Can nickel plated brass take more pressure?
I'm thinking there is a lot of nickel plated factory loaded ammo out there and there must be a reason.
I have noticed that the Remington RSAUM and Ultra Mag brass seems a bit on the soft side.
Does anyone know how and have the equipment to test this?
Anyway back to my point. I have been considering switching to nickel plated brass for the Remington RSUAM and Ultra Mag catridges.
I would be running the pressure right under the point where ejector marks and flattened primers occur. Then only neck sizing the cases to 0.001 or 0.002 tension.
I am thinking I may be able to squeeze a bit more out of the Remington nickel plated brass than the seemingly soft regular brass.
Anyone tried this?
I have never messed with nickel plated brass, what are the draw backs?

Re: Can nickel plated brass take more pressure?
dwm,
can niclel plated brass take more pressure NO but it can cause more pressure because of reduced case capacity. the reason that you speak of is so ammo manufacturers can call it "premium" or SPECIAL and charge you 20 more bucks a box. if you do get sucked into this marketing propaganda back off your powder charge 1-2grns or more and work up.

Re: Can nickel plated brass take more pressure?
Hey DWM,
Is more pressure the thing you want or accuracy ? Questions like this can always be pointed to the bench resters , that is to say , " do they use nickel plated brass " I almost forgot to say that corrosion is a factor for those going into excessive enviroments ( salt water ) and perhaps this would justify the nickel

Re: Can nickel plated brass take more pressure?
I heard that remingtons nickel plated brass was about the worst for consistency. I use to buy it for my 22-250's and 25-06's, but since have switched to winchester brass. That being said, I have no custom guns or barrels for that matter, and I still had under .5" loads with the Rem nickel brass.

Re: Can nickel plated brass take more pressure?
Several ammo makers have offered nickel plated brass cases. They are no stronger than plain brass ones. Their hardness can be measured at a machine shop that has a hardness tester; you'll need a couple of flat pieces of the case body wall to test.
Brass starts to extrude at about 70,000 ppsi. The thin coat of nickel on the brass is meaningless as far as strength is concerned.
The only advantage of nickel plated brass cases is they have less resistance to sliding out of a magazine so the make rapid fire with a bolt gun a bit easier. If sizing dies are a bit too rough on the inside, they will soon wear the nickel plating off.

Re: Can nickel plated brass take more pressure?
Bart is right. The pistol guys get slightly better relaibility with nickel because of the slicker finish.
How do you preform various of the precision relaoding steps on nickel plated caese? Neck turning (if you do that)being a prime example.
What I don't like is that the finish comes off / sometimes peels and scratches and leaves sharp edges (although the modern stuff is no doubt slightly better).
If you scratch nickel, chances are it'll scratch your dies. In that vein check this out: http://www.redding-reloading.com/tec...tchedcases.htm
(see point 5).

Re: Can nickel plated brass take more pressure?
It has been mentioned, above. The only justification I know of is a salt water or corrosive environment. Like, you make up a large quantity of special loads and expect them to store for a long time, like for your AR on a boat trip to Tahitti, etc. (not Mexico, BTW, they still fear the coming revolution)
Otherwise, you cannot trim your brass, necks, etc. all the operations we normally do to rifle cases. Pretty much worthless for precision handloading, dulls all your cutting edges, peels off, cut your finger on shrapnel, etc.
It's great for any handgun....
Good hunting. LB
