Brass length vs. overall length

Over the years I've heard a lot about brass length. One of the things I always used to do was to trim brass to close to equal length, hopefully somewhere near factory standard. Recently, I got a hold of some Starline cases, .45 Colt of course, and upon measuring them, found they were shorter than minimum trim length. Has anyone else found this to be the case, or is it just this lot that I have? Its getting near time for me to purchase more .45 Colt brass, and I'm seriously considering going back to Winchester.
Second, does anyone here tailor overall length to specific guns, or do you keep everything within factory specs?

I might as well say, that I do tune specific loads for specific guns. I am not always looking for the rip snorting stomp 'em load, but I always am looking for the solid load with the best accuracy. In the .45 Colt Ruger, I tend to prefer bullets of at least 250 grains, and usually much heavier. The old standby Unique works quite well with 250-255, but when the bullet gets heavy, the powder usually switches to Lil Gun, WW 296, or H110.

Starline

Was the measurement taken after full length sizing? I've been very happy with Starline's consistency, but always lube and size before sorting lengths.  What length did they measure?

Depends

Mak, I tend to load on a limited basis. I don't come anywhere near to matching Al's Factory but I load one or two boxes of handgun or rifle ammo at a time. Rifle cases need to be be correct for headspacing and I check for MOL and trim as needed to insure the cases will work, generally I neck size rifle cases unless there is a serious problem with chambering etc. Straight wall handgun cases seem to be less critical as far as being short in the case length area. If I encounter a batch of cases that are a tad shorter than the normal I adjust my seating accordingly to insure a proper bullet crimp. I don't load hot loads very often so I don't think a short case would affect my loads that much. In the Colt 45 you have to remember there are the shorter Schofield cases that work so a short case length is not a problem if you load it accordingly. Now a maximum length is a little different  so I do check and trim as needed for a case that is too long. Also brass grows as it is fired, or gets stretched is more accurate a statement, so a new case lot that is a bit short may be ok after a loading or two and may even need trimming later on after several firings. I am no expert so these are things I do and look for and I may be wrong so act accordingly with my info. Hope I have helped. Chris

I looked for my notes to find

I looked for my notes to find out if I had written down the length of the brass, and it seems I did not. If I recall correctly the exact measurement was about 1/10th of an inch shorter than my usual trim length of 1.275". Working from memory it seems I used a standard load of unique and a 250 gr. cast RNFP. I am aware that sizing and firing lengthens brass-guess I was just a bit surprised at that initial measurement. I used the standard unique load in order to stretch the brass. Due to Al's question, I just measured the brass after firing and sizing-it now measures 1.280", just a tad long for my purposes, but certainly fine.
It seems to me that Starline may be a little more flexible, or soft than either Winchester or PMC brass. I haven't tried it yet in a +P loading. May load just a few and compare. Thanks for the comments guys.

Off the top of my head

1.280 sounds like about what I get from Starline after resizing their new brass. Plus or minus not much, pretty consistant.
