I've used up to 25 grains of H335 for this bullet and it's worked well. If you're just plinking start around 22-23 gr and work up until you have a load that doesn't short stroke the bolt. Save wear and tear on the internal parts of the rifle.

According to TM 23 0001 27 (The military Small Arms Ammo "Bible"), when this bullet is loaded as part of an M855 round it's propelled by 26.1 Gr of WC844. WC844 is "supposed" to be the same as H335.

Speed is 3025 fps and pressure is 55,000 psi. Just remember that this is also in a Milspec case and has a crimped primer. If you try to dupe this military load, work up with caution. Also, the military measures speed 76 feet from the muzzle so it will be a little slower than that measured at more traditional distance of 10 feet.
