What This Cartridge Was Designed to Do

The 7mm Shooting Times Westerner was developed by Layne Simpson as a high-capacity 7 mm hunting cartridge and was later standardized by SAAMI under the abbreviated name 7mm STW.

Typical Rifle Platforms

• Long-action hunting rifles chambered for 7mm STW
• Factory rifles produced after commercial standardization
• Custom long-range hunting rifles with a verified chamber

Compatibility warning: Match the brass to the exact chamber, reamer specification, dies, and rifle. This is especially important for proprietary and non-standardized ELR cartridges.

Best Suited For

• Long-range hunting
• High-velocity 7 mm sporting rifles
• Custom long-action builds
• Handloaders maintaining discontinued or limited-production chamberings

Frequently Asked Questions

Is this loaded ammunition?

No. This listing is for new, unprimed brass cartridge cases only.

Is this cartridge standardized?

SAAMI-recognized as 7mm STW

Should new cases be sized before loading?

Why is this brass produced intermittently?

Demand is specialized, so production is generally scheduled in batches rather than maintained continuously.
