Winchester Silvertip JHP 10mm Auto Ammunition Test and Review

By Bruce F

I was really looking forward to testing this load because I had read reports that the Winchester 10mm Silvertip JHP was one of the last full power 10mm loads coming out of the Win/Rem/Fed Big 3 US ammunition producers. I had many offers from blog readers to supply me with the ammunition for the test, but I turned them all down and waited for new production from Winchester. Winchester released new stocks of 10mm Silvertips in December 2015. The ammunition tested was part of that production run so it should represent the current production ammunition.

Test Pistol:

Test Protocol:
Step 1) Measure and record temperature and relative humidity.
Step 2) Run a 5 shot velocity average over a ProChrono Digital Chronograph at a distance of 10 feet.
Step 3) Run various terminal test shots, with and without simulated clothing barriers, into a block of Clear Ballistics Gel that has a similar density to 10% ordnance gelatin. Shot distance is 10 feet.
Step 4) Run a 600 fps calibration test bb shot into the Clear Ballistics gel block and record penetration depth to verify density.
