M852 Primer Question

[Alaska]

What Primer was used in the M852 load was it a magnum primer or a standard large rifle primer with IMR 4895 ?

As I recall, it was a standard LRP that wasn‘t crimped. it’s been a while since I’ve shot any.

Believe it was a standard primer.

Yes the load varied on lot by year manufacture due to variations of IMR 4895 but 42.0 to 42.2 is good place to start.

Yep. Powder charge will change depending on powder lot. Load for velocity. You can used magnum or #34 just use a chronograph and load for the velocity of the load.

I used either #34 or #200 with my M1A along with IMR 4064 with the 168gr SMK. RE-15 does very well under a 168 as well.

I'm not as up to snuff on primers as others on here... But I do know that CCI uses magnum priming compound in the #34 primers. So in effect, they can be considered a magnum primer.

Mike yes both the #34 and #41 are magnum primers . I think they had another military primer just for the M852 I trying to do research . After some intense digging found the answer. It was the CCI # 43 large Rifle primer never released to the public in M852.
