1) Im in no way insinuating Prime isnt worth the price or everyone should be reloading.
2) Having said that, the post i initially replied to said "stop reloading" insinuating they already had a reloading setup
3) Im not sure I follow your math - for a $1700 setup, you need to shoot ~2800 reloads (at a savings of ~$0.60/rd) to pay for your reloading setup. After that point, youre $0.60 per round loaded ahead vs buying factory ammo.
reloading setup cost = $1700 (which is not needed to produce 5 SD ammo - same results can be had from a $400 setup at the cost of time - which for me is not a cost as I enjoy reloading as a hobby)
Prime cost (minus selling the brass) = $1.15
Reloading CPR = $0.55
Savings per round reloaded = $0.60
$1700/$0.60 = 2833 rounds to pay for the reloading equipment
I think you misunderstood what I'm saying. I'm not saying Prime is worth me giving up loading, nor am I saying you need a Co-Ax, Giraud, FX120i, etc, to cut your SDs into the single digits, since I was doing it on a beam scale and a RCBS. Here's the math I used:
Once you get close to $2700, the cost between Prime and handloads are negligible. I didn't check the price, but you said $1.60 per Prime round, ignoring any selling of brass, so $2700 on Prime means you can buy 1687 rounds (let's just round up to 1700 since they come in 20 round boxes). For me, and my $1700 in reloading equipment, to equal $2700, I need $1000 of handloads, which you said cost $0.60 cents apiece, or 1666 rounds, which is pretty close to the amount of Prime ammo I mentioned earlier. Let's say you can get that down to 50 cents a round, then you'll have an even 2000 rounds. EDIT: If you have a less expensive reloading setup, the dollar amount obviously shrinks before you reach equal money spent per round on factory rounds v. handloaded. If your reloading gear cost you $400, your looking at 660 rounds of handloaded ammo at 60 cents apiece, for a total of $1060 to get you to the same dollar per round of Prime ammo.
With that said, what I'm saying is the amortization of the initial cost to get set up to reload needs to be taken into consideration. Even a $400 setup needs to be used 40,000 times before its cost is equivalent to one cent per loaded round (this doesn't mean every time you pull the lever, since I pull the lever once to resize, once to set neck tension with my mandrel, and once to seat a bullet, so for every round you'll have three pulls). After those initial 1666 or 2000 rounds, the system begins to pay for itself. For instance, at 3000 rounds (I'm just going to say 50 cents apiece so the math is easier), the cost per round is now a little over $1.06 (3000 rounds at 50 cents apiece is $1500. Add in the cost of my equipment and divide by the 3000 rounds), including the amortization of the equipment. Obviously the less expensive your setup, the lower the cost per round. Those same 3000 rounds on a $400 setup means each round is now only $0.63, with the cost of the equipment factored in. I have to also say the reason I'm willing to spend $1700 on reloading gear is because A) I enjoy reloading, as you also indicated, and B) it minimizes the time I spend at the bench. The jump from my Chargemaster to the FX120i with auto-thrower cut my time significantly. The Giraud is essentially a multi-tasking masterpiece, since it allows me to trim, chamfer, and debur in seconds, as opposed to the old hand crank trimmer, followed by hand chamfering and deburring.
I will say this: I tend to keep a stock of factory rounds on hand, just in case life happens and I can't get to my reloading bench. If you're like me and you have a few "wildcats" that aren't offered commercially (6 Dasher, 25 Creedmoor, and to a lesser extent, 6XC, though David Tubbs does or used to offer loaded rounds), I have no choice but to roll my own. So it's nice to see quality factory ammo for those times I can't get to load before a match.
