Very efficient and cost effective when every link in the chain is running smoothly.I would agree, however it is not just ammo related. There are shortages across several industries that I don't understand. I hear the raw materials shortage claim from some companies I try to buy from. I've had a tiller on order with Bush Hog since the end of March and they still can't deliver. My 20 year old truck is about due replacement, but inventory of what I am looking for is few and far between. UTV availability is no where near the demand. It took weeks for the pellet grill I ordered to ship from the factory. My gut says it is supply chain problem for materials due to our reliance on limited sources and JIT purchasing.
Just in time inventory programs have not helped except in operating expenses for business. I understand the concept and works fine as long as everything runs smoothly, but let a problem hit somewhere in the chain and things come to a stop.
Most manufactures I know of now all work on the Just In Time concept because it is good for the bottom line and produces more cash to the stock holders.
