Lyman Universal Case Trim Pilot #37 for .375

The Lyman Universal Case Trim Pilot #37 for .375 is a replacement pilot for Lyman Universal and AccuTrimmer case trimmers. In addition, Pilot #37 supports several .375-calibre and related cases, including .375 Ruger, .375 Winchester, .38-55, .375 H&H Magnum and .375 Remington Ultra Mag. Lyman identifies the pilot by part number 7822002.

The pilot fits into the Lyman trimmer cutter assembly and helps centre the case during trimming. Therefore, the correct pilot should match the cartridge case being trimmed. For reloaders working with several .375-calibre cartridges, Pilot #37 provides one pilot option for a number of compatible cases.

Lyman Universal Case Trim Pilot #37 for .375 Features

First, Pilot #37 works with Lyman’s Universal and AccuTrimmer systems. As a result, it provides an additional calibre option for reloaders who already use a compatible Lyman trimmer.

Furthermore, Lyman’s current selection chart assigns Pilot #37 to the following cases:

• .375 Ruger
• .375 Winchester
• .38-55
• .375 H&H Magnum
• .375 Remington Ultra Mag.

In addition, Lyman lists the pilot as SKU 7822002. The manufacturer also lists Pilot #37 among its Universal/AccuTrimmer extra pilots.

Because different cartridge cases can require different pilots, check the Lyman selection chart before using the pilot with a particular case. For example, Lyman’s chart assigns Pilot #37 to both .375 Ruger and .375 H&H Magnum, while other cartridge families use different pilot numbers.

Fitment and Cartridge Compatibility

Before trimming, install the correct pilot in the compatible Lyman trimmer according to the trimmer manufacturer’s instructions. Then, confirm that the pilot matches the cartridge case you intend to trim.

Pilot #37 covers a useful group of .375-calibre cases. However, the listed applications also include .38-55, so the pilot should not be selected from bullet diameter alone. Instead, use the cartridge designation and Lyman’s selection chart to confirm the correct pilot.

For .375 Ruger, Lyman lists Pilot #37 together with shell holder #13. Similarly, .375 H&H Magnum and .375 Remington Ultra Mag. use Pilot #37 with shell holder #13. By comparison, .375 Winchester and .38-55 use Pilot #37 with shell holder #6.

Therefore, Pilot #37 can cover several cartridges while the required shell holder may differ between cases. This distinction matters when setting up a Universal or AccuTrimmer system.

After fitting the pilot, check that the case sits correctly in the trimmer before starting the trimming operation. Finally, confirm the required case length using the loading data or case specifications for the cartridge being prepared.

Specifications and Compatibility

In summary, the Lyman Universal Case Trim Pilot #37 for .375 provides a dedicated pilot for a range of compatible cartridges. In particular, it covers .375 Ruger, .375 Winchester, .38-55, .375 H&H Magnum and .375 Remington Ultra Mag. As a result, it gives users of compatible Lyman trimmers an additional option when preparing these cases.
