.223 mousefart load help

[uscra112]

Now there's a REAL mousefart load!

What about trailboss?

Not really a "light" load, but I shoot NOE 60gr powder coated RN over 8 gr of Unique. Accurate, and cheap.

1.5g of titegroup with the Lee 55g rf boolit w/o a gas check out of a 16" AR was running 700ish fps. Buddy ran some through his suppressor and it was Hollywood quiet.

I got very good results with Bullseye in my 223 T/C carbine. I used about 3 gr and put in a magnum primer for more consistent ignition.

Vitavourhi N310 and N320 are both good powders and burn cleaner than bullseye. The 310 is a bit faster but super-small powder particles are a pain to work with.

For the most bullet energy output with minimum noise you want:

The heaviest bullet- takes more energy from the hot gasses
A soft lead bullet- upsets into bore better, pushing up initial pressures and is more accurate
Minimum case capacity- bit tough without a new gun
A flat base bullet. Better stability with long slow bullets
A round nose bullet. Shorter so more stable.
Minimum powder- less gas. Lower pressure when bullet exits
A fast powder- increased pressure with lower powder charges.
Good bullet lubrication- safer and allows slightly lower powder charges.

The idea is you use the minimum amount of powder and get as much energy out of it before the bullet exits the barrel. This makes the least bang.

Keep the velocity below 950 fps or supersonic noise from the bullet will ruin it all.

Most .22 airgun pellets are actually 5.5 mm (.218). You might find they are a lot less accurate than proper .224 cast bullets.

I've used a small rifle primer and a 22 caliber pellet with no powder it worked great in a M16 used to train troops in a hallway,even cleared out a few rats along the way.

titegroup... 3.1 grains... 55gran fmj.. etc.... 1064 fps 4000cup .. right from hodgdons site.

Cast are better than jacketed. Less likely to get stuck and a lot easier to get out if they do get stuck.
