Sierra Sports Master 10mm (.400) 135 grain JHP bullets are jacketed hollow point reloading components for handloaders working with the 10mm Auto and .40 calibre, supplied 100 to the box. Sierra's serrated Power Jacket is engineered to expand uniformly along the jacket's cut lines on impact, giving consistent weight retention and reliable energy transfer over a wide range of velocities. At .400 inches diameter with a flat base, this lighter 135 grain weight suits handloaders wanting a faster, flatter-shooting 10mm load for range work, practical shooting or personal defence practice. These are component bullets only, not loaded ammunition, intended for reloaders developing their own 10mm loads rather than for direct use in a cartridge. Non-coated, non-lead-free, without a cannelure, and carrying a G1 ballistic coefficient of 0.12, they're manufactured by Sierra in the USA to the same exacting standards handloaders rely on across the Sports Master range.
