if the price difference is a major concern just install musket nipples on your long rifles. me my self I keep a set of musket and a modified nipples for my rifles so I can take advantage of whatever is available I never run lowIt is strange how the Cap Supply varies from place to place. Over here, a couple of years ago no one had them and profiteers were selling them on Naturabuy (Ebay for Frenchies into guns) in bags of ten for 5 euros! Now the supply is pretty constant. the prices are still way higher than yours - 30 euros for a tin of 11's and 25 Euros for a tin of musket caps. I can never work out why the musket caps are cheaper...
