When I was on the competition circuits, reloading was a must due to the volume I was shooting in practice, as well as the accuracy factor between my reloads and factory, which is made for the "average" firearm chamber and function...
Tailored ammo for any weapon should be more accurate than factory if you apply consistent reloading practices...
By buying in bulk at near wholesale prices as it becomes available will save money in the long run as component prices continue to rise steadily...Now that I'm shooting much less than I used to, I have a wide range of supplies on hand and am not bothered by most price swings...My average .224 round will cost about $0.30 to shoot, as opposed to almost a $1.00 per round for factory...my .204 is only slightly higher...
I think it depends on your anticipated shooting needs as to whether it is financially feasible to get into reloading...If you are only using the ammo for hunting purposes and take the time to find the most accurate factory ammo for your firearm, then reloading may not be your cup of tea, but if you shoot for pleasure or competition where you need a copious amount of ammo for practice/plinking, then over a period of 3-5 years, the cost of an individual round drops substantially...
You really need to take into consideration the initial equipment cost investment and, like a business, depreciate that cost over a 3 or 5 year basis...i.e., let's say your total equipment cost is $500 and you depreciate that over 5 years...Your equipment cost is $100 per year, on top of your component cost, but since the equipment will likely last more than the five years, after that point your only ammo cost drops down to the actual component cost and if you buy in bulk for those components, the cost of inventory will drop relative to the current market value in the future on a normal inflation basis...I have a progressive press for my handgun rounds that I've had for over 10 years with no signs of deterioration...
I have recently switched from a .308 to a 6.5 (.264) and my reloading costs have risen due to having to buy new brass, bullets and dies for the round, but since I won't be shooting it a lot, once I get my test loads developed, it will be several years before my cost per round drops and I will still build up a supply of bullets and powder at current prices in anticipation of future components costs..The 150 rounds of brass I have on hand will last several years if I don't run 'hot' loads to blow out the primer pockets and I have several thousand primers on hand from the .308 loading process..So my only expendable costs to anticipate will be for bullets and powder...If I find a good buy on more brass, I will stock up a little, just to have the reserve...
