Remington Brass

[Shulaps]

Just wondering if you guys resize new remmy brass or just load it up as is out of the bag?

[NTM]

I've always resized it as most times the hole is oblonged or bent from shipping and/or packaging.

I always treat new brass like it was fired

[Mauser98]

I FL resize(I doubt this does anything other than get the dings out of the neck), then trim/chamfer to square the mouths.

[Shulaps]

I have FL sized them in the past but I thought I would just load it as is till I saw the case mouths. Pretty beat up? I would suspect though that Remington would load them as they are in the bag for there factory ammo.

I neck size all new brass as a matter of course. The necks do get beat up in transit at times.

[Coppertop]

I neck size & clean up the primer hole with any new brass.

Full length resize, as this uniforms the case neck and case mouth.

Trim all to same length, usually 10 thous under SAMI specs, this will make it easy next time you mic them to see if they are stretching at all.

Chamfer the neck inside and outside, then run a stainless brush on a power hand drill, in and out quick in one pass....this puts a nice cross hatch pattern into the neck allowing for uniform bullet pull, also cleans any old lube out.

Next uniform the primer pocket with a bottoming cutter, so ALL primers are seated to the same depth...this allows for uniform ignition.

Last and very important. Get yourself a flashhole uniforming tool. It puts a 60 degrees cut inside the case where the primer flash enters the powder chamber and uniforms the hole with a nice bevel inside. This is important. When they make the cases the flash holes are punched out with a rod... not drilled out like some think ( that would take too long at the factory) as a result of being punched out the holes are VERY inconsistant in shape, thereby making the flame or Brisance of the primer very inconsistant too.

I do all of this to my brass, it eliminates all kinds of problems and makes those groups shrink very tight. I try to eliminate all possibilities, that way if I miss the shot...I know it was me and not from lack of attention to detail when I load.

Hope that helps........

Oh yes and the last good piece of advise, if you want it.

Use a bench rest primer when loading. Yes they are a few pennies each more than normal primers. But there is a reason. They are hand selected for uniformity. And NO you do not need a magnum primer to light magnum charges. Bench rest primers have a longer and more uniform briscance than that of magnum primers. This came from a dear old friend who held three world records in bench shooting, and was never outshot is his particular discipline.

Don't believe it.....go buy a box of 100 and watch the group sizes shrink like a wool sweater in a hot water wash.

I run every piece opf brass through my rifle, new or fired. If it fits back with ease then I neck size only.

I full length size all of my remington brass. In the past I have had a few cases that would not chamber even new in one of my rifles even after neck sizing. Then I chamfer the necks and deburr the flash holes.

I'd agree that for most magnums you don't need a magnum primer but for the bigger mags you do. I tried to use standard primers in my RUM but they produced horrible hang fires. "Click.....................Boom"

[blacktail]

Full length resize and trim to minimum length
After the first firing I just next size
After around the 4th firing I Full length resize the best ones,take a look at the length and trom again
