Re: Making 338 Rum brass

shot them up. the sharp corner on the shoulder came back as i thought.

for some reason 1 of the loaded cases was harder to chamber then the others.

now just tell too many people or we won't be able to find 300 rum brass. haha

thanks to all who replied.

Re: Making 338 Rum brass

I followed the process with the sizing wax. It worked well, but I actually got better results by pulling the expander from the .338 RUM die and formed the shoulder first. Then I put the expander back in the die and ran the case through one more time. I trimmed and annealed the cases before loading them. After three reloading cycles, all of the cases are still in great shape.

Re: Making 338 Rum brass

I want to bring this thread back to life! Have many of you guys done this lately? Is it worth it? How exactly do you safely do it? 189.99 for 100 rounds of Norma brass right now less than $2 a piece. $65.00 for 25 Nosler 338 rum brass $2.6 a piece.

Re: Making 338 Rum brass

it worked back then and it works today. I've done it lately and nothing to it, with .300 and 7mm RUM. The only difference is that there is more happening to the 7mm brass so I anneal first.

If you try to go with a full length sizer you will have to take about 30-40 seconds to push the brass into your sizer. Otherwise you will collapse the case. I made a wildcat 6.5 using .300RUM or 7RUM with the shoulder pushed back about .100". I have a couple sizer dies that push a little of the shoulder at a time and works every time with no losses.
