Is this usual?

So i shot 300m electronic this AM, with the purpose of using up some .223 rounds I'd made a while ago ( in lockdown ) with not my prefered powder. 

Anyway  my rounds, while slow, were pretty consistant and I managed to get 3 "electronic" touching 5 shot groups, which i was happy with.  I then switched over to some Bisley bought magtech ammo and it was all over the place,  still within the 4 ring I'd say, but  vertical and  horizontal edges,  is this typical of cheap factory ammo?

Some barrels don't group well with some ammunition price be dammed. Some it just doesn't matter what you use they group fine.

My .223 is VERY sensitive to load. (CZ527 in Formrifle stock). Well worth spending time developing what your gun likes, though it sounds as though you have.
