Hi be world,

I just switched back to zero 180g 40 cal bullets since they became available.

Loaded 300 match rounds.

Drive 3.5 hours to a match

changednothing except a Montana for a zero.

180g

1.185

5.1 n320

the zeros seem to bind up in my match mags. They are so tight that they slow the follower down. They were not feeding well when I tested they by hand. So I switched to particle ammo for the match.

Looking for ideas as to why they would bind up in the mags. They were also super tight. With 20 there was no room to push the top bullet down. With other ammo I have a half round of ammo.

Sti tube

Grams 11 coil and followe

tti base pads

Thanks

For any info

Adam

Different bullets have different ogives, thus different COL.

Next time, start by loading two inert dummy rounds and testing them for fit in magazine and feed and chambering before loading a mess. You may only have to seat the Zero bullets a bit deeper in the case.
