Resize new brass?

[Harpo]

Just treated myself to some new Winchester brass (my first ever!) in 45 Colt. When I went to load, I found that I must resize it to keep the bullets (.452 Lazer Cast) from dropping all the way in...

Is it normally necessary to resize new brass?

Thanks,
Harpo

I always resize new brass. Always. Then I trim and chamfer. The only difference in how I treat new brass from fired brass is that I neck size fired brass if it's for a bolt action rifle. Otherwise I FL resize.

"...normally necessary to..." Yep. New brass gets loaded the same way any brass gets loaded. Check the lengths and trim 'em all to the same length as well.

Thanks folks! I learned something else, too: don't put 38 and 45 brass together in the tumbler!

Only thing I don't do to new brass that I do to used brass is de-cap or tumble/clean it. All other applications apply from measuring, inspecting, re-sizing on . . .

"...don't put 38 and 45 brass together..." It's worse with .45 ACP's and 9mm's.

If the case mouths are fairly round I've always just loaded and shot new brass, skipping the FL sizing die.

I size all new brass. For revolver brass I size it, fire it once, then size it again, then trim it all to length after that first fireing/resizing.

Size all new brass. Here are some important reason whys.

1 case uniformity of course
2 most important. Even though they are new they get rattled around through shipping. buy a few bags of new brass. Eventually you will see some with the case mouths with dings or a little out of round.

You need to fix these. Full length sizing then trim. i have seen some pretty shotty flash holes too. its best to go through them. usually a piece of brass will be sticking out. its all minor but im shooting quality not junk.

New bulk brass yes, new primed brass no. All the primed brass I have bought in the past, and I am talking 20+ years ago, came in foam blocks and have always measured proper trim length. With that said I am not sure what the condition of new primed brass is today, but if it measures in spec I wouldn't resize.

With new brass for handguns I've never bothered resizing them as they have always fit the chamber like a factory loaded case. I do chamfer the inside and outside of the case mouth though.

Sounds like bragging to me. New Brass
Did ya hit the lottery??

The last time I had new brass I treated
it like it was once fired except for initial
inspection, and polishing.

I treat all brass the same unless they are new primered and the last time I got that, I was in a pinch and even then, I still resized without the decapping pin.

Inspect, FL size, measure, trim if needed, ect ect and so on and so forth...

What can I say, I'm paranoid that I will miss that "ONE" case of doom...

Winchester 45 Colt brass is made to accept .454 dia. bullets and has been since its inception. Carry over from the original 45 Colt dimensions. I use Starline and Remington without sizing, Magtech (CBC) varies.

Lyman makes some nifty little plastic net bags, you can bag the different sizes ,tape the bag shut with masking tape and drop them in the tumbler.

The drawback (there's always at least one, ain't there?) you can only do a small amount at a time, about 50 pieces at a time and it takes longer to polish, small rifle and pistol cases work the best.
