The .30 Remington cartridge was developed in 1906. It was Remington’s rimless answer to the Winchester .30-30. It was available commercially until the 1980’s, but now it’s a handloader’s prospect at best. It’s the parent case for 6.8 SPC and later the .224 Valkyrie. Cases are difficult to come by but can be easily made from .30-30 Winchester if you have a lathe handy. It’s time consuming to make, however. Once you have made the cases they last a long time because this is a lower pressure loading. .30-30 Winchester load data can be used, but stick with lower pressure ammunition data since the guns that are chambered for this cartridge are model 8 Remingtons and 141’s.

I start out with standard .30-30 Winchester cases and trim the rim down to .6.8 SPC dimensions.

Using Dykem blue, I next mark the position of the extractor claw cut. Again, I refer to 6.8 SPC dimensions.

Once the extractor claw cut has been made, no further modification to the cases are really necessary.

From left to right the cases are lined up in the order they were processed. Standard .30-30 Winchester. Rim turned down. Extractor claw cut. Final polishing of new made .30 Remington case ready to load. Please keep in mind that you will still be able to read the original.30-30 case head stamping. If you have a rifle in .30-30 in addition to .30 Remington, you’ll need to keep the ammunition stored separately so you don’t get them confused. You should be able to visually identify the difference because the .30-30 is a rimmed cartridge. You should be able to use these modified cartridge cases for .25 Remington and .32 Remington as well with a bit of case annealing.
