Terminal Ascent accuracy issues?

[rockymtnsam]

I picked up a box of Federal Terminal Ascent for my 6.5 PRC last week. I’m shooting a Seekins Havak PH2, and every bullet I’ve put through it so far (140 AB, 142 ABLR, and 147 ELD-M) has shot sub MOA, the rifle is much more capable than I am.

Yesterday I went out to shoot the 130 grain Terminal Ascent and could not get them to group at 100 yds to save my life.

A couple of quick points:

1. I did not clean my rifle after the last time I shot it, and am wondering if the cooper/lead combo is somehow causing accuracy issues since my barrel wasn’t clean.
2. I put the 140g Nosler Accubonds back in, and shot 3 holes touching at 100 immediately after shooting the TAs. Then I dialed to 350 and hit steel dead center. Doesn’t seem like a rifle issue.

Has anyone else had similar issues?

I have not had that issue with the TA's. Although mine is 7 PRC, they are the most accurate and consistent out of my rifle between them and both ELD's. Which copper bullet did you shoot? In my 300 PRC, if I tried shooting non-coppers after shooting LRX's the accuracy was terrible until I deep cleaned the barrel and then it goes back to normal accuracy.

Why are you puzzled? Some guns/barrels just like certain bullets/powder/ammo combinations and dislike others. Quite normal.

Makes sense. I was just thinking because the TA is a copper shank and lead core that it may have something to do with the accuracy.

Just kind of shocked I guess because the rifle has shot a few different rounds so accurately and I’ve read almost all positive reviews of the Terminal Ascent. But I agree! Especially since it likes the Noslers so much

What one gun likes, or what reviews may say, means nothing in your gun.

Yep, somewhere someone else has a 6.5prc that will put Terminal Ascent through one hole but won't keep 140 Accubonds on a dinner plate. Each barrel is an individual.
