Here is another way to look at it. If you shoot only a little each year, and your rifle is accurate with lets say two pellets. A box of pellets might last you a couple seasons. They are easy to handle, and deal with. So for a person that shoots very little while at the same time getting good accuracy, they might very well be worth the extra money.

For instance, I have a Remington Genesis. I discovered that with two pellets of Pyrodex RS and a 250 grain Barnes MZ Expander, the accuracy is exceptional. It this was my only rifle, and I shot very little target range stuff, then a box of pellets would be a good deal.

Unfortunately I shoot four to six days a week, so loose powder is much more cost effective for me.
