  • Hey everyone.

  • Lately I've been exploring reloading berdan primed steel cases.

  • I think this is a pretty interesting topic because of the high price of boxer

  • primed brass right now and the really wide availability of

  • what's typically discarded berdan cases. Sometimes they're steel,

  • sometimes they're brass, I found they're usually steel.

  • This is a little bit more time consuming than standard reloading but after you do

  • the conversion you can reload them just like normal

  • I've reloaded steel cases numerous times without issue.

  • In a previous video

  • I made a simple modification to the large rifle boxer primers to fit them

  • into these steel

  • 7.62x39 berdan cases.

  • I thought it was interesting because no special tools were needed to accomplish

  • this.

  • Today's a little different I'm going to show you how I converted the 7.62x54r

  • berdan cases

  • into large rifle boxer cases.

  • So evidently there's numerous sizes of berdan primers

  • the 7.62x54r's have a really huge primer pocket,

  • way too large for a standard large rifle primer.

  • So after trial and error the technique that I finally settled on was creating a

  • a copper bushing from standard

  • quarter-inch copper tubing.

  • You can pick this up at any hardware store, I went and bought one foot of it for this

  • and it cost a little over a dollar.

  • Besides your standard reloading gear you're also going to need a drill

  • and something to cut the copper tubing

  • as well as

  • a primer pocket swager.

  • This is the RCBS

  • swager.

  • It was pretty reasonable, about thirty dollars and it's designed to remove the

  • primer pocket crimp found on some brass.

  • We're going to be using it to form the copper bushings.

  • To get started I'm going to remove the berdan primers

  • from the steel cases using the hydraulic depriming method.

  • I have a more detailed video about this you can watch

  • for clarification.

  • Ok, we'll need to cut our copper tubing into short pieces. I found this was easy to do

  • with a dremel tool and a cutting disc.

  • You can see I've used

  • a deburring tool before making each cut

  • but I've done this previously without deburring and it worked ok.

  • Here I'm removing the berdan anvils and creating a new central flash hole.

  • Removing this anvil makes room for the boxer primer which contains its own integrated anvil.

  • Be careful not to drill all the way through the base

  • you want a reasonable size flash hole.

  • Now at our press we're going to put the primer pocket swaging mandrel in

  • and the case stripper on top of it.

  • You can see how that works.

  • Up here we're got our RCBS primer pocket swaging die.

  • We're going to place our small piece of copper tubing on the lubricated mandrel

  • with the rough side down

  • we're going to get it started

  • by placing a solid object

  • blocking the top of the press

  • simply raising it up

  • and pressing.

  • I've found this is an important process because it starts the copper tubing on

  • the mandrel

  • whereas if you start it in the case it pushes to the bottom of the primer

  • pocket

  • and fills the bottom

  • whereas when you start it on the mandrel halfway

  • it seems to evenly fill out better in the case.

  • Finally we will go ahead and get our case started,

  • get everything lined up and simply press it.

  • And there's our large rifle boxer primer pocket.

  • We simply need to clean up the excess copper that's been squished out of it

  • during the swaging process.

  • Now we're going to remove the excess copper from our cases.

  • Now that we've removed the excess copper

  • one more trip through the primer pocket swager will clean things up real nicely.

  • Now we just go ahead and full-length resize like normal.

  • Now we prime with the standard large rifle primer.

  • Now at this point we've got our live ammo

  • you can continuously reload like you would standard boxer brass.

  • Here we've got our four rounds of 7.62x54r

  • loaded up with 180 grain cast bullets.

  • Loading reloaded ammo into the Mosin Nagant.

  • Previously fired from a Romanian PSL 54c Semi Auto

  • Bullet Casting is a great hobby to compliment reloading.
