new reloader question about bulk brass

I am ordering 500 45ACP Starline brass cases and am wondering how much trimming is generally needed on bulk ordered brass in a given lot. Should I automatically just trim them all to the .895 trim to length?

  I have never trimmed pistol brass ever. I have loaded the same .45 brass 10-12 times and not trimmed. I don't think it will be an issue and for pistol calibers it's a waste of time. All of the Starline brass I have used (10mm, .357, .41 mag, 9 super comp and .38 super)has never had a problem. If we were talking rifle brass now that's a different story.

  You may be surprised , I"ve had new brass come in at several thousandths UNDER mininmum. Not from Starline necessarily.
  YOu may be in for a nice surprise,eh?

  .45 brass headspaces on the mouth of the case.
  
  Check the brass. Take NOTHING for granted in reloading. Check everything. Sure...it takes time. Go buy factory ammo if there is not sufficient time to do the job properly.

  I've recycled some S&W 500 from Starline more than twenty times without any measurable case lengthening, but I at least ritually take sampling measurements every single time I reload. At this point I almost do it out of amazement but its also like wearing your seatbelt--its always a good idea and a good habit. Theres a lot at stake here. IMHO, You should "train" yourself to follow safe habits from the very beginning

  I've purchased bulk 38-40 from Starline and not had to trim any. That said, I'd set my calipers for max. allowable and check each one just to be sure. If you want to get really anal you can check the actual length on all and trim to absolute uniformity. Haven't found it necessary myself.
  Good luck.

  I've never trimmed pistol brass and I never will, especially if it's a straight wall case. If it's a bottleneck case like .357 Sig, it is conceivable that after repeated resizing of the neck, you MIGHT need to trim it, but I'd be too damn lazy to do it...I'd just chuck it and get a new piece of brass.
  
  Rifle brass is a different story.

  7.62 x 25 pistol cases need periodic trimming.

  I am not sure how anybody with straight wall magnum cartridges get by WITHOUT trimming cases.
  
  I load for 44 Magnum, 357 Magnum, and 45 ACP. I trim them all.
  
  Why? I have to crimp all of them. The crimping operation is setup on the length of the case. Yes, there is a little bit of "fudge" factor, but not much.
  
  I trim every single case that I reload. But, after the second reload, case growth is very minimal in most instances. 300 Win Magnum usually grows a couple thousandths each firing...as in 0.003 to 0.005". But, these are full tilt loads.
