CMP .30/06 Warning

[Singer B]

Good morning! I just received an email from CMP reference a warning to not use .30/06 ammo that has a CUP rating higher than 50,000 and/or uses bullets with a weight of 172 grains or more. Per the warning email, it states this applies to M1 Garands, 1903s and 1903A3s. The CMP warning states that these rifles are all over 70 years of age and "not designed for max loads and super heavy bullets." I hope this is helpful to those who are not on the CMP mailing list.

The CMP and GCA are both outstanding organizations staffed with competent and helpful people and worthy of support.
If anyone did not already know.

The warning certainly isn't new, although maybe rephrased. Similar warnings from them regarding factory 30-06 in the past. I wonder if there was an "incident".
I don't quite understand the bullet weight warning though, unless the context is factory ammo or an attempt at a "catchall" statement. Sounds like a general CYA warning in response to an incident. I'll have to check for sure, but I think the M1 booklet they ship with the rifles has a similar warning regarding factory ammo and hot loads.

so I actually got 2 emails. the second had "revision" appended to the subject line. Here they are for posterity.

when read properly it says this..

They said ammo that is OVER 50k CUP AND 172 gr is bad.
However...


50k CUP is SAAMI max so ALL commercial ammo is under this.
In essence CMP just stated all commercial ammo is fine. Only the 172gr limit applied if it was OVER SAAMI spec.

Thanks Jeremy. You are correct - I just caught there was no Oxford comma before the word "and".
