DBM Feeding Issue

[jd5521]

If the brass is all the same, it really does sound like the Bergers are engaging the lands?
I would mark the ogive with a marker and make sure you dont have land marks.

I will do this to be sure. Thank you

Brass stays in chamber. All brass is new Norma and all is the same length. I am not engaging the lands I am sure of that.

Thats a real mystery then??

Sounds like you may have a tight neck chamber and maybe the berger is expanding the neck a little differently maybe causing it to stick but also sounds like you have a slight problem with your extracter. David

Necks are for sure larger with the Berger's. Hornady is measuring .3145 and the Berger's are measuring.316

Anyway you can mic your case necks on your different loaded rounds see if any varience

I just fed and extracted 7 of the live Hornady rounds with no issues. I guess I'll have to try the VLD's and see if they measure the same as the elite hunters.

I know I have a hart rifle they built for me and the made the neck pretty tight. David

Take one of your berger rounds put a little vasiline on the neck chamber it see if it will extract if it does you found your problem then clean your gun and go from there. David

If the neck really is THAT tight to where different bullets won't fit, I would be getting it neck reamed because thats not enough clearance.
First check and make sure you dont have build up though. I like to run at least .003" clearance but it should never hang up from a couple tenths variation.

I kind of wonder if maybe his seating die isn't matching up with the long point on the berger and is tweaking it a little when seating but he should be able to feel the difference in the pressure on seating. David

Ya, there is something strange I think because no one would cut a chamber that tight!

I. Agree tight is good just no to tight. David

I don't believe so. I have a saami chamber and from what I'm measuring I am .065 off the lands with the Berger's.

If you didnt have a saami chamber, I would wonder if you didnt have a custom tight necked chamber that was cut for turned brass and you ended up with zero clearance on factory brass.

Always possible gun was chambered with almost worn out reamer
