90 grain 223 bullets?

[dxt20]

i have seen on some reloading data sites that there are 90 grain .224 diameter bullets. i know that is an extremely heavy bullet for any 22 caliber rifle. but has anyone heard of these and who manufactures them? thank you

Here's an article on the Jimmy L. Knox 90 grain 22 caliber bullets. www.6mmbr.com/T2K22BR.html

does anyone know where you can purchase these bullets?

You probably need a 1-6 twist barrel to shoot those and might get by with a 1-7. Mike

Yeah, in the article I found they were using a 1-6.5 twist. Those are some long slim bullets. I thought the 69 gr. Sierras I used were long.

You can get 90gr Sierra MatchKings or Bergers fairly easy. They will not fit in a magazine though and guys are shooting 1000yds with them at Perry.

I tried using them in a bolt gun with a 7" twist. They, bergers, shot .5 MOA but were much slower compared to 80 grainers which shot .25 MOA. I stayed with the 80s.

I found that out of my AR the 75gr bullets actually shot best at longer ranges (500 ~ 600 yards). My barrels like a max charge of N540 and that propel the bullets at 2950 ~ 3000 fps. If I go with a heavier bullet, I start loosing more velocity than I gain with the higher B.C. 75gr burgers give me the most consistent results, but the 75gr A-Max did pretty good to.
