When they first appeared in my area, I purchased a brick of each of their .22 LR. I think I had 4 varities, subsonics, 40 gr, 36 gr. HV, plated etc. don't remember exactly. Used them with my range testing of other .22 ammo and they were OK. I have the targets and notes to compare. as I recall they were about midquality for grouping at 50, 75, and 100 yds. Also used a few in pistol but again nothing special IMO.
However, I did buy a few more bricks of the better types Fiochi of the bunch. Since then, price has gone up (no surprise) so I stick with the favorites for my guns. Have about 6 bricks of assorted left which I shoot a box of 50 sometimes for the fun of testing rds. against rds.
Also have about 500+ rds of assorted .223's but have not fired them yet. Purchased them when on sale more or less to collect the brass for reloading. Some boxes of 50 and some 20/box. Different weights, v-max and other types amound by supply.
If the price is good, I would buy more.
In .223, I would buy more just because they (.223) are geting hard to find.
