heavy magnum handgun rounds.

Yeah... don't shoot it. Winchester might want to know about this too. Winchester either had an over-sized neck expander and/or did not crimp the bullet into place if it required a crimp.

If you had an inertia bullet puller, you could get that bullet seated back out to it's appropriate over all length and then shoot it, but to shoot it as is would probably blow up your rifle. Pay attention to the rest of the rounds in that box and lot if you have more. Shooting them one at a time with nothing in the magazine would be okay, but it's the recoil that is affecting the rounds in the magazine.

NO NO NO NO NO NO NO

While most rifle rounds aren't as sensitive as something like .40 S&W or similar high pressure handgun rounds, a bullet seated too deep raises pressures quite a bit. This is beyond excessive seating depth. I believe firing this round would result in a damaged rifle in a best case scenario. WSM rounds are already pushed to their high limits.

I'm going to respectfully disagree.

Post by: bobcat on November 08, 2012, 08:41:38 PM: Well, don't shoot it then. Just saying that is what I would do.

Post by: Fisherdave10 on November 08, 2012, 08:44:23 PM: To answer your question more precisely, when the rifle recoils and moves backwards, the round(s) in the magazine don't move with the gun instantly. When playing 'catch-up' during the recoil process, the tips of the bullet are smacked against the front of the magazine during recoil, similar to what would happen if you held one of the rounds in your hand, then smacked it into a table point first. Because there isn't enough neck tension to prevent bullet setback, the bullet slides deeper into the case. This isn't a normal thing for correctly produced ammo, but it will occur more often in magnum calibers and light weight rifles.

Probably would be best to use a bullet puller to get the bullet back out, and then you could shoot it.
