American Single Shot writer Joe Brennan challenged anyone to demonstrate that they could shoot an average of 1/2 MOA with plain based cast bullets. Albertan Dave Patterson met the American challenge. Joe had stated people can shoot the odd 1/2 inch target but are unable to demonstrate an average 1/2 MOA shooting capability which would require shooting a number of groups on a single target on one day.
Dave Patterson of St. Albert shot five-five shot groups in sequence that scored 0.452" at 100 yards with a .32 RKS Miller-DeHass single shot rifle that was breech seated with a Weber seater. The 25 shots were shot in 45 minutes with 5 to 10 KPH winds on February 16 at the Spruce Grove Gun Club. Dave used a 6-24X Burris scope, 235 grain Paul Jones spitzers fired in his 1:11.5 gain twist Ron Smith barrel. He shot his reject bullets that had air pockets and rounded bases. The bullets were NOT swaged and were NOT weighed. The plain based lead bullets were 20:1 Lead:Tin alloy shot at 1,500 fps.
