A lot cheaper than the premium stuff and not much more than factory fresh brass but I'm not sure if they even make it any longer. I did have to take apart and hog out my hand priming tool with a file so that those fat cases would fit for priming.
The edge conversion is simple enough since a barrel swap is all that's needed.

I do know if your handle is "hunt fish eat" you're not gonna want to shoot a whitetailed deer with it unless you like drinking your deer through a straw or turning them into chum. There really and truly isn't a lot left to eat. The shock is incredible and turns meat into purple mush throughout the animal, not just where it's hit. I had always heard that there was no such thing as too dead. I believed this until I shot a deer with a .300RUM and 180gr sirocco bonded factory load. Then I saw what too dead looked like. Mine has been sitting in the back of my safe for close to a decade or more. You never know when a pesky garden rhinoceros is going to show up.

Another word of caution about extended range sessions shooting the .300RUM I went to the range one day and fired a few of boxes of ammo. Mine had the factory brake and I was using a Beartooth recoil pad with all the foam spacers in it. It didn't bruise me or hurt to shoot it at all. The next day my chest was hurting and my wife insisted that I go to the doctor. I didn't even think about the previous days range session. He ran quite a battery of $$$ tests on me and after x rays told me that I had separated my ribs from my sternum. That's when the light went on and I realized that it was the repeated recoil from the RUM that caused it. Not a whole lot the doc can do about it. Yep I wont make that mistake again. Not with full power loads anyway. It took quite a while for my chest to heal up.

Good luck and enjoy your rifle, there has to be a practical purpose for it somewhere.
thanks for the reply it is a normal shank gun very few made i know it was the first one sold in orange county ny in 99 my dad was the sales man at bobs gun exchange. dad said the buyer cam back the next week about the kick dad sent it out to get magnaported end of the season dad got it from the owner then sold it to my brother and sate in his safe for 15 years i got it cheap. i have seen deer killed with them and know the damage. i call it the ginny gun named after the city hunter we used to get years ago. like to maybe pop a deer out past 600 with it once for fun i got 4 doe tags sorry here about your rib i craked my coler bone when i was young from a 600 nitro express. thanks troy.
