In my family we shoot a lot of .45acp, about 11 guns and except for when I reload, which is not often anymore, we have found that the best inexpensive, quality target ammo, is whichever of the following three, is on sale, usually $16/$18 a box of 50, is best.

Magtech
Sellier & Bellot
Armscor

Of the three, I really like Sellier & Bellot the best.
