Worked pretty good for groundhogs Will have to try the 454 next time

If you say that's a groundhog, I'll just have to take your word for it.

Good shot , as for the 454 on chucks a 200gr hor. HP just about turns them inside out!

What distance did you take it at?

It was only about 20 yards. I snuck up on him while he was in some tall grass. When he stood up to check things out I shot him. About a thumb sized entry wound and a fist sized exit. factory 350 grn XTP.

what did that cost you ...i'd figure around $4 bucks?

Nope only about $2.25. My 50 caliber pilot will be here today and I can get to reloading then it will only be about .55 a pop. I only bought 1 box of factory ammo and have no intentions of buying anymore. All the load data I have found says to use a large rifle primer and that is what starline brass is made to accept. Hornady still uses a pistol primer which makes their brass useless for reloading. I emailed Hornady about it and they told me that the change to a rifle primer was made mid year and they did not know if they would change to it in the future or not. But anyways that was the best spent 2.25 I have spent lately!

Hey, send me that useless brass! Seriously, Troy, if you have a large rifle primer pocket uniformer or know someone who does, you can deepen those pockets .006" and then use them with the large rifle primers. Of course, you must still make sure your primers are below flush with the case head.

NEW 500 S&W (R) Updated 9/30/03 Initial run of 500 S&W mag cases was built to use large pistol primer per Smith & Wesson and Cor-bon specifications. On July 28, 2003, Smith & Wesson and Cor-bon changed specification of primer pocket to be large rifle. Rifle primers are same diameter as pistol except they are approximately .006 taller. This was done to prevent primer from being pierced by firing pin when loaded with max loads and heavy bullets (bullets over 400 grains). It was determined that hole in primer allowed pressure to damage firing pin and bushing, kind of like a cutting torch and the harder cup of a rifle primer will prevent occurrence. All cases sold by Starline, Inc. after July 28, 2003, will contain a large rifle primer pocket to accept a large rifle primer. Hodgdon Powder has generated load data which recommends using Win. Large Rifle Primers. Click here to view. Cor-bon has also tested and recommends CCI 250 primers (Large Mag Rifle). Our new cases will have an "R" after the "Mag" on head stamp to signify rifle pocket. If you have previously purchased 500 cases without "R" on head stamp and wish to modify, you can use a large rifle pocket uniformer to deepen primer pocket to accept large rifle primers by deepening pocket approx. .006. This will not affect integrity of case. For concerns regarding situation contact Smith & Wesson or Cor-bon as they designed case and subsequently changed it.
