is to check a few with the caliper`s.
They didn`t change,have always been available in different sizes,and some just come in one size,and it can vary from 5.47mm-5.56mm,but most are around 5.50mm
You can tell pushing in the Marauder magazine the larger sizes,I have to slightly push with a pencil,but I would still check.
For me,the larger are:
H&N FTT,H&N FT,H&N Barracuda,H&N Cro magnum
JSB Exact
Most of these mentioned come in 5.50-5.53mm,if you can find someone that stocks them.
On the Barracudas,and FTT I just bought from Pyramyd,the just came 5.53mm,just what you need.
Kind Regards,Dizz
