I am working up a load using 55 grain moly-coated hornady Vmax bullets, 19 grains of IMR 4198, federal primers and mixed brass. This will be mostly blasting ammo and for the occasional critter in the back yard. Shooting out of a 14.5in Bushy Ar. Any opinions?

Why the moly coat?

For a blasting load I'd go for some plain 55 gr FMJs or something. I'm sure they'll expand/blow up just fine and whatnot, but for what you're describing, I'd just nab some cheap bullets and get to it.

I didn't look up the charge weight range for IMR 4198, but that is one gunpowder I don't like much due to the long grains and poor metering. There's a pound downstairs and when it's gone I won't get more.

Skip the moly...because it is ill advised to switch between naked and coated bullets in the same bbl without a good scrub down of the bbl.. Moly bullets need to have the barrel sweetened....so if COLD BORE shots are a concern.....stick with naked bullets.....

In my Speer #10 I have handy 20.0 grs of IMR-4198 is the starting load with a 55 gr bullet.

19.0 grs is start in Lyman #49.

So no problems with that powder charge.

Myself I like to load 223 with slower powders, BLC2, Tac, IMR-3031, IMR-4895, Re15 ect.

Moly coated bullet is ok if that's all you have, or you want to shoot Moly only.

running 55 gr Hornady Vmax on top of 19.7 gr H4198, seems to be accurate in my rifle

I use 19.8g of IMR4198 with Hornady 55g FMJ, and it is very accurate out to a 100m out of my 16 inch barrel.
