Hammer bullets stabilization

I would have a talk with the person who made it. That's a pile of bullets you can't shoot when you should have.

It happens more than you would think.

I ordered a Carbon barrel in 10 twist and it showed up as a 10.25. Only questioned it when the 181 impacted sideways. Now all barrels get ordered with a faster twist than needed and get checked with the old tight brush as soon as I get them.

Yep, a while back I ordered a 7" twist barrel from a big name and got an 8. It works fine but always trust but verify.

I know some folks are trying to run hammers in minimum twist barrels and some are having issues with key holes.

Is there a post about key hole issues? I couldn't find one.
I just tested a 1:11 TR bullet suggested by hammer in a 1:8 TR barrel out to 400+ yards with no issues.

For me I didn't find this out until shooting heavy mono's with Steve, so I don't have a pile of unused bullets,

The barrel was over 35 years old at that point, and tough to walk back, as it's been great in every other way.

I don't know if there is a post, but yes I've seen this. Not just with mono's.

There has also been a fair amount of experience with the lighter bullets (better stabilized) out penetrating heavier versions.

A bullet may group "OK" but fail to perform terminally, as it doesn't land squarely on the HP, or track well after impact.

It also likely won't yield it's best BC

I don't think there was a specific thread but I recall seeing posts about key holes.
