Did FGMM change?

[f15david]

I have used FGMM 308 168SMK for the last few years with consistent results. I just purchased a case (same part number GM308M) and it came in different packaging and shoots 1 MOA lower than the previous FGMM (Compared side by side). Curious if Federal changed anything with their recipe? It still groups the same just with a different point of impact. Thanks for reading

1 moa lower at 100 yards?

Did you chrono the new rounds to see if there was a velocity difference?

Sorry, yes 1 MOA at 100 Yards

I don't have a chronograph unfortunately

Maybe they are shooting slower

Show us the new packaging...

Also, what round count on that barrel? Possibly it's losing speed already!

They changed packaging a year or two ago.

Assumed same performance.

I've shot old box and new box, didn't change anything in my scope. Might be a tenth plus or a tenth minus but that's probably environmental or my physical being.

New box on the bottom. Unsure of the round count on my rifle but I shot the boxes side by side and the POI would change back and forth.

The new packaging is on the top, not the bottom.

Well if that's the case, I just got sold an old stock of ammo from target sports USA

When the Hell did the box change?

Thanks for the replies guys. I appreciate you helping out

Look over the red box really well. My red box (lower) ammo just like yours, has a date of 2009 on it. The lower boxes have been around over 10 years. Your top box ammo is a newer packaging and it looks like Federal has even newer packaging than that.

They did change the powder for sure, I just don't know when. Use to be 4064 now it's arcomp.

Quick update. Federal got back to me regarding the date code on the case packaging and it was manufactured in early 2019. Both have brass casings have the same headstamp and blue sealant on the primers. I guess it is what it is.

Was not aware of that. Where can one find that info? Is that for 168s and 175s?
