Third Generation Shooters Supply has Remington #11 caps for $2.99 plus hazmat. Bought some at their store in OK City about a month ago. They also have .50 caliber Hornady 385grain conicals at a good price.
We have had a shortage of .22 rim fire as everyone else. Remington and CCI caps have never been in short supply. Our Goex Dist. Co. has had a big supply of black powder.
Smokeless powder and primers are much more available. The .22 RF is getting easier to find.
