I am wondering if anybody out there knows where you can purchase the harder mil spec type of primers such as cci#34 or similar. Concerned about slam fires with my new poly 305 m14, They dont seem to be availible in Canada
 
I would not be concerned! Myself and my buddy run civvy Federal ammo and reloads using Winchester and Federal LRP through the M14's. Never ever had a slam fire!
 
I got a few 1000 CCI #34s, which are the only MILSPEC LR primers commercially available, from Wholesale Sports some yrs ago.
I also use Win and Rem primers in the M14/M1 with no problems subject to the caveats that primers are always seated below flush with the casehead and brass is FL re-sized.
 
Regular primers are just fine; just make sure your primers are properly seated to avoid slamfires.
 
I've never taken the time or the $ to find # 34 CCI primers. :eek: My #### is still here (I think) and I only (I'm a cheap basturd) use whatever I can find in large amounts like the WLR and Fed 210 primers LR.

Slamfires? Just load from the M14 magazine (even if it's one at a time). Just leave the magazine locked into place and place the fresh cartridge inside the right hand edge of the follower (go and look at one of your mags.... :rolleyes: ) and merely tap the op rod to the rear. Listen for the music as the bolt lock trips and the bolt rides forward! It's music to us NRA High Power shooters (Stage 1 200 yard off hand, standing position)

Hope this helps you save your money! :D

Cheers,
Barney
 
Don't use Fed 210M match primers.

I spent a very exciting afternoon at the range with those once. You just never knew when the rifle would rip off 2 or 3 rounds in succession and in something as light as an M14 that can be somewhat disconcerting.

Regular CCI primers seemed to be fine though as they have a slightly harder cup.
 
CCI "milspec" primers are nothing more than a marketing gimmick for magnum primers. Magnum primers burn a bit hotter for a bit longer and are about the powder used. They're made to ignite hard to light powders and extreme cold weather shooting. You don't need 'em.
Slam fires, never seen one in 30 plus years, are caused by improperly seated primers, not the rifle.

Thanks for responding. Being new to semi auto game I noted on other forums that there is lots of hype on this subject. But I guess that it is of no great concern. I noticed when I cycled a few rounds through it to check the function that the primers had slight dimples on them. Read in the manual that this normal, so that they reccomend surplus ammo or mil spec primers. Anybody else notice dimpled primers.

"...lots of hype on this subject..." Lot of nonsense too. Starting with "milspec" primers being required. Millions of rounds were loaded and fired out of semi-auto battlerifles long before CCI's marketing types came up with the idea of calling a magnum primer "milspec".
Loading for a semi requires FL resizing, every time, and watching the case lengths and OAL. Other than that, it's no different than loading for any other rifle. You don't need FMJ's either.
 
Ditto To That

I have loaded about 200 rounds for my M14 here. Lots of good advice. I use Win all powder and have started using the CCI mag primers (I used them with my .223 loads and have fantastic results). My rifle shoots pretty consistent after Hungry's clinic and have not noticed as many flyers with my new load.

Be careful with all the hype as well. I was a basket case after reading the 1000's of posts online. I have found that generally, the folks on the GunNutz forums are genuine and have some good advice. Still, it is the internet. Hungry and M14 Doctor really know their stuff and give honest advice. :D
 
I have used 210 match primers with out any problems I do however clean my primer pockets every time and make sue that they are seated to correct depth

I think this sums it up pretty well.............;)

I have used pretty much all available primers and never had a problem................just watch your seating depth..............
 
Hey Skullclown....elaborate on the seating depth for me. I'm just about to do some experimenting with seating to the max lenth that can fit in the mag. And yes I measured the chamber :D

For primer seating, make sure the primers to not protrude above the case head ( what we call a "High Primer")..........you want them seated flush..........:D

actually slightly below flush 5-10 thou ,you should feel the difference with your finger as you move it across the base of the cartridge and for sizing I use a small base die it rules out any problems of variances in the tolerances of the sizing fies as well I find that the rounds I reload shoot very accurately out of the M1A

No - Safety is not just a marketing gimmick. They are being used for a good reason - additional safety margin. RE Video

Wrong again - Slam-fires are not only caused by improperly seated primers. Firearms components such as out of spec firing pins etc can cause a slamfire in a self-loading firearm also.

Simple explanation why harder than normal primers are used for self-loading firearms.RE: From the CCI Web site.
Military-style semi-auto rifles seldom have firing pin retraction springs. If care is not used in assembling ammunition, a “slam-fire” can occur before the bolt locks. The military arsenals accomplish this using different techniques and components—including different primer sensitivity specifications—from their commercial counterparts. CCI makes rifle primers for commercial sale that matches military sensitivity specs that reduce the chance of a slam-fire when other factors go out of control*. If you’re reloading for a military semi-auto, look to CCI Military primers.
*Effective slam-fire prevention requires more than special primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, cartridge case condition, and other factors can affect slam-fire potential.

Alternative choice may be Winchester (WLR & WSR) primers have a fairly hard primer cup and are currently being used in some mispec ammo such as the Winchester 5.56mm white box and AE ammo and thus a few decades with proven success.
