Anyone ever used a barrel doughnut?

[.300 Dakota]

I've used one on 2 different rifles back when they first came out, and as near as I could tell, it did NOTHING. I moved it all over the barrels and even tried it backward! FYI: If you ever see a rifle for sale wearing one, AVOID IT LIKE THE 'RONA!

What will work is a tuner brake if your barrel is threaded. It's $250 or more vs $30, however... This is the old Browning BOSS without the patent.

I've had good results with them with many rifles, mostly ARs and one bolt with a lighter barrel. Most of my rounds are loaded to max mag length and after the charge weight is determined I use the doughnut. I might be able to get better accuracy adjusting seating depth but I think it is superfluous for me. I had two rifles it didn't work on. The first would switch between horizontal, diagonal and vertical stringing as I moved the doughnut. For the second, I was able to match but never improve upon the best load. Both those were bolts with heavy barrels.

doubt the debate will ever be settled. Much like the .270 vs .30-06 ('06 is better).

Now you done it, this will turn into 26 pages and no more doughnuts.
