Barrel twist and published data

Post by madang55 » 01 Oct 2025, 11:02 am

223R HOWA 20inch fluted, 1:8 twist.
ADI book shows the data for 223R as a 1:12 twist. Is using this data for my HOWA, especially for the heavier 69gr TMK, going to cause a problem, or should I back off a bit?

It will be absolutely fine.
