I'm wondering, when I buy a new box of factory cartridges, do I dare trust the manufacturer or should I resize and trim the brass before shooting them? What do you all do? | ||

I usually full length size, check OAL, then inside/outside chamfer. I used to ream the flash holes, but gave that up quite some time ago. | |||

Full length resizing should not be necessary but yes, do neck size. Fire form your brass before thinking of trimming. What brass are you using? | |||

Offhand, I don't know of any way to resize a cartridge. They are speced to begin with at something less than maximum dimensions so that they will fit a chamber with minimum dimensions -- in fact, most factory cartridges are small enough that they rattle around a bit in most factory chambers. So why ever would anyone want to resize a factory cartridge before firing it? | |||

Well, I've heard of factory ammo being used in guns that blow up AND sometimes there are recalls of factory ammunition; not just one box but whole lots of ammo. This means that the ammo manufacturers don't know what they are doing. If they don't put the right powder in some ammo then obviously they could get the dimensions wrong on cases and even bullets. They might even accidentally use magnum primers. | |||

I bought some brand new brass from remington for my .375 H&H. I just happend to notice the neck was out of round on one. I looked thru the whole batch and there were several that didnt suit me. I resized them all. I alos had a hornady casing that was so large the bullet just dropped right in. That was the only one out of 50 though. I have walked in the foot prints of the elephant, listened to lion roar and met the buffalo on his turf. I shall never be the same. | |||

+1 I dont see much point in FL sizing since they need to fireform to your chamber anyway. But it seems like most of the time there will be dinged up, out of round necks, so I neck size to ensure a square fit and to prevent a damaged neck. I have never trimmed a new case.

Do you resize them? | |||

"Resizing" factory cartridges would hardly correct for that! I've never heard of factory ammo blowing up anything but I have heard of idiots shooting with obstructed bores and then blaming the ammo. | |||

I only NS the ones that are dented.FL sizing them is a waste of time and work hardens the brass. | |||

I hear what you're saying. Probably ought to weight the powder and check the primers as well. As for factory ammo not blowing up anything, I saw a guy probably a year ago now who in the past had a very severe arm injury when a shotgun blew up. He and another person, I believe his grandson, had been shooting it with the same factory ammo prior to the blowup with no problem. As far as he knew, the shotgun was in good mechanical condition before the tragic incident. | |||

Every shotgun that I have known to blow up was from an object in the barrel.Might have had a squib load right before he fired. | |||

If you are using quality brass, no. If you're using bulk brass it's probably a good idea. Ken.... "The trouble with our liberal friends is not that they are ignorant, but that they know so much that isn't so. " - Ronald Reagan | |||

In the thousands and thousands of pieces of brass I have bought, I have never had a case that wouldn't chamber. Dented necks, oilcan shoulders, yes but they would still chamber handily. If I ever do get a piece that won't chamber, I may change my tune but until them, imo, it's just another one of those anal things that some reloaders like to do. Aim for the exit hole | |||

The necks are seldom round, particularly if bulk packaged in bags. I just back the resizing die off a bit and run them all through. | |||

I always full length size, equalize the primer pocket and flash-hole and run it through the trimmer (most are well short of needing to be trimmed) on new brass. After that first firing my cases get neck sized only leaving just enough of the neck unsized to help center the round in the chamber. Since I started doing this 40+ years ago I can make ammo that always shoots well under MOA groups. Speer, Sierra, Lyman, Hornady, Hodgdon have reliable reloading data. You won't find it on so and so's web page. | |||
