Tapered Throats, the Grendel, & History

[JASmith]

There is a paper on Ammoguide.com that describes tapered throats, the Grendel, and suggestions for bullet makers for optimizing bullets. The discussion gives some insight for handloaders too: Why are Tapered Throats Reappearing?

If that link doesn't work, try the same paper at Brenneke Throats and Repeating History

The paper grew out of the many discussions on this forum five or so years ago about the Grendel compound throat.

Good read sir. Thank you for posting it.

Very interesting. Thanks for posting.

If "stay away from" means the bullet generally turns in poor accuracy AND that we are committed to send queries to the manufacturer about the accuracy issue, THEN compiling a list of poor performing bullets might make sense.

The query will give the bullet makers a chance to give advice we as a community have so far overlooked and give them chance to make changes to their design and manufacturing processes.

Absent contrary guidance from the moderators, mentioning those bullets in this thread is, in my view, an appropriate part of the discussion about bullet design guidance and handloading tips.

Go for it! A bunch of lousy bullets out there just like lousy barrels and bolts.
