Brown Tip Frangible .223Rem

[giggitygiggity]

I picked up some 50 grain brown tip frangible bullets show here: https://americanreloading.com/en/22-caliber-222-227/630-223-50gr-brown-tip-frangible-1000ct.html. Does anyone have any experience reloading these? From my research, I should use loadings for 62+ grain bullets since the brown tip frangible bullets are longer than their FMJ counterparts. Does anyone have links to recipes or any tips/tricks/favorite loads for these bullets.

All of you Safety Sallies can cool your jets as I always cross-check any recommendations. However, I am asking due to a lack of published data concerning these bullets. Thanks.

What is the twist of your barrel ? If it's 7,8,9 or maybe even 10 those bullets should stabilize just fine . Do you know the velocity range they are designed to work at ?

In my experience, frangible rounds need a bit more fps in order to sinter on impact. When I tore down one of the 5.56 rounds we use/used in our plywood shoot house it was at the 2.260 COAL and had 25.0 grains of what resembled AA2230. The actual seating depth put the base of the projectile in the powder (almost a compressed load) similar to the .223/5.56 tracer rounds.

For reference, here is the image for the 5,56 tracer dimensions from the Army munitions manual:

I have multiple ARs with different twist rates. The one from which I intend to shoot these will be a 1/8. I am not sure at what velocity they’re designed to work... basically, I saw them on American Reloading’s site and got them for a decent price after discounts so I figured I could see if I could work up a decent load. I might use them for coyotes or groundhogs around my house, but I’m not sure if they’d work well in that application. If not, I’ll just plink with them.

Great replies. The COL measurements are useful. I assume they’re 50gr loadings?

 

[Akula69]

I cannot say what the military rounds are loaded at (for), but I load my 5.56 with recipes for 62 grain weight. I've been loading both the tracer and the SS109 with 25.1 grains of AA2460 over a CCI primer.
