Behind my 338 Lapua watching a bull elk
I also just recieved my M 305 and finally mounted my 3.5 x 10 x 40 VXIII on it.

Just wondering what kind of accuracy you guys are getting out of your rifles???

I have shot 168 Hornady match into 1.5 MOA, 175 SMK into 1.3 - 1.5 MOA and some Lake City Match Ball into 3 MOA???? Not sure what happened to the Lake City ammo. Group was only 1/2 MOA Vertical but 3 MOA horizontal.

Any tips on making the gun perform??
What are some of you favorite loads for the M 305 and have any of you had any luck with the 155 Palma Match bullets???

Oh yeah, Have any of you had your M 305 slam fire of you?!?!?!?! Mine will do it every other mag??? I informed my "smith" and he said it needs to be fixed which I agree, it sure is fun but gets expensive real fast!!!!

Thanks for the info in advance

The LCM is probably OLD. Since they used a tar like substance to seal the bullets into the case neck, and since this seal may or may not have dried out and cracked, OLD LCM ammo sometimes throws larger groups than it should.

Try setting up your reloading press to seat ALL the LCM buttlets just a few thou deeper. This way ALL the bullets will have the same "draw". Last time I played around with this trick, groups shrank about 1/3 of their original size.

If your m14 is slamfiring stop shooting it! get it fixed before the next time you go out. the occasional m305 has exploded....i would not risk shooting a gun that slam fires.

Good advice....unless you don't care much about your looks. That things goes up in your face, you'll be in a world of hurt.....
 
Stop firing the rifle! Do the test after assembly as noted in the sticky in the forum....in alot of cases it might be some of the upgrades made to the rifle....or it is a friday rifle.....

Cheers

To answer your questions in order.

1. I get excellent accuracy whether using irons or glass.

2. Different ammo equals different groups. Use what your eyes and rifle likes. I shoot 147gr ball (Wolff) for fun and sighting in. I use 150 gr SST Hornady to fine tune. And 150gr SSTs for hunting.

4. It is not a gun! It is a rifle. You want to play with a gun, stay home and have a rag handy.

5. Don't use Lake City ammo for reasons available on the internet.

6. Anyone that continues to shoot a rifle that slam fires every other mag should not be in the possesion of a firearm period. And without a wickie do you even know what a slam fire is?

7. You said "my smith" Who the hell is your smith? :confused:

8. #### off troll.:rolleyes:

Sorry mods but this had to be said:runaway:
 
Have you disassembled and cleaned the interior of your bolt? The firing pin channel was clogged with metal debris and grease on mine, and I think it could have produced out-of-battery firings, which is probably what you are seeing, rather than "slam-fires".
And everytime you reassemble it, do the "test-on-assembly" like Morpheus32 said. If it fails any one of those tests, it need to be fixed.
 
OK, sorry for the on topic hijack, but how the heck does an M-14 slamfire? From what I've seen, there is a structure within the reciever that draws the firing pin back as the bolt rotates into battery and should serve to block any forward motion of the firing pin until it's AOK.
 
If it is truly slamfiring, it could be that there is a bunch of cosmo-crud or other buildup in the bolt/firing pin area that has keeps the firing pin forward. I suspect it is more likely some sort of problem with the disconnector as described in the sticky resulting in the hammer following the bolt.

Bottom line; if the rifle is firing out of battery (which happens in either case described above) IT IS NOT SAFE.

Good luck.....

If you have experienced more than a couple slam fires, consider yourself lucky. The M-14 has a free floating firing pin (same as M-1 Garand). There are a few possible causes which will create slam fires. If you are handloading, for any semi auto and want to be safe, use a small base full lenth sizing die. Go one step further and strip your bolt so that it slides into lock up with finger pressure. Take a resized case and see how it chambers. If you have to force the bolt forward to fully seat the bolt lugs, then you need to keep adjusting your sizer die until you reach the point where your bolt lugs engage freely.Lock the rings on your die,reassemble your bolt. This will at least eliminate one possibility of your slam fire. Another thing to look at is primer seating depth.Ensure that your primers are not high. I use the CCI #34 "NATO" primers which are a little harder material.The next thing you should consider with any semi is clean, clean, clean. If your gunsmith has headspace gauges,get him to check it out. These are mass produced rifles and I have heard through the grapevine of the odd bolt lugs being slightly out of square which will create headspace problems.As far as improving accuracy, the sky's the limit if you want to spend the cash. I would start with a walnut stock and a good glass bedding job by someone with experience.

Yes you are right, it is the receiver bridge. The M14 design, as complex as it is.......it's very safe. The bridge prevents out of battery firing.......but you are at a very fine line here.......as the bolt turns to lock up into the lugs the hammer could be pushing on the firing pin. Although the design is very safe......it's not 100%

Thanks for the info guys, after the the second time it slam fired I began shooting the rifle single shot so I could get some load info built for it. I already have a gunsmith looking at it and he will fix the problem shortly. I have tried the after assembley test and there is no problems!!! I asked if maybe I was riding the recoil and was touching off the second shot by accident???? The rifle did not go full auto it only cycled the second round and then closed as it should on the third round???

I have cleaned the bolt, and the rifle very well and the rifle seems to shoot reasonably well. I did set the Lake City match ammo back .010" so to crack the seal!!! I also found when I had my snow camo on the gun it seemed to shoot a bit better maybe it needs a little tweeking!!

Hey Turf :

Eveyone has to start somewhere and I thought a question maybe dumb as it is was better than a stupid mistake, Maybe tell the "whole chicken" to lay off and get some rest so you are not so grumpy!!!

I've had 2 Norinco M-14's that slam-fired. It was an easy fix to stone the trigger hooks to engage properly. This is a common problem with Norinco triggers. More than likely you have a light trigger pull. If that trigger is breaking lighter than 4.5lbs you will have slam-fire problems. Take it to a smith who can fix it, if you don't understand trigger designs to affect repairs yourself.

Accuracy can be 1 MOA to 1.5MOA with a stock Norinco with match handloads. I've never seen better and have seen 4MOA despite my efforts. If you're getting 1.5MOA you have a shooter. Good Luck.
