Howa Mini Rifles, Builds, and Upgrades

Could someone with a Jefferson 223 bottom metal please load the mag and record quickly cycling the mag through then do it running the bolt slow? Mine was pretty shit but the longer coal would be nice.

Are these Howa known to have a long freebore? I’ve got a 22 arc, with a supposed sammi max coal of 2.260, and I’m not hitting lands in the 80 eldm until 2.350, and 2.405 oal with the McGuire 71. I have a mag to let me load long so I know what answer is, but the coals I’m coming up with to start at .020-.050 off lands aren’t lengths I can find any reference on. Seems like I’m in no mans land for comparing load data for a cartridge with not a lot of info out there…especially for copper bullets. Gun shot lights out with factory stuff loaded to the 2.250 Col.

If no one does it before, I can do it for you when I get home on Tuesday

Cut the 6arc down to 16.5". Total weight with suppressor is just over 7.5lbs, looking at an Airlock can that will bring the length down and weight to just over 7lbs. Haven't rechecked my velocities yet but hoping I'll still be good at 4-500yds.

Checked notes.

First load was 77tmk 24gr xbr 2.375” formed LC brass at 100, second load was formed lapua same recipe at 200 (below picture)

.125” off the lands shoots .5moa for 5. I think I can stretch em to 2.45” and stuff some more XBR in there. Stuck a 1” dot next to group so I could measure

Didn’t have time to shoot the lever loads.
