Prior to this morning this bullet has always been shot using Federal 209A primers. Ignition has been perfect, and the Bestill breech plug used has been 100% blow by free.
This morning it was decided to try the Remington STS primer just to satisfy a little curiosity. Because the STS primers are so much shorter shooting them requires a longer breech plug be installed in the Omega rifle. A Bestill plug cut to length just for the STS primer was utilized; the photo shows there was zero blow by.
Five shots were made at the top target.
