Fired off a few rounds today in my Ruger SR45 and noticed the brass is getting nicked down at the bottom. Is this a big concern toward reloading these cases? Should I contact Ruger and see what they say??

No safety concern.

It's where the sharp edge of the extractor hook is digging in to yank the case out.

Ruger will tell you to go pound sand as long as it is extracting.
They don't condone reloading, and could care less what the once-fired brass looks like.
As long as it isn't still stuck in the chamber.

It night be from a but to much pressure. If not take a file & break the edge of your extractor.

No, pressure has nothing to do with it.

It's just a really sharp edge & strong spring on the extractor.

Yes, normal. No worries. Some guns do it worse than others.

Your fine. Just extractor marks. Something a little sharp

When an engineer has to pick a side, he leans towards more reliability. You have an example of that here.

Were the reloads properly barrel drop tested? - http://www.thehighroad.org/showthread.php?t=506678

Are you getting the same marks on factory ammunition?

If the finished rounds' bearing surface was hitting the start of rifling and the bottom of the case was sticking out the barrel a bit, the extractor could be digging into the case base.

The mark is a built in counter. Tells you how many times the brass was fired. :D

Although I see this often on auto loading brass, I do agree that it can be amplified if the brass is way over max length (in need of trimming), or the bullet is impacting the lands during feeding. This will cause the extractor to slam into the top of the case grove, leaving those nicks.
Many here, if not nearly all other reloaders, will tell you that they do not trim there pistol brass at all. I'm one of the few that trims everything I load, and there is good cause to do so when one considers the aspects of SAAMI spec. and why these specifications exist.

Yes, these reloads were barrel drop test and all passed. AOL was set to 1.250 using 200 LSWC bullets.. Factory ammo also shows the same marks/nicks...

Again, it has nothing to do with the load.

Your extractor has a knife sharp edge on it + a strong spring, and is cutting the brass just because it is there doing it.

It has nothing to do with the load.
As you found out with factory loads doing the same thing.

I've sent Ruger a message, I'll wait to hear what there response is.... This gun is only a few months old and don't want to void any warranty by polishing the extractor a bit....

Well good.
But while waiting, see what I said in post #2 again.

I have never seen 45acp brass grow enought to cause issues. Never, not once. Thats in an awful lot of loading too. Nor has anyone that I know, and almost all of my reloading friends are older than me and have been at this for 40 years or so. They would laugh at the thought of trimming 45acp brass.

I know I am laughing!!

But I have only been reloading .45 ACP for pistols and revolvers since 1962.

Maybe there is still time for me to learn how to do it right by trimming that which simply doesn't matter if it chambers?
