30-30 Brass Problems

[ihmsa70]

I've just started trying to work up some loads for Cowboy Lever Action Silhouette.
I was given a gallon bucket of RP once-fired 30-30 brass.  
When I started to trim for length, (Lee case trimmer mounted in an electric drill), some of the brass seemed to be as crooked as a wet noodle.
I was careful to make sure it wasn't just the way it was held in the shell holder, rotated it, put it aside and tried another case that appeared to be fairly straight, etc.  
How much will this affect accuracy?  (Win. 94, 26" bbl)
Will the cases straighten out any after firing?
I have tried annealing them down the shoulder as far as I dared, didn't seem to have any effect.
I have fired these cases a couple of times, and full-length resized them, no apparent change.
I have reloaded for a lot of different calibers over 50+ years and don't remember having this kind of problem.
Need advice from some of you experienced lever-action shooters.

I'm new to the 30-30 myself, but my first thought is that once-fired brass shouldn't need trimming.  Are they overly long, or are you just trying to even them up?  30-30 necks are pretty thin, if the cutter head is dull it may be torquing them and causing the problem.  My best guesses, let us know how this progresses.

Some as anything inconsistent will but you may not notice it.

Often the cases will grow and over time the mouths will even  up with trimming.  I prefer to trim them all square even if the are a bit on the short side.  One of the benefits of an adjustable case trimmer is it allows me to true up the case mouths no matter the actual length.  
 
I see this a lot with range pickup .30-30 brass.

30-30 brass headspaces on the rim.  As a result it will stretch a little with each fireing.  If you can get it to headspace on the shoulder, like other bottle necked cases, the stretching should be lessoned.  

I have been shooting a 22 Hornet in a Contender, for Hunter Pistol silhouete, for several years.  It has the same exact problem with stretching as the 30-30.  I started using a Lee Collet die with the hornet and my stretching problem went away and I have gotten over 10 reloadings from my brass now and it is still looking good.  I have not had to trim the brass since I started using the collet die.  I have to say that I am shooting a very mild load though.

I just got a 30-30 for Cowboy rifle silhouete.  I bought a Lee Collet die for the 30-30 also.  It seems to have solved the stretching problem and has also improved accuracy.

Have had the same problem, I started using RCBS trim dies on all my loadings and have had great luck with them. Good luck.......Joe.........
