I use Lawman, Magtech and Blazer with a fair degree of success. I am not a fan of Winchester white box, (imo) it is not as consistent and really dirty.
I try to keep most of my purchases to bulk orders, but impulse buy per box on occassion.
I do shoot 115 gr to practice on occasion when I am working out something, but move to 124 as soon as I think I have mastered "it" (like a new trigger or sight for example) since that is what I carry.
I really try to avoid the cheapest (including reman) because if the poi is not consistent I may not be able to determine the reason - consistent ammo removes at least one variable when I am practicing or working on a change.
(I do not want to start a **** show but) if the end price of
Lawman is $.28/round and something else is $.26/round we are talking $2/100 rounds...for cleaner more consistent shooting. I can go through a lot of rounds but if I go through 500 rounds of 9mm and the cost is $10 more (for cleaner/consistent), I feel like I am getting a good deal on ammo.
Blazer is usually the least expensive stuff I will buy and I I keep it to brass case only - again just for consistency.
I have had good luck with
Norma as well, price is not too bad and very consistent.
