7PRC Nosler Accubonds

[CHamilton13]

A few months back I bought some Nosler 7PRC ammo in 160 Accubonds to try out in a new build.





Fast forward a few months, I received the rifle and spent the last few nights shooting and getting it dialed in. Tried 180 ELDms, 160 LRX, and the 160 Accubonds. The Accubonds were the clear winner shooting close to .4 across 5 groups. I set my zero stop, and ordered 3 boxes from Midway.





Today I received them, completely different seating depth from what I had been testing all week. Literally a quarter inch difference. Has anyone else heard of this?





I have a call into Nosler but no response yet. I haven’t shot them, but I’m sure by the fact they are a quarter inch shorter than SAMMI spec, that will certainly affect things and possibly velocity.

Lot to lot variation exists but this seems extreme. You’re certain they’re the same grain bullet?

Top box was the original ammo that was sighted in, the bottom three are the ones that arrived today. They are 1/4” short and also have a cannelure when the original box did not…

Gotta wonder about Nosler quality control with Nosler being expensive ammo.

Would venture that the cannelure is the culprit, they probably seated to the cannelure on the newer boxes.

i don't think that bullet is suppose to have a canneluer

what did Nosler have to say???/

I think that many of the nosler bullets made for ammo have a cannalure where the same bullet sold as a component would not. Its why so many of the over runs from Nsoler/SPS have cannalures. In my experience shooting seconds/overruns from Nosler/SPS they shoot pretty much the same and kill game just fine. cannalure or not Not that addresses the OAL issue and what ever else Nosler might have changed with the OPs ammo.
