Here is one article I found with a quick google search. Doesn't say a whole lot, but you can buy such little amounts of both and test for yourself, that it really might be worth it to see what your gun likes best..

T1 is making some pretty loud noise in 3-gun and from what I understand, theirs stuff is excellent. AA has been in the game for a long time and they have proven world champions that represent their product. I don't think you can go wrong with any of them..
Apples to Apples reloading versus buying looks a lot like this.. (Buying 1000 rounds of 124jhp re-manufactured rounds (because that what reloads are too) versus rolling your own with the same components FM uses)
Press - $1250 (Dillon 650 with casefeeder, strong mount, dies, scale, calipers, boxes, (cheap) bench, etc)
Brass - $20/1000 for 9mm range pickup
Primers - $30/1000 Can be cheaper but you usually have to order them and pay hazmat, etc)
Powder - $25/pound (7000 grains total divided by 3.5gr/round = 2,000 rounds/pound or $12.50/1000)
Bullets - $95.74/1000 ($47.87/500) Not using bulk pricing because we are comparing apples to apples buying 1000 at a time
Total for the first 1000 rounds (provided press comes completely setup and no primers/bullets/powder is wasted on setup) = $1408.74
How many rounds you need to load to break even so the cost can be compared based on $158.74/1000 compared to the $203.20 for the Freedom equivalent = 28,116 rounds before you are at even money..
Sure, buying components to reload in bulk will save you some greenbacks, but reloading is not necessarily the answer for everyone.. My costs are even a little less than GT's example so it's totally worth it for me..
But on another note, by reloading, I was able to shoot clear through the last scare that the pres was going to take away all of our guns and ammo.. Folks that rely on purchasing ammo had a hard time. Come November, who knows whats going to happen?
