are fed 210 m primers

[Cali_Ed]

Are these to soft for a ar308308?

watched a video by ammosmith

stating a semi auto may set of the primer as the bolt is engaging before you hit the triggger. Seems pretty harmful.

Reason I ask is because on 6mmbr.com

It is listed as the most used in accurate loads. There's a chart I'll look for it. Thoughts?

Down here brother two shops 40-50 a brick lol

[MONTANA308]

Got some here in MT. Its all I load in my large rifle cartridges. Never had any go off when not supposed to.

[survivalshop]

  I still have a few & use them for load development , have had no problems with them , but some say they are too soft for AR's . 

[Cali_Ed]

Well I managed to get a pack of 100 f210m primers I'm going to test them out with some hornady brass with varget and rl15 should be fun

[MONTANA308]

I had been running 44gr of Varget in hornady match brass with the 210m under a 168 SMK. Set at mag length. Shot ok. I need to start a latter test over again and dial the Gaser back in. Though could be the nut behind the trigger to.

[Cali_Ed]

I'll go ok it up, but il ask any ways how do I do. A ladder test? 3 round each and keep increasing charge and see what does better?

Personally I would not use Fed 210M in the AR or M1A/M-1. The reason is the possibility of the round being fired before the bolt has the chance to rotate and lock.

If the round is striped from the mag, there is a lot less chance of this happening. If one throws a round in and lets the bolt fly fwd, the chance of a slam fire goes up over other primers. The firing pin keeps moving fwd before the bolt rotates and has enough energy to strike the primmer and set it off.

 

I assume the Armilite still have the spring that keeps the firing pin to the rear to prevent this. DPMS guns do not, hence the floating firing pin.

 

Over 30 years of HP shooting, I have seen on the range or have been right next to rifles blowing up. About 11 M1A's one M-14, and two AR 15.

 

Because of this, learning by others mistakes, I stay away from fed primmers. I do use them in my bolt guns.

[Cali_Ed]

Then what primers do the store bought fed match bthp come with?

[MONTANA308]

I usually start about middle of the load range and go up by .3 gr till I hit max and after shooting max and there is no pressure signs ill go up a bit. Once I find what powder load the rifle likes ill work on seating depth I usually start everything at 15 thousandth off the lands. And if it dont shoot ill adjust.

[MONTANA308]

In your gas gun your gonna be held to mag length about 2.800 is max in my mags I usually start there and seat deeper if its not shooting how I think it should.

What bullet and powder you looking to use

[Cali_Ed]

I'm actually going by increments of .3 brother lol, using varget and 175smk . Gas gun

[Rsquared]

I assume the Armilite still have the spring that keeps the firing pin to the rear to prevent this.

Just for the record. Yes, Armalite still utilizes the firing pin spring.

[Cali_Ed]

Well gonna try my make shift ladder test tomorrow

[392heminut]

Those sure are purty bullets! <thumbsup>

[survivalshop]

   Was it you that said no colored bullets at the range ? <laughs>

[Cali_Ed]

Lol, the ones with the plastic tips

[Cali_Ed]

Here's the chart with the tips that aren't allowed.

[survivalshop]

  Ya, that has to do with Military ( Surplus ) Amor Piercing , Incendiary & Tracer Ammo , your flex point or Ballistic Tip ammo is permitted ( well , maybe not your magic marker tipped fodder <laughs>  )

  They would be banning 50-60 % of the Hunting ammo out there , if they were included.

Lmao
