I have a bolt action that loves Eley Match and Eley Contact. It won’t feed CCI SV.

I have a semi auto that loves Eley Contact (haven’t shot Eley Match in it). It also likes CCI SV and though it doesn’t shoot it as well it’s a lot cheaper! And it still shoots pretty great groups at 50 yards with the CCI.

Neither rifle likes Lapua Center X. Not saying the Lapua isn’t good ammunition but every rifle is unique.
