M305: Rounds Won't Chamber or Extract

Ok so I came home today with my new M305 with long barrel (returned the shorty I had as a straight swap even after I opened and degreased!), degreased, lubed and reassembled. I picked up a couple of .308 A-Zoom snap caps to cycle through the action but ran into a little problem, the bolt does not close far enough to rotate and seat the round. When I cycle the action back, the rounds haven't even been caught by the bolt and simply fall out of the chamber when I tip the rifle back.

Has anyone had a similar situation? Know any fixes?

Thanks for any and all info!

When I was new to my M305 I had a similar sounding problem.

Are you pulling the op rod right back to the heel and letting the tension slam the bolt into position?
I found with my m305 that if I was 'gentle' with the op rod when attempting to put a round into battery the bolt lugs would not be engaged nor would the extractor. Probably because of the lack of force.

No I had not, I will give it a try in the morning where I won't piss off my room mates :p

Sorry for the newbie question, this is my first semi-automatic. Thanks for clearing that up!
 
Yeah, always let the rifle do the work. Dont push the op rod to the chamber, let it go full strenght. Also, when you will load live rounds always load from the mag not the chamber. This will reduce chances for slam fire.
 
Because that's not how the rifle was designed to be operated.
OP, get real ammo, go to your range and follow the directions above (And now below)
Load the mag, insert in rifle, draw the bolt all the way back, let it go so it drives forward under it's own power and shoot til the mag is empty.
Repeat as necessary.
 
Using the rifle as intended at the range would be the best way to go.

With him using snap caps, I assumed he is doing this at home.
Hence the suggestion of neither letting the bolt cycle normally from the mag nor slam a round in the chamber.

I've seen out of specs snap caps in the past. Try with real ammo.

Chamber the round manually and let the bolt close VERY GENTLY.

The extractor wont catch on the rim if you are gentle. It needs force. Its better testing this at a range assuming the round will fire downrange instead of trying to chamber a live round in your basement and risking an accidental discharge.

This bad advice. Not trying to be a #### either.
You baby nothing with these rifles. ALWAYS load from the mag and NEVER do it gently LOL
OR?
Your #### will fall off

Live ammunition at home would be a really bad idea. Unless it is home, home on the range.....

And now I have that song stuck in my head. I'll give the snap caps a try at full draw and release when I get home from work, I'll be taking the rifle out for the first shoot this weekend and I'll give the live ammo a go. I now understand the tough love with this rifle considering the bolt design, my only previous experience with shooting was with a bolt action so I had been concerned I got a lemon when it wasn't going into battery.
 
Insert mag with a slight rocking motion, engaging the front first and rocking back till you feel/hear it click in.
Pull Oprod fully to rear, maintaining a "back and down" hold on the handle.
From it's rear most position, let finger slip off handle and let oprod fly home.
That's the only way these rifles are designed to chamber a round safely.
 
There is a very slight possibility your firing pin may be jammed forward. I have personally had this issue with this rifle. Much better to discover it with a snap cap than a live round. Check that your pin is not protruding through the hole in the bolt when the rifle is positioned muzzle up.
 
Just loaded them into the magazine and into the rifle, pulled the action all the way back and let her fly. Rounds chambered and ejected without issue, the only problem I can foresee is that the snap caps are obviously aluminum and only after 5 cycles each are getting pretty chewed up. Is the M305 so hard on brass as well?
