DB10 Purchased new - FTF malfunctions
« on: April 21, 2018, 11:33:21 AM »
Bought a new DB10 a few weeks ago.  Was sighting in at 50 by removing lower and looking through barrel.  First shot was dead center.  So happy there.  Planned to move further out but had lots of FTF issues.  In fact, i don’t think it ever auto fed a next round.  Went home, looked at manual and realized that it might be the ammo.  (Cheap polish made for about $13 a box of 20).  Will go back to the range with some Remington .308.  Hopefully, this will solve the problem?  I disassembled and noticed some metal flakes on the bolt while cleaning and oiling.   Will try ammo first, then maybe mags?  Will try to keep it wet.  Maybe it needs good ammo and good break in?  Thoughts anyone?  Thx

The projectile looks crooked on a couple of those? May just be an illusion. Those rounds were used with reloaded cases was it? I know the chamber in mine is extremely  tight and it won't chamber handloads that ran through my dpms.

Wow. They DO look crooked. Doesn't look like an illusion to me.

yeah, the bent ones are from the malfunctions.  They were bent during the FTFs.  Also, some are shorter than they should be.  So i’m hoping it’s mainly inferior ammo.   The tolerances might be off which is what the manual warned about using anything but domestically made .308.

Definitely should stick to quality ammo at least during break in.

Took new DB10 to range for sight in. Used Winchester fmj factory ammo. First three fired ok. Next had a ftf. Could not eject the round. Removed upper, re-cocked the hammer. replaced upper, round fired. This happened 5 times more times. Looked at the primers. Looks like light primer strikes. Examined the hammer and spring. Hammer spring seemed weak. Will try some different ammo And go from there. Anybody else have this problem? Thanks.

UPDATE - bought a Magpul Pmag.  Oiled the bolt assembly really well,  used Remington Core lokt ammo.  Fed just fine.  Tried monarch soft point ammo and fed fairly well with one FTF.  Tried some Russian ammo again and had jams again.  I noticed the Remington and Monarch soft point ammo was 1/16 to 1/8 in. Shorter than the Russian made stuff.  I think I’ll stick with Remington Core Lokt or try some Hornady in the future.

   100 yards while adjusting 6 x 20 x 50 scope.  Now that FTF issue is solved, will work harder at getting zeroed in to 1 in high at 100 yds.

Think I finally have feeding issues worked out by oiling and shooting approx 100 rounds.  Was shooting at a steel plate at about 320 yards.  Was able to hit it pretty consistently with hornady ammo.  it was really windy so I didn’t bother to try adjusting the scope.   
scope is a Center Point 6 x 20 x 50 bought at Academy for about $90.  Bipod for $17 on Amazon.  Monopod about $30.  offset 45 deg iron sights for $40.  i’m really happy with this setup for right around $1000.

I realize this is an old thread, but I'm posting here vs. starting a new thread since I'm having the same basic issue as the OP.

I have a new DB10 ELB and my first range visit was a bit disappointing.  I had 5 light primer strikes in 50 rounds.  This happened with a variety of ammo (PPU M80, Black Hills 168 HPBT match, Remmington 180 Core-Lokt, Federal 168 Gold Medal).  The primer strikes are very light, with only a very small depression on the primer.  I gave up after 50 rounds and called it a day.

I oiled and cleaned the gun before heading out, FWIW.  I'm using run of the mill PMAGs, and no other mods to the rifle except a scope.

I'm hoping things improve with a bit more break-in, but I have to say I'm a bit disappointed with my first outing with my first DB firearm.

Have you been able to take the DB10 out again?

You said you oiled it.  Have you had the BCG out of the weapon and have you been able to pull the firing pin and make sure it is undamaged and well oiled?  If you didn't oil that, the oil away from the BCG won't reach it.

I have not been back to the range with the DB10 yet.  After speaking to DB tech support, they are sending a new BCG, so I'm waiting on that.

Yes, I have had the original BCG out of the weapon twice.  Once, before the range, which including disassembling the BCG (bolt, firing pin, extractor) and oiling them thoroughly with G96.  The firing pin and all the components look normal to my non-armorer's eye.

Fingers crossed the new BCG plus some more rounds down range to loosen things up will solve the issue.
