Home Forums Reloading Varmint Rifles Please share your 223 Rem 55gr bullet loads with H335

I use 25 grains of H335 in my AR15 rifles.

I did a Google search on this same subject and 24.7 and 25.0 were the majority of the replies. (for the AR15)

I then fed this into Quickload using Lake City cases with the most case capacity with 30.6 grains of H2O. And cases with the least capacity of 28.0 grains of H2O.

The purpose of this was to shoot mixed .223/5.56 brass for close range practice at 100 yards or less and "NOT" exceed the max pressure of 55,000 psi.

Below Lake City brass with the most case capacity of 30.6



Below cases with the least case capacity at 28.0 grains of H2O



As you can see there can be a 6,000 psi difference in chamber pressure between a "few" cases. And as you can see below the majority of the American made cases only vary a few tenths of a grain in capacity.



My 2 1/2 cents

NOTE: The load above are NOT for short throated .223 rifles and were worked up for the AR15 rifle with its loner throat.
