375 RUM brass

Most people are having a tough time getting 300 brass. You can neck down 375 RUM brass instead it seems to be available at this time.

Shawn,
Is it feasible to size down the 375 rum to 300 rum?

[Shawn Carlock]

You would have to turn the necks most likely but it is doable.

I guarantee it!

On a factory chambered 300 RUM, it may be possible but I have never seen a custom chamber that would allow a 375 RUM to be necked down to 300 RUM without turning some off the necks.

Remember the 338 is dang near perfectly half way between the 308 and 375 so either case will work equally fine.

I have seen in some instances where necking down resulted in truer virgin brass neck run outs. Greatly depends on the die used to do the forming but either way the 375 will work well.

If you have a tight necked Edge made from someone else, be careful on the neck diameter. For that matter, always check loaded neck diameter before shooting any load to make sure it has the proper clearance to the chamber neck.
