i recently made 700 rounds. i used 230 grain FMJ on mixed brass. mostly winchester and some of that shiny federal stuff. 4.9 grains of hp-38. they are all seated to 1.270" i measured seating depth after each 10 rounds. never varied more than .002" i went to shoot friday and all did not go well. i was shooting a ruger p-90. i've put about 500 rounds of factory lods through it already. about 2 or 3 rounds from the 8 round mag would not load fully.the slide would cycle all the way back, the strip a new round and continue forward to battery. on the "bad" rounds the slide would stop about 3/8" from full forward. i put the safety on and could tap the rear of the slide forward and it would seat fully. i just verified the brass was trimmed to correct length, i read .898 on my micrometer, just what i'm told is the max. any idea what the problem is?

  Almost too many variables here. Your reloads are almost to the max in length. Manuel shows 1.275 is max for your bullet. So that may not be the problem. New guns with new fully loaded magazines will sometimes do what you describe, just because everything is new and tight, especially springs. Try loading fewer cartridges in a mag. and see if you still get the problems. If so, try a Lee factory crimp die. This die will resize the entire loaded round and often solves the problem you have described.
  
  Hope this helps.

  Cliff is right about the new gun and a tight chamber. 45 ACPs should not be roll crimped, but a firm taper crimp might help. Check the size of the bullets you are using. A tight chamber and very slightly oversized bullets could produce the same problems.

  I sure dont wanna piss anybody off so I'll say this as best i can. Maybe it's the gun. I used a Glock with some of my reloads and had a few problems also. Reloads are something you not only have to figure out what is best for the kind of shooting you want to do, but best for the gun. For instance if you maxed out the .45 an put it in a Glock or an Heckler and Kock, Kimber and maybe a few more, you'd have better luck. Try reducing the powder or going with a different powder all together. Dont mean to knock your gun or nothing[8D]
  
  New gun??? No, honey, I've had it for years.

  For less than 10 bucks you can get a Lee factory crimp die, it was the best investment I ever made in reloading.

  You need a case gauge and as others have said a taper crimp die. Dillon has the gauge and the LEE die will work just fine. Try taking the gun apart and put each round in the barrel if you don't have the gauge. They should drop right in with gravity. John

  well, the problem wasnt the reloads. a gunsmith had bent my extractor too far in. it was getting stuck behind the case sometimes. not my fault. problem has been fixed.
