SUBSONIC 223 LOAD DATA H335 MANUAL

I posted 25 grains of H335 for a 55 grain bullet for my LONGER throated rifles and the #9 Hornady manual for a 'SHORT' throated. Meaning any load data given here like what I posted earlier 'may' be too hot for your rifle. 223 with the shorter type throat so be careful. 223 and the throat on the Savage is the same length as my AR15 rifles. I have two AR15 rifles and a Savage bolt action. You say 'I am trying to load for a 223 Remington with 55r bullets' BUT didn't say what type rifle. And I hope you know your asking a 'loaded' question. I was just looking at this post to see what had been added and went to your original load question and the light bulb came on. Hornady’s 75 grain 223 TAP load produced three 10-shot groups fired in a row at a distance of 100 yards from a Krieger barreled AR-15 that had an average extreme spread of 1.03” with a 30-shot composite group that had a mean radius of 0.32”.Pretty much what the title states, I am trying to load for a 223 Remington with 55r bullets and was hoping someone had a good recipe with H335. Hornady’s 75 grain TAP FPD produced three 10-shot groups fired in a row at a distance of 100 yards from a 20” Colt HBAR that had an average extreme spread of 1.14” with a 30-shot composite group that had a mean radius of 0.37”. I haven’t spent any appreciable time hand-loading the T1C projectile, but I have done a fair amount of shooting with the factory loaded versions of this bullet. The 75 grain BTHP pointed, has an average G1 ballistic coefficient of 0.353, while the 75 grain TapFPD, has an average G1 ballistic coefficient of 0.344. Both of these references show identical dimensions for the projectile, yet have different ballistic coefficients listed. On page 63 of the book, the T1C is referred to as “75 grain TapFPD”. On page 58 of the book, the T1C is referred to as “75 grain BTHP pointed”. The third edition of Ballistic Performance of Rifle Bullets has some conflicting information on the T1C (the version with the cannelure.) This process is conducted in a semi-progressive manner on a Dillon XL-650 press using a Pact Digital electronic powder dispenser and scale to dispense a powder charge of 24.1 grains of the VihtaVuori N140.Īccording to Ballistic Performance of Rifle Bullets by Bryan Litz (2nd addition), the Hornady T1 has an average G1 ballistic coefficient of 0.356. The cases are primed with Federal GM205M primers and charged with VihtaVuori N140 powder and as mentioned above, the T1 projectile is seated to a COAL of 2.245”. Don't even view this information in the presence of children or small animals.įor this hand-load of the Hornady 75 grain BTHP bullet, I use virgin Lake City brass that has been weight-sorted, match-prepped and neck-sized. Usage of this information for the actual loading of ammunition may result in malfunctions, damage and destruction of property and grave injury or death to beings human in nature or otherwise. No warranty, guarantee or assurance that these loads are safe is stated, suggested or implied nor should any be inferred. It is not intended to be used for the actual loading of ammunition by the reader. The information provided here is for educational purposes only. Reloading is an inherently dangerous activity. These figures are contingent upon a variety of variables, such as the particular chamber reamer that was used for your barrel, the number of rounds that have been fired through your barrel when the measurement is obtained, the particular lot of bullets used and whether you use a virgin case, a fired case, a resized case or a head-space gauge to obtain this measurement. The jump to the lands figures stated above where obtained using a Sinclair bullet seating depth gauge and a Forster 223 Remington 1.4636” head-space gauge. When fired from a Larue Stealth barrel with a 223 Wylde chamber, this COAL will create a jump to the lands of 115 thousandths of an inch and when fired from a Krieger barrel with a 223 Remington chamber, this COAL will create a jump to the lands of 78 thousandths of an inch.

When fired from a Colt SOCOM barrel with a 5.56mm NATO chamber, this COAL will create a jump to the lands of 178 thousandths of an inch. The lot of T1 projectiles used for this article have a nominal length of 0.988” and I load them to a nominal COAL of 2.245”. According to Ballistic Performance of Rifle Bullets by Bryan Litz, the Hornady 75 grain BTHP has an average G1 ballistic coefficient of 0.356 and an average G7 ballistic coefficient of 0.183. I use the Hornady 75 grain BTHP bullet to load match-grade hand-loads for my semi-automatic AR-15s chambered in 5.56mm/223 Remington.
