Bullets and Moderator

[lookout]

I honestly think that her poor father was the last one to die,before Sheila.

It depends on the style of sound suppressor. In a wipe style sound suppressor the bullet rubs against things.  While they rub against soft material some have steel wool, metal mesh or something else as a filler that can potentially scratch the bullet.   

The moderator in question was a baffle style not a "wipe" style.  The bullet doesn't touch anything inside the suppressor so it will not leave any marks on the bullet.  Thus there is no way to prove or disprove whether a sound suppressor was used to fire a particular bullet by examining the bullet.  You have to look to other evidence to try to establish whether such was the case or not.

 I've just read that----------the same as you have !

I think there might be a slim chance though.

Slim chance of what?  The only way marks are left on a bullet is from the bullet being touched by something.  Rifling in a barrel touches a bullet hence why is leaves impressions.  When no shots are heard and thus a sound suppressor is suspected of being used they try to find out if a sound suppressor was available and if so whether the gun could accomodate such suppressor and assess based on such types of things.

There is a slim chance the moderator wasn´t aligned a 100% correctly, so there might have been a tiny skewness. The bullets might have touched the baffle plates slightly.

Try not talking to me as if I am an idiot!

There is such a thing as a 'baffle strike' but it damages the moderator quite severely.

[lookout]

With Sheila using the rifle,it would have been skewed alright--------and it was. The moderator was damaged as was the butt of the rifle through mishandling,as a rifle is a cumbersome firearm to use inside a property especially in the hands of a novice,one who is sick as well. It would have been pointing every which way with Sheila on the end of it screaming like a banshee.

Where does it indicate that the moderator was damaged?

I read some time ago that it was scratched. I would think Mike could bear me out on that one,though I'll see if I can find the article.

 Yes it's there from Mike------December last year,Ron Cooks' letter regarding the damaged silencer.

Oh OK, Yes, I know it was scratched but a baffle strike would damage the inside - a bit like this ......

The bullet is deflected instead of firing straight and will damage the baffle.  It could damage the entire channel or worse come out the side. The damage to the sound suppressor will reveal that such occurred.

There are times it will deflect out the side of the tube as well.

If you search damaged silencer,it will explain more in the letter which I gather was reluctantly submitted.
