Hi

this is my current set up

m&p performance
magpul afg foregrip
wulf fireball optic
a tech supressor.

i usually shoot cci tactical and my grouping is quite tight at 25 yards indoor after adjusting the scope. after every shoot i field strip and put a few jags through it before it put it away til next time. i tried some aguila and apart from the greasy 'feel' of the round, the grouping stays quite tight again, approximatelt 2".

my local range was out of the tacticals so i bought some cci minimags. the groupings were horrendous. apart from the round nothing has changed. had to adjust the scope again.

what would cause this?


any help and advice is appreciated.
