Reseating bullets

[Okdeerman]

I posted a thread about dimpling in my 6.5-06. I received varied opinions on the cause. One suggestion was that the bullet was not seated deep enough in the case , which I felt was a possible culprit of the dimpling, so I simply put the remaining cartridges in that group in the die and seated them about 030 deeper and head to the range. THAT WAS A BIG MISTAKE!!!! The primer was nearly destroyed, the velocity was 200fps more, and the bolt was almost unmovable. I learned my lesson and luckily am still able to tell the story. I learned that I should work up the load with that seating depth. Just saying!!!!!

ALL of the rounds did that, or just one. I have done seating depth testing at .010" variations up to .070" or so from the starting one and not had that much increase in pressure. I have seen pressure changes, but not that drastic.

How far off the lands were the original loads?

.030" deeper and 200fps gain in velocity with way overpressure?

I doubt it was the extra .030". Even if you were hard compressed to start. If you were that hard compressed, I can't see seating an additional .030" without some indication. Bullet deformity, hard throw on the handle, major crunch, bullet backing back out, needing more thn .030" adjustment on the seater die...
Something else is amiss.

I could understand not wanting to shoot another one after seeing that, but curious if this was a one off that was waaaaay over charged and was in the mix.

I value my rifle to much to try another one. I already have half of them pulled and dumped. I am starting over just to be on the safe side. I am trying to decide if I should use the pulled bullets.

They were .002 off, almost touching.

I went back and read the first thread. According to that, your load is way above what hodgdon has listed for max with IMR4350 and a 120 grain class bullet.
Max by them is 47 grains.

...and there's that

Is there a chance you turned the seating stem out instead of in, and ended up with .028" jamb?

 

[Okdeerman]

I don't think so, I mic'd the cartridge after I adjusted the die.

Ya, there's no way the seating depth change was the cause of that.

Depending on where you are on charge range, seating deeper w/o adjusting charge can be a catastrophe.

Like as in, if you were already way over charged seating the bullet deeper isn't going to fix that.

If that's thecase already, then no it isn't going to help like you stated.
