Casing Failure

Post by JEBar » Tue Mar 24, 2020 1:42 pm

last year I decided to mount a new scope on our 1992 vintage Remington Model 700 chambered for 300 WBY Mag .... back when I hunted with a club that had fields a square mile or larger, it was my go to deer rife .... my bullet of choice is a 180 gr Nosler Ballistic Tip for nonhunting shooting .... for big game hunting I load 180 gr Nosler Accubond bullets .... if/when non-lead bullets are required I load 180 gr Nosler E-tips .... both of these bullets pattern very close to the Ballistic Tips .... when pushed by 84.5 gr of IMR7828 that generates a 3200 fps muzzle velocity, all three are one heck of an accurate, flat shooting, hard hitting, long range rifle round .... no longer hunting with that club, it is isn't a rife that I fire often but do enjoy shooting .... I wasn't able to sight in the scope because the rifle failed to eject every round .... the fired cases literally required me to insert rod down the barrel and use a hammer to drive them .... the last picture shows scratches on the cases .... all of the cases I have were made by R-P .... all had been reloaded several times .... the silver ones were a problem, the brass ones did fine .... in speaking with a gunsmith who I trust I learned that the silver coated cases shouldn't be reloaded more than once or twice .... whatever type of metal they are made of simply doesn't react well to the violent expansion characteristic of such high pressure loads .... the next time I'm able to sit down at our loading desk, I plan to pull all of the bullets and remove the powder .... my plan is to discard all of the silver colored R-P cases that have been fired .... I do have a bucket with a good number of new ones and will load them once and then discard them .... I have also placed an order for new Hornady brass that I'll use once all of the silver R-P cases are gone

Throw that nickel plated brass far away! I like it for new self defense handgun ammo, for a number of reasons, but not for reloading. It’s not just R-P, any brand can cause problems.

I keep all once fired brass for reloading but the nickel ones go directly in the trash.

whatever type of metal they are made of simply doesn't react well to the violent expansion characteristic of such high pressure loads .
I feel your being a little unfair to the brass.

I don't know how much (if any) is brass is in a case .... apparently, they are nickle plated .... I do know that I haven't had the same issue with the R-P cases that look like brass

I have had the same experience with nickle plated brass as so many others have had, including our friend, TxGunrunner.

Because they are brass.

I have never loaded NP rifles cases but over the years I have loaded NP pistol cases and typically they do not last near as long and sometimes split after only a couple loadings. Also its not uncommon for the rims to split during normal flaring operation. Also NP cases have a funny 'feel' going through the resizing die.

Several years ago I was very short on 'real' .357 brass and was loading up a lot of .357 with NP and was glad to replenish my real 'brass' supply.

If its all ya have for pistol I'd say use it but replace with 'brass' as soon as possible - and never reload NP rifle brass.
