My most accurate bullet is Berger 90 gr hpbt Target # 24425 but costs a lot of money. It needs good velocity from my 27.5" barrel that is 1-10 twist. Good powders IMR 4831, IMR4350, H4350.

For an all around bullet, the Sierra 85 gr hpbt #1530 can be very accurate, but its not a Berger grade bullet. IMR 4350 & IMR 4451 work well.

The 100 gr is a 3" group @ 100 yards bullet in my 18" barrel Rem 600 Mohawk. Not enough velocity/RPMs.

The bullets in photo will work with your twist barrel, but maybe not the 100gr?
