.444 Marlin case length

edited December 2007 in Perry Shooter Competition Shooting and Reloading Forum
I picked up a couple boxes of brass at the dump I shoot at and the ones with Hornady headstamp are very short and the R P cases are right at the trim to length or just a little short.

Hornady headstamp .444 Marlin case length 2.060 - 2.067 inches
R P headstamp .444 Marlin case length 2.210 - 2.215 inches

Whats up with that

all the cases appear to be once fired and never trimmed.

    I would measure the OD of each. If the OD of the Hornady Brass is noticably different than the RP, it could explain the difference. It could be that the Hornady brass was fired in a gun with an oversized chamber allowing the brass to expand outward, therefore shortening it. I would not assume that the brass was fired from the same gun unless you witnessed it yourself, which from your post, I am taking it that you didn't.
    I would run one of the Hornady cases through a FL sizing die and then measure it again.

    I will measure the Dia. sometime but I don't think that that is the answer. 150 thousandths is a lot of shrinkage due to expansion. I can't size them as I don't reload them. I resell range brass and don't want to sell something that is defective. I noticed the difference when I stored the Hornady brass next to the RP brass.

    I'll take all you want to sell cheap. I will resize them to a wildcat round, so those minor differences won't mean a thing to me

    I think I have solved the puzzle about the short brass. Hornady made it that way so they can load and crimp the new Leverloution ammo. These were Leverloution rounds and I think the ogive and ballistic point make the distance from the channelure to the point so long that if they use standard length cases the loaded round exceeds the max overall length. They want the longer ogive and rubber tip so they can get a higher ballistic coefficient but they need it to function and feed in Lever rifles.

    Sounds like you hit the nail on the head. I just read something similar to that on another forum and was coming over here to post it, but you beat me to it.[8D]

    Thanks for the confirmation, I was just speculating.
