This video provides a detailed guide on reforming cartridge brass, specifically demonstrating how to convert .270 Winchester brass into .30-06 Springfield. The instructor emphasizes the importance of using the correct dies, proper case lubrication techniques to avoid shoulder dents, and the necessity of trimming and deburring the reformed brass. The process is presented as a cost-effective method for handloaders to utilize existing brass for different calibers.

Quick Summary

Reforming cartridge brass involves selecting compatible donor brass (e.g., .270 Win for .30-06), using the correct resizing dies, and applying lubricant sparingly to the case body, avoiding the shoulder. Annealing previously fired brass is recommended. After resizing, trim the brass to the correct length and then chamfer and deburr the case mouth for proper bullet seating.

Frequently Asked Questions

What are the key considerations when selecting brass for reformation?

When reforming brass, ensure the donor case is at least as long as the target case. It must also share the same head size and rim style. For example, .270 Winchester brass can be reformed into .30-06 Springfield because their overall dimensions are very similar.

How should case lubricant be applied during brass reformation?

Apply a light, even coat of case lubricant to the exterior of the brass, focusing on the body. Crucially, avoid lubricating the shoulder area, as excess lube there can cause hydraulic dents or wrinkles in the reformed case.

Why is annealing important before reforming brass?

Annealing brass, especially if it has been fired multiple times, softens the metal. This makes it more pliable and significantly reduces the risk of the case splitting or cracking during the resizing and reforming process.

What are the final steps after resizing and trimming reformed brass?

After resizing and trimming, you must chamfer and bevel the outside of the case mouth to remove sharp edges. Then, deburr the inside of the mouth to ensure smooth bullet seating without shaving the bullet.
