new brass

[watab kid]

ive had trouble loading two different "new brass" recently , one was starline , the recent is winchester , 

 

prefice this to say all my older once fired runs great through my loader and works fin , im loading 45colt , 200grn RNFP 52 bullets , my crimp is great on the old brass , 

 

the new brass crimps OK or so it looks but the bullets are not held - they slip further into the case , i know i can tighten my crimp , but it works fine with my old brass , ive considered ordering some 54 bullets for this purpose but is that the right answer ? ive been delaying ordering till i get this figured out , i dont want to order them when its only for 100 pieces of brass when after i fire them they will be fine with my 52s and my current crimp , 

 

im probably overthinking to avoid resetting the crimp or ordering a box of 54s that i probably could use in my webley 45AR reloads anyway ............

I found I had to trim, deburr and size my new unfired brass from one of the brands you mentioned. 

The other, (*-*) was not bad at all, I just deburred it for peace of mind. It was nice and square across the mouth of the case.

The other, not so much, unless I got a bad batch the last time I bought that brand of brass.

Did you resize the new brass before loading?

I just bought 500 new .38spl Starline  brass. I’ve fired about 100-150 so far no problems. Crimp seems just fine. I never thought to do anything to new brass! Another thing to pay attention to.

I use StarLine 45colt and have never done anything but load em like any other brass. Including lubing and running through the sizer die. I do get a few that split the first time used and then they go for years.

Did you check the case length...in case the new brass happen to be a hair shorter?

[Alpo]

I would always run new brass through the sizer. Not so much to "shrink it down", but to make sure the mouth was square and the case was round.

 

You have a sack full of dentable objects. It just makes sense to verify that they're not damaged in transit.

[The Original Lumpy Gritz]

Always size new brass.

Are you using a roll-crimp? 

If not, you should.....

I always resize new brass. All new brass. 
I also pick 10 or 12 out of the bunch and measure the length after resizing just to be sure they’re in spec. Occasionally I will find some that need a trim. 
What’s funny is I had some Starline .45 Colt that I bought new a few years ago. 200 rounds. I recently brought them out to hand load. I measured their length. They were too short. I resized them and they all became 1.270”. Trim length on .45 Colt is 1.280”

I like to make sure my brass is all the same length that way I don’t get pressure fluctuations with different crimps for different cases. 
I can worry about crap like that now and address it. I’m retired.
